Sofia R. ★★★★★

The 0.21" cross-section feels substantial and precise; I used these to rebuild an older pneumatic press. They seated perfectly in the groove without any twisting, and the 70 durometer handles 90 PSI without complaint.

Evelyn E. ★★★★★

These o-rings fit my hydraulic cylinder perfectly with a tight, even seal. The 70 durometer is firm but still flexible enough to work into the groove, and the service temperature range gives me confidence for the job.

Daniel ★★★★★

Swapped out the old worn seals on a big hydraulic cylinder and these fit the groove perfectly, that 14.475" ID is spot on. The 70 durometer rubber feels firm but has just enough give to seat without fighting. Glad I grabbed the 20-pack since I need a few spares for next time.
