Customer Reviews (4.8 / 5 · 5 reviews)

Avery U. ★★★★★

Used these to rebuild a few pneumatic valves at work and they sealed up instantly with no leaks. The 70 durometer feels durable yet still flexible enough to seat properly in the grooves.

Nicholas D. ★★★★★

Fits perfectly into my hydraulic cylinder. The 70 durometer feels just right for the application, not too stiff and not too soft.

Olivia S. ★★★★★

These handled the -20°F temps in my unheated garage without getting brittle, and the 70 durometer seal worked perfectly in the hydraulic fitting I rebuilt. The 125-piece bag means I've got spares for every o-ring size I'll ever need.
