Christopher P. ★★★★★

I've got a machine that chews through cheaper o-rings in weeks, but these 90 durometer ones are holding their shape perfectly after a month of constant 200°F service. The 2.049" inner diameter fit snug on the first try, no stretching or wrestling. For 400 pieces at this price, I'm set for years.

Nicholas ★★★★★

The 90 durometer stiffness is exactly what I needed for a high-pressure application, and the 2.049" inner diameter fit the groove perfectly on the first try. Four hundred in the bag means I’ve got spares for every future rebuild, and they handled the 250°F range without a hint of softening.

David V. ★★★★★

These 90 durometer o-rings sealed a stubborn leak on my old air compressor where softer ones had failed. The pack of 400 is great value for the price, and the -40°F rating gives me confidence for outdoor winter use.
