Eli ★★★★★

Needed a replacement set for a high-temp hydraulic application and the -15°F to +400°F range on these is exactly what I needed. Fit perfectly on the fitting, and the 75 durometer feels just right.

Ella L. ★★★★★

Used these on a steam valve that's been leaking for months. The 400°F rating gives me peace of mind, and the 0.21" cross-section fit perfectly in the groove.

Ruby ★★★★★

Had to replace a seal on a high-temp pump and these 75 durometer FKM o-rings fit the groove perfectly. The 0.21" cross-section is noticeably thicker than the old one, so this repair should hold up for a while.
