Gasoline Cans Seals for Jerry Cans, USMC Blitz Metal Gasoline Cans, Gas Cans/Flexible Nozzles/Can Spout for 5 Gallon/20L Leak-Proof Rubber Seals 6 Pack

What It Is

This 6-pack of leak-proof rubber seals replaces the gaskets inside the cap or spout of 5-gallon/20-liter metal jerry cans, specifically those used with USMC-style military cans, Blitz metal gas cans, and similar flexible nozzle or spout assemblies. They stop fuel spills and vapor leaks on lawn mowers, tractors, and other small engines.

Fitment & Compatibility

Before buying, measure the inner diameter of your can’s cap or spout opening. These seals fit standard 2-inch openings common on USMC and Blitz metal cans but may not work with plastic cans or newer “safety” cans with proprietary caps. Check if your can uses a single rubber gasket or a two-piece seal (cap + spout)—this pack covers both. Not compatible with VP Racing or NATO-style cans without verifying dimensions. OEM vs aftermarket: these are universal aftermarket replacements, not branded OEM parts.

Key Things to Know

• Quality: Soft rubber that compresses well, but some users report mild shrinkage after long exposure to gasoline. Inspect annually.
• Installation: Easy—remove old seal, clean surface, press new one in place. No tools needed. Takes 2 minutes per can.
• Gotcha: Do not overtighten the cap or spout; it can distort the seal and cause leaks. Hand-tight only.
• Pack size: Six seals let you service multiple cans or keep spares. Good for a small fleet.

Should You Buy It

Buy if you own a USMC-style or Blitz metal 5-gallon jerry can with a leaking cap or spout, and you want a cheap, quick fix for fuel spills on your mower or tractor. Skip if you have plastic cans, NATO cans, or need OEM-specific seals for a new safety can.
