Adam Y. ★★★★★

Installed these on a water manifold at work and the 70 durometer made them easy to seat without deforming. The -40°F rating gives me confidence for our outdoor equipment in winter.

Benjamin ★★★★★

Packed five of these onto a hydraulic fitting last week, and the 2.234" inner diameter was a perfect match for the groove. Handled the 250°F operating temp without any softening or deformation.

Ava ★★★★★

The 70 durometer is just right for the hydraulic line repair I was doing, and the -40°F rating gives me peace of mind for outdoor use. These 228-sized rings fit the groove perfectly and the bag of 125 will last me through several projects.
