Customer Reviews (4.4 / 5 · 5 reviews)

Grace ★★★★★

Swapped these into a hydraulic line that runs hot all day and they’ve held up without any softening or deformation, which is exactly what I needed from the 250°F rating. The 70 durometer feel is stiff enough to seat firmly but still easy to work into the groove.

Benjamin Q. ★★★★★

The 7.234" inner diameter fit perfectly on my air compressor filter housing, and the 70 durometer rubber feels dense enough to handle the 100 psi without any leaks.

Miles ★★★★★

The cross-section on these o-rings is exactly 0.139" as listed, and they fit snugly in my hydraulic repair job. The 70 durometer feels just right for the compression needed.
