The -08 Viton O-Ring from REDHORSE PERFORMANCE is a critical sealing component designed for high-performance automotive fuel and fluid systems. Packaged as two pieces per set, this -08 sized o-ring is essential for mechanics and engine builders who demand reliability in custom fuel lines, carburetor bowls, intake manifold passages, and transmission cooler circuits. Whether you're assembling a street machine, restoring a classic, or tuning a forced-induction platform, proper sealing at fluid connections prevents catastrophic leaks under pressure and temperature cycling.
Viton (fluoroelastomer) construction is the gold standard for automotive applications because it resists fuel, oil, coolant, and transmission fluid while maintaining elasticity across extreme temperature ranges—critical when boost or nitrous systems elevate underhood conditions beyond stock parameters. The -08 designation refers to the industry-standard AN (Army-Navy) size, meaning this o-ring fits JIC and AN fittings with -08 bore specifications. Viton's superior chemical compatibility and thermal stability at 400°F+ make it far more durable than inferior rubber compounds, especially in carbureted or fuel-injected engines where fuel system pressure and heat demand proven materials. Two o-rings per package ensure you have a backup for installation mistakes or future service intervals.
This product is ideal for fabricators, restoration specialists, and weekend warriors building custom fuel delivery systems, EFI conversions, or high-performance carburetor manifolds. Use these o-rings when connecting -08 AN fittings to fuel rails, carb adapters, filter housings, or transmission lines; always apply a thin layer of compatible grease to the o-ring before installation to ensure a leak-free seal. REDHORSE PERFORMANCE o-rings are trusted by professional shops and serious enthusiasts because they eliminate guesswork—Viton eliminates future leaks and the risk of fuel pooling in engine bays. Verify your fitting size (measure or count port threads) before ordering to ensure correct fit and optimal sealing performance.
