Customer Reviews (4.4 / 5 · 5 reviews)

Scarlett ★★★★★

I needed a precise fit for a high-temp pneumatic seal, and the 90 durometer on these is just right. They arrived well-packed and the 500 count is fantastic for the price.

Benjamin L. ★★★★★

The 90 durometer is noticeably stiffer than the 70 I'd been using, which is exactly what I needed for a high-pressure pneumatic setup. These fit perfectly on a standard SAE fitting and the nitrile material feels tough and reliable.

Elizabeth ★★★★★

I needed a bulk supply of o-rings for a hydraulic repair job, and these 90-durometer Buna-N rings fit the AS568-217 spec perfectly. The 500-count pack is a great value for the price.
