Olivia ★★★★★

Installed these 325 o-rings on an air compressor fitting that kept leaking—the 50 durometer rubber grabbed the groove perfectly without being too stiff. The -40°F capability gives me peace of mind for winter use. Felt like a solid value for the 60-pack too.

Joseph ★★★★★

I needed a reliable seal for a hydraulic fitting that sees temps down to -40°F, and these o-rings have been holding tight without any hardening. The 1.475" ID fits perfectly onto the groove I measured.

Avery J. ★★★★★

The 50-durometer rubber gives these a nice pliable feel without being flimsy, and they slid right into my pneumatic fittings. Great price for a pack of sixty.
