Customer Reviews (4.8 / 5 · 5 reviews)

Violet ★★★★★

The 1.486" inner diameter fits perfectly on my hydraulic fitting, and the -40°F rating gives me confidence for cold-weather use. These o-rings feel durable and consistent out of the pack.

Lucy I. ★★★★★

Just received these and the cross-section feels perfectly consistent across every ring in the pack. I’m using them for a hydraulic seal repair and the 50 durometer is exactly what my application called for.

Riley ★★★★★

The durometer is spot on for my application—soft enough to seat properly but firm enough to hold pressure. I’ve used these in a few hydraulic fittings and they’ve held up fine in the 100°F range, no swelling or cracking after a week.
