Brian ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure seal, and at 500 per package, I’ve got plenty of spares for future jobs. The sizing is spot-on to spec, and they arrived in perfect shape, no warping or deformation.

Evelyn B. ★★★★★

I needed a bulk pack for a hydraulic repair job, and the 90 durometer held up perfectly under constant pressure. These 0.139” cross-section rings seated easily and showed no swelling after exposure to oil.

Amelia ★★★★★

The 90 durometer feels noticeably firmer than the standard ones I've used, which is exactly what I needed for a higher-pressure seal. They fit the groove perfectly and arrived well-packed in the resealable bag.
