Daniel ★★★★★

These HNBR o-rings held up perfectly in a high-temp gearbox application where standard Buna-N ones would crack. The 80 durometer feels firm enough to maintain a seal, and they fit the groove snugly. Exactly what I needed for the job.

Evelyn D. ★★★★★

Swapped out the old standard nitrile seals for these HNBR ones on a coolant line, and they’ve held up perfectly even with the higher temperatures. The 0.139" cross-section feels a bit stiffer than I expected, but that 80 durometer gives a nice, snug seal.

Stella P. ★★★★★

Used these on a hydraulic fitting that sees temps around 250°F and they’ve held up perfectly without any hardening. The -40°F rating gives me confidence for winter storage too.
