Customer Reviews (4.8 / 5 · 5 reviews)

Samuel ★★★★★

These replaced the standard Buna-N seals on my pressure washer pump, and the FKM material handles the heat buildup without getting brittle. The brown color makes them easy to spot against the steel parts during assembly.

Stella ★★★★★

I needed o-rings that could handle high heat near a boiler, and these Viton FKM ones with their 400°F rating fit the bill perfectly. The 1.984" ID matched my application exactly, and the brown color made them easy to spot during installation.

Jacob L. ★★★★★

I was replacing o-rings on a hydraulic cylinder and the -15°F low temperature spec gave me confidence they'd hold up. The 75 durometer feels firm enough for the seal but still flexible to install.
