Customer Reviews (4.6 / 5 · 5 reviews)

Carter ★★★★★

These handled the hot oil in my deep fryer perfectly without any leaking or deformation. For the price of a 25-pack, it's a solid deal for anyone needing high-temp seals.

Ellie N. ★★★★★

I needed a reliable seal for a hydraulic clamp that sees constant pressure, and these o-rings fit perfectly without any deformation after a week of use. The 75 durometer feels just right—not too stiff, not too soft—and the brown color makes them easy to spot during assembly.

Eli X. ★★★★★

These handled the 400°F heat cycling on my hydraulic press without any sign of hardening. The 75 durometer feels just right for a snug seal without being impossible to install.
