Leo O. ★★★★★

The 90 durometer hardness on these is exactly what I needed—they seat firmly without squishing out of the groove during assembly. And at 400 per pack, I've got spares for every future fitting without stressing about running out.

Jacob Z. ★★★★★

Ordered these for a rebuild and the 90 durometer felt noticeably stiffer than the standard 70s I’d used before, which is exactly what I needed for a high-pressure seal. They fit the groove perfectly at 1.359" ID and the -40°F to 250°F range covers my application without worry. Glad I bought the 400-

Charlotte D. ★★★★★

The 90-durometer hardness is perfect for high-pressure applications in my hydraulic gear. The fit on the 1.359-inch inner diameter was spot-on with my equipment, and the pack of 400 will last me years.
