Customer Reviews (4.8 / 5 · 5 reviews)

Penelope W. ★★★★★

I needed a size 047 for a quick pump rebuild, and these came in a bulk pack for a fair price. The 70 durometer rubber feels just right for sealing against oil without being too stiff. Good stock to have on hand for future repairs.

Mia E. ★★★★★

These o-rings fit my hydraulic cylinder perfectly, and the 70 durometer gives them just the right amount of firmness without being brittle. I've had them on for a few weeks now with no signs of leaking or wear.

Benjamin S. ★★★★★

I needed a high-temp seal for a steam fitting, and these Buna-N rings handled 250°F without any softening. The cross-section is exactly 0.07", so they seated snugly in the groove.
