Customer Reviews (4.6 / 5 · 5 reviews)

Jason Y. ★★★★★

Needed to replace some old seals on a high-temp pneumatic valve, and these Viton rings handled the 350°F steam exposure without any sign of softening or cracking. The 75 durometer feels just right for a snug fit without being too hard to install.

Carter ★★★★★

Used these o-rings on a hydraulic fitting that runs around 350°F, and the Viton material hasn't degraded at all after a month of daily use. The 75 durometer gives a firm but compressible feel when seated. Exactly what I needed for high-heat applications.

Chloe S. ★★★★★

Needed a reliable seal for a high-temp hydraulic line, and these Viton o-rings fit the dash 312 groove perfectly. The brown color makes them easy to spot against standard black rubber, which is a nice bonus for maintenance checks.
