Joseph Y. ★★★★★

These o-rings seated perfectly in a hydraulic fitting I was repairing, and the 50 durometer made them much easier to work with than the harder ones I've struggled with before. The 100-piece pack gives me plenty of spares for future jobs.

Leo ★★★★★

The 50 durometer is noticeably softer than the standard 70, which made installation on a delicate plastic fitting much easier without cracking anything. Fit the groove perfectly and seals tight so far.

Ruby G. ★★★★★

Been using these for a hydraulic repair job and the 50 durometer gives just enough flexibility to seat perfectly without tearing, even at 30°F shop temps. The 1.984" ID fit snug on the shaft first try, saving me from digging through the bin again.
