Customer Reviews (5.0 / 5 · 5 reviews)

Nicholas ★★★★★

These hit the perfect fit for my Parker fittings. The 70 durometer is soft enough to seat easily but seals tight against 200 psi air. A solid pack for the price.

Joseph ★★★★★

I've been using these for a hydraulic line repair and the 70 durometer feels firm yet still seals smoothly. They fit the groove exactly as expected, and the temperature range covers everything I need in the shop.

Leo T. ★★★★★

These fit perfectly on my 2-inch NPT fittings and the rubber feels much more substantial than the cheap hardware store ones I've been using. Even after sitting in hot transmission fluid for weeks they haven't hardened up at all.
