Avery E. ★★★★★

I needed a high-temp seal for a steam line, and these FKM o-rings hold up beautifully at 400°F without any hardening. The 75 durometer gives them a firm but not brittle feel during installation.

Amelia U. ★★★★★

The 4.234" inner diameter fit perfectly on my hydraulic pump flange, and the Viton material handled the 350°F steam without any softening. These brown rings are exactly what I needed for a reliable seal.

Sophia S. ★★★★★

Used these to fix a high-temp oil leak on my compressor and they fit perfectly. The brown color made them easy to spot against the metal housing. So far holding up great at 350°F.
