Lily I. ★★★★★

The 75 durometer brown Viton rings fit perfectly into my hydraulic fitting groove and the -15°F to +400°F range is exactly what my hot oil system needed. The 3.109" ID seated snugly with no distortion, and the package of 30 means I've got spares for the next rebuild.

Daniel ★★★★★

I needed o-rings that could handle high-temp applications and these Viton FKM ones arrived quickly, the 75 durometer feels solid and they seated properly on first try without any deformation.

Eva L. ★★★★★

These have been holding up perfectly in a high-temp application near a furnace where standard Buna-N would have melted in a day. The brown FKM material feels noticeably more pliable than I expected for a 75 durometer.
