Customer Reviews (4.4 / 5 · 5 reviews)

Robert X. ★★★★★

I grabbed these for a pneumatic application where standard buna-n was failing, and the Viton held up perfectly even with occasional heat spikes. The 75 durometer feels just right—stiff enough to stay seated but still easy to install in the groove.

Richard P. ★★★★★

I needed a high-temp seal for a hot oil line, and these Viton FKM rings with the 75 durometer feel like they'll handle the job perfectly. The 4.234" inner diameter was an exact match for my application.

Michael ★★★★☆

These sealed perfectly on the hydraulic fitting I needed them for, and the 4.234" ID was exactly as listed so no guesswork. Took off one star only because the package doesn't include a spare or two, but the Viton material feels like it'll hold up fine.
