Customer Reviews (4.0 / 5 · 5 reviews)

Mia E. ★★★★★

The 70 durometer compound has just the right amount of flex for sealing my hydraulic cylinder, and they slid into place without any force. No leaks after a week of use.

Emma ★★★★☆

Finally got these to replace a worn seal on a 10-inch flange; the 70 durometer feels solid but not too stiff. Fit was spot on, though I wish the package had a few more for that price.

Penelope P. ★★★★☆

Needed these for a hydraulic cylinder rebuild and the 70 durometer is just right for the low-pressure seals. The inner diameter is exactly 10.475" as stated, so they seated snugly. Only wish the package had a few more spares for the price.
