Scarlett ★★★★★

Replaced the worn seals in my garden sprayer and these -40°F to +250°F rated rings handled the hot water flush without a hint of softening. The 70 durometer hardness feels just right—firm enough to seat snugly but not so stiff they crack when I stretch them over the groove.

James F. ★★★★★

These fit perfectly in my hydraulic cylinder rebuild kit and the 70 durometer feels like the right firmness for the job. Used a few already with no leaks at moderate pressure.

Thomas W. ★★★★★

I was worried about finding the right size for my air compressor fittings, but the dash 053 designation made it easy to match. The 70 durometer feels like the right firmness for a reliable seal, and the pack of 30 should last me a while.
