Sophia X. ★★★★★

Replaced the old Buna-N seals on a hot oil pump with these Viton rings and they’re holding up perfectly under continuous 350°F service. The 75 durometer feels firm but still seated easily into the grooves.

Ella D. ★★★★★

Had a small leak on a refrigeration line that these Viton o-rings sealed perfectly, and the 75 durometer feels sturdy without being brittle. With a service temp up to 400°F, they hold up great even near the compressor.

Miles U. ★★★★★

I've swapped out some worn seals in a hot oil system that kept failing, and these fit the groove perfectly with that 0.143" ID. The 75 durometer feels firm but not brittle, and they've held up for weeks now without any softening.
