Alexander H. ★★★★★

I needed a replacement for a high-temp seal in a steam valve, and the 400°F rating on these gave me confidence. They slid on without any struggle and sealed perfectly on the first try.

Samuel L. ★★★★★

These fit perfectly on my hydraulic fittings and handled a hot oil leak that would have destroyed standard Buna-N. The 75 durometer feels substantial, and I like having the 22-pack for spares.

Hazel V. ★★★★★

Needed a reliable seal for a high-temp application and these Viton FKM o-rings fit the bill perfectly. The 75 durometer feels sturdy without being too stiff, and the 2.859" ID was exactly what I needed.
