Aurora ★★★★★

After clamping down a few of these in a test fitting, the 90 durometer is definitely firm enough for a high-pressure seal without deforming. The 0.237" ID was a perfect match for our brass fittings, and having 1200 in the bag means we won't be ordering again for a long time.

Lucy ★★★★★

I needed a bulk pack of #108 o-rings for a repair job, and the 90 durometer material feels substantial without being brittle. The 1200 count is way more than I'll use, but the price per ring makes it worth having extras.

Mia Y. ★★★★★

The 0.103" cross-section fits snugly in my hydraulic fittings, and the 90 durometer holds up well under pressure. I've been using these for a week with no leaks at all. Just wish the package came with a few extra, but 1200 is plenty for my needs.
