Brian ★★★★★

Installed these on a hydraulic cylinder repair I’ve been putting off, and the -40°F to 300°F temp range gives me confidence they’ll hold up in both winter and summer. The 0.139" cross-section fit the groove perfectly.

George M. ★★★★★

The 70 durometer feels just right for my hydraulic application—not too stiff, not too soft. I've used them in a continuous 250°F environment and they haven't hardened or cracked after a month of service.

Isabella E. ★★★★★

These handled the heat cycling on my air compressor manifold without any sign of hardening or cracking. The fit was snug right out of the bag, exactly what I needed for that 0.921" ID groove.
