Natalie ★★★★★

I had a feeling these would work after checking the durometer and temp range, and they seated perfectly in my hydraulic cylinder without any leaks. The bag of 300 will last me years of rebuilds.

Julian ★★★★★

I needed a bulk supply to rebuild a pneumatic system, and these 2.549" ID Buna-N rings fit perfectly with the 0.103" cross-section. They seated well without any binding, and the rubber held up fine at 180°F operating temp.

Sebastian ★★★★★

The 70 durometer is just right for my air fittings — seals tight without being hard to press into place. A full 300-pack at this size should last me years of tinkering.
