Customer Reviews (4.6 / 5 · 5 reviews)

Hannah ★★★★★

These fit perfectly on the flange I needed to seal, and the 70 durometer gives just enough squish without feeling too stiff. Nice to have them in bulk since I always lose one or two.

Julian H. ★★★★★

The 70 durometer is the perfect firmness for my hydraulic cylinder seals — they seat without deforming. I'm already planning to reorder since the 110-pack handles multiple rebuilds easily.

Isabella Z. ★★★★★

I’ve been using these 0.07” cross-section o-rings for a few weeks now, and they fit perfectly in my hydraulic assembly. The 70 durometer feels just right—firm enough to seal without being too stiff. Really glad I picked up a pack of 110 for this price.
