Customer Reviews (5.0 / 5 · 5 reviews)

Hazel E. ★★★★★

The material feels noticeably more pliable than standard Viton, yet the 75 durometer holds up perfectly under my 350°F steam line. Installation was straightforward, and the 5.484" ID matched my flange groove without any struggle.

Sofia ★★★★★

These o-rings fit my hydraulic cylinder perfectly and the 75 durometer feels just right for the application. I'm glad I went with the Viton FKM material given the 400°F rating.

Isabella ★★★★★

I needed o-rings that could handle high heat, and the 400°F service range on these Viton ones fits the bill perfectly. The 75 durometer feels sturdy enough for my application, and the seal is holding tight so far.
