Customer Reviews (4.8 / 5 · 5 reviews)

Harper L. ★★★★★

The 4.225" inner diameter was a perfect match for my hydraulic cylinder, and the 80 durometer feels substantial without being too stiff.7 pack covers a couple of maintenance cycles for me.

Carter ★★★★★

The temperature range on these is what sold me, and I’ve had zero issues with them in a hot oil application. The 80 durometer feels substantial, and the 4.225" ID seated snugly without any wrestling. Solid buy.

Sophia ★★★★★

Finally, an o-ring that doesn’t crack after a season of heat cycling. The 80 durometer feels firm yet pliable, and the 4.225" ID fit my housing perfectly without any stretching struggle.
