The best cooler drain plug replacement is the one that matches your cooler’s brand, model, and drain opening. Gnellkoor names several YETI and RTIC lines, while Igloo, Coleman, BMX, IMX, and Overland options have their own fit limits.
A replacement cap can look close and still fail to seal if its thread or wall fit differs. We compared the stated model compatibility, measurements, pack size, and included sealing parts to help you narrow the choice.

How we chose the best cooler drain plug replacements
The strongest match is the plug with clear compatibility for your cooler, not simply the one with the longest feature list. We compared the named cooler families, dimensions, sealing parts, and tether details in each option.
We gave extra weight to specific model or fit information. A broad compatibility phrase can still require checking your exact cooler, while an opening measurement helps you rule out a mismatch before ordering.
Our score weighs fit details, included parts, and how directly each option meets the needs of a cooler owner replacing a lost or damaged plug. We didn't treat these products as universal because the fit descriptions show different limits.

Best cooler drain plug replacements by fit
The best pick for your cooler depends on its drain style and model number. Check those details before ordering, especially when the plug is described for only select models.
Gnellkoor Cooler Plug Replacement for YETI: Best for YETI and RTIC compatibility
- 2 plugs
- Compatible with YETI Tundra and Roadie series, Tank ice buckets, and RTIC coolers
- Rubber cushion gasket
- Central opening for drainage
A two-plug set for several YETI and RTIC cooler lines, with a gasket and a center opening for draining without fully removing the plug.
Pros
- Names several YETI and RTIC lines
- Gasket is included
- Center opening helps retain the plug during drainage
Cons
- Check the cooler model and OEM part number before ordering
Gnellkoor is the broadest stated fit among these picks for owners of YETI Tundra or Roadie coolers, Tank ice buckets, and RTIC coolers. The pack includes two plugs, and the compatibility note references OEM part number 23010000000.
A rubber cushion gasket is part of the design. Its cross-knob head is meant to make opening easier, while a center opening lets water drain without fully unscrewing the plug, which can help keep the piece from getting lost.
This is the most useful choice here if your cooler falls within one of those named lines and you want a spare. Still, compare your cooler’s existing plug or part number before ordering, since a brand name alone doesn't confirm the fit for every model.
Yolvvetrx Black Cooler Drain Plug Replacement: Best for select Igloo BMX and IMX models
- Fits select BMX, IMX, and Overland coolers from 25–72 qt
- Stainless steel tether
- Threaded design
- Tool-free screw-in installation
A single replacement for select Igloo BMX, IMX, and Overland sizes, with a stainless steel tether to help keep the cap attached.
Pros
- Names compatible cooler families and capacity range
- Tether helps prevent cap loss
- Screw-in installation needs no tools
Cons
- Compatibility is limited to select models
Yolvvetrx is aimed at select Igloo BMX, IMX, and Overland coolers from 25–72 qt. It comes as one plug with a stainless steel tether, so it suits a replacement where keeping the cap attached matters.
The threaded design is intended to help prevent water leakage, and the screw-in installation is described as tool-free. The fit is limited to select cooler models, so check the exact cooler series and capacity rather than relying on the Igloo name alone.
This option is distinct from the Igloo threaded assembly below. Its stated compatibility focuses on BMX, IMX, and Overland sizes, and its tether is stainless steel.
Gugaguga 2 Pcs Drain Plugs Replacement: Best for a two-plug BMX, IMX, or Overland set
- 2 plugs
- Designed for BMX, IMX, and Overland 25–72 qt coolers
- Stainless steel lanyards
- Fits an approximately 1 in outer diameter drain hole and 1-1/16 in wall thickness
This two-piece set names BMX, IMX, and Overland models and gives drain-hole and wall measurements to compare with your cooler.
Pros
- Includes two plugs
- Provides fit measurements
- Lanyard connects each plug body and cap
Cons
- Not a universal cooler plug
Gugaguga offers two plugs for BMX, IMX, and Overland 25–72 qt coolers, with a stainless steel lanyard connecting each plug body and cap. The stated fit also includes an approximate 1 in outer diameter drain hole and 1-1/16 in cooler wall thickness.
Those measurements give you a practical way to check compatibility if you can measure the opening and wall. The plug uses a threaded lid and is described as a tool-free insert-and-twist installation.
Choose this set when its named cooler families and measurements match your unit and you want two replacement parts. It isn't described as a universal fit, so confirm both the cooler series and the dimensions first.
Igloo Replacement Threaded Drain Plug: Best for measured Igloo drain openings
- 2 threaded drain plug assemblies
- Rubber gasket, plastic washer, and plastic nut
- Fits about 1 in outer diameter drain holes and 1-1/16 in wall thickness
- Plastic tether helps prevent cap loss
An Igloo-made two-pack with a full threaded assembly, but it fits only coolers matching the stated drain-hole and wall measurements.
Pros
- Includes gasket, washer, nut, and tethered cap
- Provides hole and wall measurements
- Threaded cap
Cons
- Not universal across Igloo coolers
The Igloo assembly is the clearest choice for an Igloo cooler that matches the stated hole and wall dimensions. The two-pack includes a main body, tethered threaded cap, rubber gasket, plastic washer, and plastic nut.
Its stated fit is an outer drain-hole diameter of about 1 in and cooler wall thickness of about 1-1/16 in. Igloo cautions that this is not a universal replacement for its coolers because other sizes are available.
Compare those measurements with your cooler before ordering. If your old assembly is intact, use it to identify the needed parts and shape; if not, check the cooler model and drain opening.
Amzlysdok 2PCS Coleman Cooler Drain Plug Kit: Best for listed Coleman model numbers
- 2 plugs
- Names 28 Coleman model numbers
- Part number R5214D607G
- Threaded design with gasket
A two-plug kit for the Coleman model numbers it names, with a threaded fit and gasket. Match your cooler model before choosing it.
Pros
- Names compatible Coleman model numbers
- Includes two plugs
- Gasket and threaded design
Cons
- Compatibility depends on matching a named model
Amzlysdok is the Coleman option here, with two plugs and a list of compatible model numbers that includes 5227, 5235, 5239, 5240, and many others through 6270. The kit references Coleman part number R5214D607G.
Its threaded design and gasket are intended to help seal the drain, and installation is described as tool-free. Since the fit is tied to a set of Coleman models, compare your model number with the stated list before choosing this kit.
Use this option when your Coleman cooler’s model number matches. If you can't find it, check the existing plug or contact the cooler maker for the right replacement part number.
How to check a cooler drain plug fit
A cooler drain plug replacement should match the opening, threading, and wall depth of the original assembly. Use the model number and old part as your first clues, then compare measurements where the replacement provides them.
What should you measure before ordering?
Start with the outer diameter of the drain opening and the cooler wall thickness. Some options here give measurements around 1 in for the opening and 1-1/16 in for the wall, but those figures don't apply to every cooler plug.
If you still have the old part, compare the threads, cap shape, gasket, and any tether. A photo can help you compare the replacement’s design, but measurements and model compatibility are more reliable.
Does a tether matter?
A tether helps keep a cap attached to the cooler when you open it. Yolvvetrx specifies a stainless steel tether, while the Igloo assembly uses a plastic tether; Gugaguga also includes a stainless steel lanyard.
If the cooler often gets drained outdoors, a tether may reduce the chance of misplacing the cap. It doesn't replace checking thread and gasket fit.
Choosing between a cap, plug, and full drain assembly
Some replacements are simple plugs, while others include several parts that attach through the cooler wall. Check what the original assembly needs before deciding between a cap-only replacement and a kit.
The Igloo set includes a gasket, washer, nut, body, and cap. By contrast, the Gnellkoor option emphasizes a center drainage opening, while the Coleman kit focuses on replacement plugs for named models.
For installation steps, use our guide on how to install a drain plug in a cooler. If the cooler itself is still on your shortlist, best small coolers with drain plugs covers compact options.
What to do if a replacement cooler drain plug leaks
A leak after installation usually calls for a fit and seal check. Confirm that the plug matches the cooler, sits squarely, and has its gasket or other required sealing parts in place.
Avoid forcing a mismatched thread, since that can damage the opening or prevent a tight seal. Empty the cooler, dry the area, reinstall according to its instructions, and check for leaks before loading ice or food.
A drain plug handles water release, while a cooler zipper serves a different job. If you're maintaining an RTIC cooler, see our guides to RTIC cooler zipper lubricant and RTIC cooler zipper replacement.
Final pick for a cooler drain plug replacement
Choose Gnellkoor when your YETI or RTIC model matches its stated compatibility, and choose the Igloo or Coleman option only when your model and fit details line up. For BMX, IMX, or Overland coolers, compare the capacity and dimensions before deciding between the one-plug and two-plug options.
A secure drain matters most when you carry ice and meltwater, so test the seal before a trip. For more cooler context, read our YETI Tundra 35 review and compare cooler ice packs for keeping contents cold.
A replacement cooler drain plug is a small part, but the right fit depends on details. Match the cooler model, opening, and seal before ordering.

Frequently asked questions
How do I choose a cooler drain plug replacement?
Match the cooler brand and model first, then compare the drain opening and wall thickness if those measurements are available. A plug that fits one cooler in a brand family may not fit every model.
Check the old plug’s part number or measure the opening before ordering.
Are cooler drain plugs universal?
No. Cooler drain plugs can differ by thread, opening size, wall thickness, and plug design.
The Igloo replacement, for example, is specified for an opening about 1 in across and a wall about 1-1/16 in thick, and it is not universal across Igloo coolers.
Confirm the fit for your exact model.
Can I use a YETI cooler plug on an RTIC cooler?
The Gnellkoor plug is described as compatible with YETI Tundra and Roadie coolers, Tank ice buckets, and RTIC coolers. Check your exact model and the OEM part number before ordering because compatibility can vary across a brand’s range.
A similar-looking plug does not confirm a matching seal.
How can I tell whether a replacement plug will seal?
Check that the replacement matches the drain’s thread and dimensions, and confirm that its gasket or sealing parts are included. Tighten it as directed and check for leaks before filling the cooler for a trip.
Replace worn or damaged sealing parts if the plug still leaks.
