Timothy V. ★★★★★

The inner diameter measurement was spot on for the hydraulic fitting I needed to seal, and the pack of 600 will last me years. These rings feel much more substantial than the cheap ones I've used before, especially at the 70-durometer spec. For a straightforward industrial seal, they're exactly what

George ★★★★★

I was worried about finding the right o-rings for a coolant line repair, but these measured exactly to the 0.921" ID and the 70 durometer felt just right when I seated them. They sealed up perfectly on the first try, no leaks at all.

Thomas L. ★★★★★

I was worried about getting the exact fit, but these 0.921" ID o-rings slid perfectly into the grooves on my hydraulic assembly. The 70 durometer feels sturdy without being too stiff, and the 600-pack means I've got plenty for future repairs.
