Customer Reviews (4.8 / 5 · 5 reviews)

Madison ★★★★★

These o-rings fit perfectly on my pump’s flange that sees continuous hot water, and the Viton material feels much more resilient than the standard rubber ones I’ve used before. The 75 durometer hardness seems just right for keeping a tight seal without being too stiff.

Kevin ★★★★★

Replaced a leaky rubber gasket in a hot-oil line and these Viton rings haven’t so much as softened after weeks at 350°F. The 75 durometer feels firm but not brittle, and the brown color makes them easy to spot during inspection. Nice that a 40-pack covers mistakes and future swaps.

Mia S. ★★★★★

The 1.349" inner diameter fit perfectly on my hydraulic cylinder. Handled the 400°F rating without any issues during testing.
