William ★★★★★

The 50 durometer softness is perfect for a low-pressure seal where I needed a bit of give without the thing popping out. This size is awkward to find locally, so getting a full 200-pack in the standard AS568-141 spec is a big win for the workshop.

Adam C. ★★★★★

Not as stiff as the 70-durometer ones I usually grab, and that softer 50 rating made seating them in a stubborn hydraulic flange a breeze. The 2.299" ID matched the groove perfectly, and I've got a full 200-count box to work through—at this price, I'm stocked for a couple years.

Chloe ★★★★★

These 50-durometer o-rings seated perfectly in my pump housing, and the cross-section thickness felt exactly right for the groove depth. I appreciate that the material stays flexible down to -40°F, since my equipment sits in an unheated garage all winter.
