4pcs Universal Gas Can Spout Gaskets - Gas Can Gaskets For 5 Gallon Plastic Gas Cans, O-Ring, Gas Rubber Fuel Can Seals Replacement Compatible with Wedco, Scepter, Midwest & More

What It Is

These are replacement rubber O-ring gaskets for the spout and cap of standard 5-gallon plastic gas cans. They seal the connection to prevent fuel leaks and vapor escape, used on any machine that relies on a portable gas can—lawn mowers, trimmers, chainsaws, etc.

Fitment & Compatibility

• Fits most 5-gallon plastic gas cans with a standard 2-inch threaded spout/cap opening, including brands like Wedco, Scepter, Midwest, and many generics.
• Check your current gasket’s inner diameter (typically ~1.5 inches) and outer diameter (~2 inches) before ordering. These are not a one-size-fits-all for smaller or odd-sized cans.
• Does not fit metal gas cans or cans with non-standard threads (e.g., some older Blitz or Eagle models). Measure your existing gasket’s thickness—these are ~3mm thick.
• Aftermarket replacement—not OEM, but works as a direct swap if dimensions match.

Key Things to Know

• Installation is simple—just remove the old gasket, clean the groove, and press the new one in. No tools needed.
• Quality varies—some users report the rubber is slightly harder than OEM, which can make seating it trickier. Soften it in warm water for a minute before installing.
• Not fuel-proof forever—these are standard rubber, not Viton, so prolonged exposure to ethanol-blended gas may cause swelling or premature wear. Expect 1-2 seasons before needing replacement.
• Pack of 4 gives you spares, but all 4 are identical—no separate cap vs. spout gaskets. If your can uses two different sizes, these won’t work.

Should You Buy It

If you have a standard 5-gallon plastic gas can with a leaky spout or cap, and you confirm the gasket dimensions match, this is a cheap, easy fix. Skip it if you have a metal can, a non-standard thread size, or want a long-term solution for ethanol gas—go with a Viton gasket instead.
