Riley ★★★★★

Had to rebuild a pump at a chemical plant and these Viton FKM o-rings handled the high-temp steam exposure up to 400°F without any sign of degradation. The 75 durometer gave just the right firmness for the seal.

Ryan M. ★★★★★

These fit perfectly on a hydraulic cylinder I was rebuilding, the 75 durometer feels just right. The pack of 14 was plenty for the job with spares left over.

Riley F. ★★★★★

Had to swap out some old seals in a high-temp application, and these Viton FKM rings are handling the 300°F+ environment without any issues. The 75 durometer feels nice and firm, and the 3.475" ID was a spot-on fit for my flange. Exactly what I needed for the job.
