4pcs Blitz Gas Can Vents For Plastic Gas Cans - Plastic Gas Can Vent Caps Replacement, Gas Can Breather Vent Kit, Fuel Vent Caps For Gas Cans Suitable ForPlastic And Metal Fuel Jugs

What It Is

These are replacement vent caps for gas cans, designed to equalize air pressure inside the can as fuel is poured, preventing glugging and spills. They fit standard plastic and metal fuel jugs, not lawn mower engines themselves.

Fitment & Compatibility

• Check your gas can’s vent hole diameter – these caps fit most standard 1/2-inch to 3/4-inch openings, but measure yours before ordering.
• Works with common plastic gas cans (e.g., Blitz, No-Spill, SureCan, VP Racing) and metal military-style jugs. Not for use on fuel tanks on mowers, trimmers, or blowers.
• OEM vs aftermarket – these are generic replacements, not OEM. If your can uses a proprietary thread or bayonet-style vent, these may not fit.
• Material – plastic caps with a brass or nylon breather valve. Avoid using with ethanol-blended fuels if the valve is not alcohol-resistant (check product description).

Key Things to Know

• Installation – just unscrew the old vent and screw in the new one. No tools needed, but don’t overtighten or you may crack the cap.
• Quality – many users report they seal well and prevent leaks, but a few note the plastic can crack in freezing temperatures. Store cans indoors.
• Common gotcha – if your can has a separate cap and vent (like a twist-off cap with a push-button vent), these won’t replace the cap itself. They’re only for cans with a dedicated vent hole.
• Compatibility with metal cans – the threads on metal jugs may be coarser; test fit before fully tightening. Some metal cans require a rubber gasket (not included).

Should You Buy It

If your gas can’s original vent is cracked, missing, or leaks, these are a cheap and easy fix. They’re best for standard plastic cans with a threaded vent port. For odd-sized or proprietary vents, measure first or look for a specific OEM replacement.
