Customer Reviews (4.2 / 5 · 5 reviews)

Alexander W. ★★★★★

These replaced a worn-out seal on a hydraulic press and the fit was perfect right out of the package. The 80 durometer hardness feels substantial and I'm confident they'll handle the 300°F operating temperature we need.

Ava S. ★★★★★

Was a bit nervous about finding the right o-ring for a high-temp hydraulic line, but these HNBR seals fit the 8.475" ID perfectly and the 80 durometer feels just right. They've been holding up great in the 200°F range so far.

Mia ★★★★☆

The 8.475" inner diameter was a perfect fit for my hydraulic cylinder, and the 80 durometer feels plenty firm for the pressure. I just wish the package had a few more rings for the price.
