O-Rings

Holley O-rings (part number 26-37) are precision rubber seals specifically designed for use in Holley carburetors and fuel systems. These seals are essential for maintaining fuel system integrity, preventing leaks that can compromise performance and safety. Whether you're working on a classic muscle car or a modern street machine, these O-rings are crucial for reliable fuel delivery.

Manufactured from durable fuel-compatible elastomer compounds, these O-rings are engineered to withstand exposure to fuel, temperature fluctuations, and consistent pressure cycling without degrading. The precise dimensional tolerances ensure a snug fit, creating a complete seal without the risk of over-compression that could lead to material failure. Holley's OEM-spec design ensures compatibility with various fuel types, including gasoline and ethanol blends.

Carburetor enthusiasts and performance shops rely on these seals during restoration and modification work. They are particularly important when replacing worn fuel bowls, fuel inlet fittings, or power valve assemblies on Holley carburetors. Keeping multiple sets on hand during a full carb overhaul is advisable to avoid reusing old, compressed seals that may have lost their sealing properties.
