Customer Reviews (4.8 / 5 · 5 reviews)

George ★★★★★

Installed these on a hydraulic press seeing 350°F and the brown FKM material hasn't cracked or softened after a few weeks. The 75 durometer feels just right—stiff enough to hold pressure but flexible to seat.

Matthew ★★★★★

Needed a large o-ring for a high-temp application and this 9.475" inner diameter Viton one fit perfectly. The brown color even makes it easy to spot during maintenance.

Ellie I. ★★★★★

The 75 durometer feels just right for my hydraulic repair job — firm enough to seal without being a struggle to install. These Viton rings held up perfectly to the 350°F operating temperature I’m dealing with. No leaks after a week of constant use.
