Customer Reviews (5.0 / 5 · 5 reviews)

Timothy G. ★★★★★

These fit perfectly on my air compressor fittings and the 70 durometer feels like the right firmness for a good seal. The temperature range was exactly what I needed for my application.

Daniel ★★★★★

Used these to rebuild a hydraulic cylinder on my tractor, and they sealed perfectly even under high pressure. The 70 durometer feels firm but not brittle during installation.

Claire T. ★★★★★

Put these on my compressor's check valve and the fit was spot on—the 70 durometer feels firm but not brittle. No more air loss, and they handle the heat from the pump just fine.
