The best rain gauge replacement tube for most yards is the JMBay 7 inch Plastic Rain Gauge Replacement, with large-font inch markings and a 2.16 in diameter. Its 7 in capacity, 8.26 in height, and 2 included tubes give you more points to compare with your current tube.

A close-looking tube may still sit loosely or fail to fit the holder. Measure your tube, including its lip or bevel, and compare those measurements with a replacement before buying.

A rain gauge collects precipitation for you to read against a scale. If you need a refresher on the instrument, start with [What Is a Rain Gauge?

How we chose the best rain gauge replacement tube

We compared the materials, capacities, dimensions, scale details, and package contents of each option. A tube's measurements and rim shape matter more than its capacity label, so picks with dimensions you can compare are easier to screen for fit.

The scores reflect how each set of stated features matches common replacement needs, such as finding a readable scale, choosing glass or plastic, or replacing a tube from a particular brand. A match to your existing gauge can outweigh a higher score if the dimensions or rim differ.

Which replacement tube dimensions should you compare first?

Start with the height, outside diameter, opening, and rim shape of your current tube. Those measurements help you rule out options that are too short, too wide, or shaped differently at the top.

Remove the tube from its holder before measuring. Record the height from bottom to rim, the widest outside diameter, the opening across its inside edge, and the shape of any lip or bevel.

Capacity matters too, but it describes the scale's measurement range rather than whether the tube will fit. A tube marked 7 in could still have the wrong opening for your holder.

If the original tube is broken, measure the holder and look for the gauge's brand or model. If you're replacing the whole gauge, compare AcuRite rain gauges for the yard.

The rain gauge replacement tube sizing guide explains what to measure and how to compare sizes.

The best rain gauge replacement tubes

These choices include glass and plastic tubes in 5, 6, and 7 in capacities. Each option suits a different combination of scale preference, dimensions, package contents, and brand fit.

JMBay 7 inch Plastic Rain Gauge Replacement: Best for garden readers

9.7/10Our score

• 7 in capacity
• 2.16 in diameter
• 8.26 in height
• Large-font inch increments
• 2 tubes and 1 brush

The plastic tube pairs a 7 in capacity with large-font inch markings. Its 2.16 in diameter and 8.26 in height give you a starting point for checking fit.

See it on Amazon

Pros

• Large-font inch increments
• 2 tubes and a cleaning brush
• Plastic construction

Cons

• Confirm the rim and opening fit your gauge
• Plastic may not suit buyers who prefer glass

JMBay's plastic tube is a strong general choice if your gauge matches its stated dimensions. The scale uses large-font standard inch increments, and the package includes 2 tubes and a cleaning brush.

JMBay describes the plastic as thick and less likely to freeze-crack or break easily. That makes it worth considering if you prefer plastic, but the dimensions and rim still need to match your gauge.

Choose this when you want a readable plastic two-pack and a brush. Skip it if you specifically want glass or your existing tube has a different opening or rim.

2

JMBay rain Gauge Replacement Tube Glass: Best for glass preference

9.5/10Our score

• 7 in capacity
• 2.16 in diameter
• 8.26 in height
• Glass construction
• 2 tubes and 1 brush

This glass replacement has a lip, 7 in capacity, and large-font inch markings. It comes as a pair with a tube brush.

See it on Amazon

Pros

• Glass construction
• Lip design
• 2 tubes and a cleaning brush

Cons

• Confirm lip shape and rim fit
• Glass needs careful handling

This JMBay option suits buyers who prefer glass and need a lip at the top. Its 7 in capacity and stated dimensions give you clear measurements to compare with the original tube.

The package includes 2 tubes and a cleaning brush. Check that the lip rests properly in your holder before buying, since a matching body diameter does not confirm that the rim will sit correctly.

Choose it for a glass two-pack with a lip. Skip it if your gauge uses a plastic tube or a different rim shape.

3

BIUWING 7" Capacity Glass rain Gauge Replacement: Best for one replacement

9.2/10Our score

• 7 in capacity
• 2.16 in diameter
• 8.26 in height
• Glass construction
• Clear scale

This single glass tube has a lip and a clear scale with standard inch increments. Its stated dimensions suit gauges that match that size.

See it on Amazon

Pros

• Glass construction
• Clear scale with inch increments
• 7 in capacity

Cons

• Only 1 tube
• Check the lip and opening against your gauge

BIUWING's glass tube is the single-tube choice in this group. It has a lip, a clear scale in standard inch increments, and the same stated body dimensions as several 7 in options above.

Choose this when you need one replacement and prefer glass. Skip it if you want a spare tube in the same pack, or if your existing tube's opening and lip do not match.

4

HOBYLUBY 5'' Capacity Rain Gauge Replacement Tube: Best for shorter gauges

9.0/10Our score

• 5 in capacity
• 1.37 in diameter
• 5.9 in height
• 1.88 in opening
• 2 glass tubes

These glass tubes have a 5 in capacity and a stated 1.88 in opening. Compare the opening and tube dimensions with your gauge.

See it on Amazon

Pros

• 5 in capacity
• Opening dimension provided
• 2 glass tubes

Cons

• Smaller capacity than 7 in options
• Confirm the opening and rim fit

HOBYLUBY is the 5 in glass option, with a smaller body and a stated 1.88 in opening. The package contains 2 tubes, so it may suit a shorter gauge that needs a pair of replacements.

Compare the opening as well as the height and diameter before ordering. A 5 in capacity alone does not make this a fit for every 5 in gauge.

Choose it when your original tube is close to these dimensions and you want glass. Skip it if your gauge needs a 7 in range or a wider tube.

5

Lueudu 2PCS 7" Plastic Rain Gauge Replacement: Best for tenths markings

8.7/10Our score

• 7 in capacity
• 8.23 in length
• 1.6 in inside opening
• Plastic construction
• 2 tubes

The plastic tubes have a blue strip and a scale marked in tenths. Check the 1.6 in inside opening against your gauge.

See it on Amazon

Pros

• Scale marked in tenths
• Blue strip may help with readability
• 2 tubes

Cons

• Opening differs from many 2.16 in options
• Check the scale and fit before choosing

Lueudu's plastic two-pack has a scale marked in tenths of an inch and a blue strip at the back. The scale has 10 graduations per inch, and Lueudu says the strip helps reduce reflection and makes the scale easier to read from a distance.

The stated inside opening is 1.6 in, which differs from the 2.16 in diameter given for several other 7 in tubes. Compare the opening carefully with your holder, since the overall capacity does not settle the fit question.

Choose this for the tenths scale and blue strip if its opening matches your gauge. Skip it if you need a 2.16 in diameter tube or cannot confirm the opening will seat properly.

6

BIUWING Plastic rain Gauge Replacement Tube: Best for spare tubes

8.5/10Our score

• 7 in capacity
• 2.16 in diameter
• 8.26 in height
• Plastic construction
• 2 tubes

This plastic two-pack has a 2.16 in diameter and an 8.26 in height, measurements also used by several other 7 in tubes here. Match the rim shape to your gauge.

See it on Amazon

Pros

• 2 replacement tubes
• 7 in capacity
• Stated dimensions are easy to compare

Cons

• No cleaning brush included
• Confirm rim fit

BIUWING's plastic two-pack has a 7 in capacity and stated dimensions that match several other 7 in tubes in this roundup. Its scale uses standard inch increments, and the package includes 2 replacement tubes.

Choose it if those measurements match your current tube and you want a straightforward plastic pair. Skip it if a cleaning brush is important, since this set does not include one.

7

WondMall 2PCS Rain Gauge Replacement Tube Plastic: Best for blue-strip readers

8.3/10Our score

• 7 in capacity
• Thickened plastic
• Blue strip
• 2 tubes and 1 brush
• Beveled edge

These plastic tubes have a blue strip, a beveled edge, and large-font markings. Their diameter is not specified, so compare the product illustration and your tube measurements.

See it on Amazon

Pros

• Blue strip and large-font scale
• 2 tubes and a cleaning brush
• Beveled edge

Cons

• Diameter is not specified
• Confirm the edge and opening fit your gauge

WondMall's plastic tubes combine a blue strip, large-font markings, a beveled edge, and a cleaning brush. The 7 in capacity makes it relevant to gauges designed for that range.

The diameter is not specified, so take extra care to compare the opening and bevel with your original tube. The visual features may suit your reading needs, but they cannot confirm fit.

Choose it if the strip, scale, bevel, and brush are priorities and you can confirm its dimensions. Skip it if you need published measurements before deciding.

8

Evergreen Garden Plastic Replacement Rain Gauge Tubes: Best for Evergreen owners

8.0/10Our score

• 5 in maximum measurement
• Plastic construction
• 2 tubes
• Designed for Evergreen Garden gauges
• About 1 x 1 x 5.25 in

These 5 in plastic tubes are designed for Evergreen Garden rain gauges. Their compact dimensions make brand and fit checks especially useful.

See it on Amazon

Pros

• Designed for Evergreen Garden gauges
• 5 in maximum measurement
• 2 tubes

Cons

• Brand-specific fit
• Smaller capacity than 7 in options

Evergreen Garden's pair is designed for Evergreen Garden rain gauges and measures up to 5 in. The compact tubes are about 1 x 1 x 5.25 in.

Choose this set if you own an Evergreen Garden gauge and want its brand's replacement tubes. Skip it for another brand unless your original tube and holder match these compact dimensions.

9

BIUWING 6 inch Rain Gauge Replacement Tube: Best for mid-range capacity

7.9/10Our score

• 6 in capacity
• 1.77 in diameter
• 7.08 in height
• Glass construction
• 2 tubes and 1 brush

This glass two-pack has a 6 in capacity, a 1.77 in diameter, and a 7.08 in height. Compare those dimensions with your gauge.

See it on Amazon

Pros

• 6 in capacity
• 2 glass tubes and a cleaning brush
• Dimensions are stated

Cons

• Lower capacity than 7 in options
• Check the diameter and rim fit

BIUWING's glass pair sits between the 5 in and 7 in options, with a 6 in capacity. It measures 1.77 in in diameter and 7.08 in high, and the package includes a cleaning brush.

Choose it if your gauge calls for a 6 in tube and those measurements fit. Skip it if your gauge needs a 7 in scale or a different diameter.

If your gauge is designed for 8 in capacity, read the guide to choosing an 8 inch rain gauge replacement tube before comparing this option.

Should you choose glass or plastic?

Choose glass if you prefer its material and can handle it carefully during removal, cleaning, and storage. For complete manual options, compare glass rain gauges.

Choose plastic if you want a tube whose maker describes it as less likely to freeze-crack or break.

Material is only one part of the choice. Compare the body size, opening, and rim first, then decide which material suits your yard and how you handle the gauge.

Glass tubes can be damaged by a drop or rough handling. Plastic tubes also need sensible care: avoid forcing one into a holder that seems too narrow, and inspect it if a crack or distortion makes the scale difficult to read.

How do you install and care for a replacement tube?

Install a replacement by seating it upright in the holder without forcing the rim. First remove the old tube, check for loose fragments if it broke, and clean the holder so debris does not prevent the new tube from sitting evenly.

If the gauge still misreads, see AcuRite rain gauge troubleshooting.

Set the gauge back in a stable, open spot where the collector is not blocked by a roof edge, nearby wall, or overhanging branches. Keep it upright so the scale can be read consistently, and check that the holder stays in place after you reinstall the tube.

Rinse the tube when dirt or residue makes the markings hard to see. A brush is included with several options here, but use gentle pressure, especially with glass.

Read the scale at eye level and note the increment marks before recording a measurement. Our guide on how to read a rain gauge walks through reading the water level against the scale.

What mistakes can lead to a poor fit or unclear reading?

The most common mistake is choosing by capacity alone. If you need a complete gauge rather than a replacement tube, compare wireless rain gauges.

A 7 in tube may still have the wrong diameter, opening, height, or lip for your holder.

Another mistake is measuring only the outside width. Record both outside diameter and inside opening, then note any lip or bevel that supports the tube in the gauge.

Avoid assuming every tube with the same dimensions has the same top edge. If the replacement has a lip or bevel, compare that shape with the original and the holder.

A final mistake is overlooking the scale. Standard inch increments and tenths are not the same marking pattern, so choose a scale you can read and interpret comfortably.

Which rain gauge replacement tube should you choose?

Choose JMBay's plastic 7 in tube for a readable two-pack with a brush and stated dimensions. Choose JMBay's glass pair if you want glass with a lip, or BIUWING's single glass tube if you only need one replacement.

For a shorter gauge, consider HOBYLUBY's 5 in pair or BIUWING's 6 in pair only when the opening and body dimensions match your original. Evergreen Garden's tubes are the focused choice for that brand's gauges.

Before you buy the best rain gauge replacement tube for your setup, compare height, outside diameter, opening, and rim shape. If your gauge needs 8 in capacity, use the 8 inch tube sizing guide as a next step.

Frequently asked questions

How do I choose a rain gauge replacement tube?

Measure the tube's height and diameter, then compare the opening and rim shape with the replacement. Capacity alone does not guarantee fit.

If you know the gauge's brand or model, use that information to narrow the choices, then confirm the measurements before buying.

Is a glass or plastic rain gauge tube better?

Glass suits buyers who want a glass tube and can handle it carefully. JMBay says its plastic tube is less likely to freeze-crack or break easily.

Choose by material preference, then check the tube dimensions and rim fit.

What does a lip on a glass rain gauge tube do?

A lip is a rim feature that can affect how a replacement tube sits in the outer gauge. Match the lip shape and diameter to the original tube, since a similar capacity does not confirm a secure fit.

Compare the opening and rim before ordering.

Can I use a 7 inch tube in a 5 inch rain gauge?

Only if the replacement's dimensions and rim fit the gauge, and you can read the scale correctly. Capacity labels describe measurement range, not compatibility.

Compare the tube's height, diameter, opening, and rim with your existing gauge before choosing a different capacity.

How do I read rainfall in a replacement tube?

Set the gauge upright on a level surface and read the water at eye level against the scale. Check the scale's increment marks so you know what each line represents.
