Joseph X. ★★★★★

I needed o-rings that could handle high heat near my engine, and these Viton FKM ones with a 400°F rating are perfect. The 2.424" inner diameter fit snugly without any struggle. They’ve been holding up great after a week of use.

Sofia ★★★★★

These seals fit perfectly on my heat exchanger flanges and the 75 durometer is firm enough to handle the higher torque without squishing out. I’ve been running them at 350°F cycles with no signs of degradation yet.

Zoe ★★★★★

Installed these on a hydraulic fitting that sees constant heat cycles, and they sealed perfectly on the first try. The brown color is nice for identifying them in the kit, but more importantly, the 75 durometer feels just right—firm enough to hold pressure without being brittle.
