Customer Reviews (4.2 / 5 · 5 reviews)

Stella ★★★★★

These arrived in a sturdy box and the 70 durometer hardness feels exactly right for the valve rebuild I was doing. The 1.224" inner diameter seated perfectly on the piston, and the black color looks uniform across all 100 pieces.

Alexander X. ★★★★★

I needed a batch of these for a hydraulic seal repair on an old press, and the 0.21" cross-section fit perfectly into the groove. They seated smoothly without twisting, and the rubber feels dense enough to handle the 200°F oil temps.

Hazel ★★★★☆

The 70 durometer hardness feels just right for my application, and the 1.224" ID seated snugly without any wrestling. Handling a hundred of these in one pack is convenient for future repairs. Only wish the package had a resealable bag, but that's a minor gripe.
