Precision O-Ring for 82 mm Sealing Applications
This Viton O-ring delivers a reliable seal with an 82 mm inside diameter and 4 mm cross-section. The material handles temperatures from -15 to 400 degrees Fahrenheit. A medium-hard 75A durometer resists extrusion in static and dynamic joints. Black colour aids visual inspection during assembly.
Suited for Chemical and High-Temperature Duties
Engineers specifying fuel, oil or solvent systems will value the Viton compound. Buyers needing FDA-compliant seals for food contact should look elsewhere. The metric sizing suits standard groove designs, but non-standard diameters require a different ring.
Supplied as a Single Seal Only
No lubricant, installation tool or spare rings are included. The metal-detectable additive helps quality-control scanners locate fragments in processing lines. X-ray inspection systems will not detect this material. California Proposition 65 labelling applies to the compound.

Questions about this item
Does the 82 mm inside diameter match the groove on my existing flange?
The ring has an actual inside diameter of 82 mm and an actual outside diameter of 90 mm, so it fits a groove cut to those metric dimensions.
Will the Viton material handle the same temperatures as the Buna-N seals I am replacing?
This Viton ring is rated from -15 °F to 400 °F, which is a wider range than standard Buna-N and suits most oil, fuel and chemical services.
How can I verify the seal is seated correctly after installation?
Check that the black 4 mm cross-section sits uniformly in the groove with no visible twist, and pressure-test the assembly — no leakage confirms proper seating.
