Product Overview
Gas Can Spout Gaskets (Fuel Can Seals) are specialized high-performance sealing rings designed to create a leak-proof connection between the gas can body and the pour spout. Engineered specifically for the hazardous environment of fuel storage, these gaskets prevent dangerous leaks, fumes, and spills during liquid transfer, ensuring both safety and environmental compliance.
Most standard gas can gaskets degrade quickly when exposed to modern fuels. Our replacement gaskets are manufactured from premium Viton™ (FKM) or high-grade Fuel-Resistant Nitrile (NBR), materials that maintain their seal integrity and flexibility even after years of immersion in gasoline, diesel, and ethanol blends.
Structure & Cross-Section
 |
Heavy-Duty Sealing ProfileOur gas can gaskets feature an optimized thickness and hardness (Typically 70 Shore A) to provide maximum compression without permanent deformation. The flat-face washer design ensures uniform pressure across the entire sealing surface of the spout flange, while the precision-cut inner diameter provides a snug fit that won't slip during installation. Available in standard sizes compatible with major brands like Blitz, Gott, Rubbermaid, and Wedco. We also offer custom-molded gaskets for proprietary NATO-style jerry cans and industrial liquid containers. |
Material Selection
1. Fuel-Compatible Elastomer Options
| Material | Chemical Resistance | Performance Rating |
|---|---|---|
| Viton™ (FKM) | Superior resistance to Gasoline, Diesel, Ethanol (E10/E85), and Biodiesel. | ⭐⭐⭐⭐⭐ (Longest Life) |
| Nitrile (NBR) | Excellent resistance to oils and standard gasoline. Good mechanical strength. | ⭐⭐⭐⭐ (Standard Use) |
| Fluorosilicone (FVMQ) | Extreme temperature stability + fuel resistance. Best for arctic/desert use. | ⭐⭐⭐⭐⭐ (Extreme Temps) |
| EPDM (Warning) | NOT recommended. Poor resistance to hydrocarbons; will swell and fail quickly. | ❌ (Critical Failure) |

˗ˏˋ♡ˎˊ˗FAQ – Request For Quotation
❓ Why did my rubber gasket swell and get mushy?
This typically happens when a non-fuel-resistant material (like EPDM) is used. Modern gasoline contains ethanol which is aggressive to standard rubber. Our Viton™ (FKM) gaskets are specifically designed to resist this swelling.
❓ Do these fit vintage metal Jerry Cans?
We offer specific dimensions for NATO-style metal cans. Please provide the outer diameter and thickness of your original seal for a perfect match.
❓ What is the life expectancy of a Viton gasket in daily use?
Under normal usage and exposure to standard gasoline, a Viton™ (FKM) gasket can last 5-10 times longer than a standard Nitrile (NBR) seal.
