Customer Reviews (4.6 / 5 · 5 reviews)

Owen ★★★★★

Just replaced the seals in my hydraulic press with these and they fit perfectly—the 75 durometer feels solid without being too stiff. Nice to have a 55-pack so I’ve got spares for future projects.

John Y. ★★★★★

I work on a lot of hot oil systems and these o-rings seat perfectly with no leaks, even after repeated thermal cycles. The 75 durometer gives just enough stiffness to hold position during installation without cracking.

Michael ★★★★★

The high-temp rating on these o-rings is perfect for my compressor rebuild—they seal better than the old standard Viton ones I used before. The 75 durometer feels just right for a snug fit. This pack will last me through several projects.
