David ★★★★★

The 70 durometer rating makes these o-rings feel sturdy yet pliable enough to seat properly without fighting you. I've used them on a few fittings around the shop and they've held up fine against the heat and cold range listed. Handy having a whole bag of 250 for the price.

Henry Z. ★★★★★

These are the exact size I need for my rebuild, and the -40°F to +250°F range gives me peace of mind for outdoor gear. The 70 durometer feels firm but pliable enough to seat properly without tearing. A solid pack of 250 for the price is hard to beat.

Natalie ★★★★★

The 70 durometer hardness is exactly what I needed for a consistent seal on my pneumatic fittings. These rings handled the 80 psi test with zero leaks.
