Scarlett P. ★★★★★

The 0.139" cross-section fits perfectly into my pneumatic cylinder groove, and the 70 durometer feels just right for the seal I needed. These arrived well-packaged and have held up without any leaks in the first week of use.

Ellie ★★★★★

Installed these in a hydraulic fitting on my log splitter and the square profile really holds steady under pressure. The 70 durometer feels just right for this application, not too stiff or soft.

Scarlett Y. ★★★★★

The square profile on these o-rings seated perfectly in the groove on my hydraulic cylinder, no rolling or twisting during installation. They're the exact 70 durometer I needed for a firm seal without being too hard to compress.
