10PCS Gas Can Vents for Plastic Gas Cans, Gas Can Spout Replacement, Flexible Pour Nozzle Gasket Stopper Vent Cap Collar Caps, Yellow Fuel Gas Can Vent/Cap for Most Old Style Gas Water Jug

What It Is

This is a 10-pack of replacement vents, caps, and gaskets for old-style plastic gas cans (typically yellow or red utility jugs). They fit standard 1–5 gallon cans with a rigid spout or pour nozzle, not modern CARB-compliant or safety-spout cans.

Fitment & Compatibility

Before buying, check these three things:

• Thread type & size: These vents are designed for the common 1-inch (25mm) internal thread found on most old-style gas cans. Measure your can’s vent opening diameter—if it’s smaller or larger, these won’t seal.
• Can style: Works only with old-style cans that have a separate vent cap (not integrated into the spout). Not for newer “no-spill” or push-button spout cans.
• Material compatibility: The yellow plastic is for gasoline only. Do not use with diesel, kerosene, or water jugs—the gaskets may degrade.

Key Things to Know

• Quality: The yellow plastic is lightweight but durable for occasional use. The stopper/gasket seals well if the can’s threads are clean and undamaged.
• Installation: Very easy—unscrew old vent, screw in new one. No tools needed. The flexible pour nozzle gasket is a bonus for sealing leaky spout bases.
• Common gotcha: If your can’s vent hole is cracked or warped, these won’t fix the leak. They also won’t fit newer “safety” cans with a built-in pressure release valve.
• Pack quantity: You get 10 pieces—good for multiple cans or spares, but check if you need only one or two.

Should You Buy It

Buy this if you have an older plastic gas can (pre-2010) with a loose or missing vent cap and you want a cheap, quick fix. It’s ideal for small engines like lawn mowers, trimmers, or generators. Skip it if you need a vent for a modern CARB-compliant can or a metal gas can—those require different threads or materials.
