Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

Was replacing some old gaskets on a hydraulic pump and these X-rings fit the groove perfectly. The 70 durometer feels spot on for the application and the package of seven gave me extras for the next repair.

Mia ★★★★★

The 400°F rating is what sold me, and these Viton rings handled the heat without any hardening or cracking. The 0.139" cross-section sits snug in the groove of my pump flange, and the 7-pack means I've got spares for next time. Exactly what I needed.

Stella V. ★★★★★

I needed a high-temp seal for a hydraulic press and these Viton FKM rings handled the 350°F operating temperature without any issues. The 3.859" inner diameter fit perfectly into the groove.
