  • Viton handles -15 °F to 400 °F temperature range

Automotive Viton O-Ring Pack

This pack contains fifty brown Viton O-rings sized to a nominal inside diameter of 7/8 inch and a nominal width of 1/16 inch. The actual inside diameter measures .8 inch and the actual width is .07 inch. They carry a 75A durometer rating for medium-hard sealing performance. The material resists temperatures from -15 to 400 degrees Fahrenheit.

Replaces Worn Inch-Series Seals

These rings suit maintenance jobs that call for dash number 020 dimensions in an inch-based system. The jump is worth it when existing seals have hardened, cracked, or swollen from heat and chemical exposure. Viton construction withstands aggressive fluids that degrade standard nitrile or silicone alternatives. Each ring is FDA approved for incidental food contact.

Handles High-Temp Fluid Sealing

The temperature range gives reliable headroom for hot oil, fuel, and coolant circuits up to 400 degrees Fahrenheit. Medium-hard durometer provides firm seating without excessive compression set. The brown colour aids visual inspection during assembly. The pack does not suit applications needing X-ray detectable or metal-detectable compounds.

Questions about this item

What groove dimensions do the 7/8 in inside diameter and 1/16 in cross-section O-rings require?

The nominal inside diameter is 7/8 in with a 1/16 in cross-section. Actual inside diameter measures .8 in and actual width .07 in, giving a nominal outside diameter of 1 in and actual outside diameter of 1.004 in.

How are these Viton O-rings installed and what common mistake should be avoided?

Lubricate the O-ring with a compatible grease, then seat it evenly in the groove without twisting. The frequent error is stretching the 1/16 in cross-section over sharp edges, which can nick the Viton material and create leak paths.

When should the O-rings be replaced given the temperature range and durometer rating?

The Viton material is rated for -15 to 400 degrees F with a 75A durometer. Replace the seals if they harden, crack or lose elasticity after prolonged exposure near the upper temperature limit or after chemical attack.
