Sophia S. ★★★★★

Took a chance on these for a hydraulic rebuild and the 70 durometer hardness feels exactly right for the job. The 1.609" ID seated perfectly in the groove without any wrestling. Nice to have a full 400 pack on hand so I'm not scrambling next time.

Mia F. ★★★★★

I was worried about getting the right seal for my hydraulic application, but these o-rings fit perfectly on the 1.609" ID and the 70 durometer material held up well under 200°F oil exposure. The quantity of 400 in the pack should last me through several rebuilds.

Amelia C. ★★★★★

The 70 durometer feels just right for my pneumatic fittings, and the -40°F rating gives me confidence for outdoor use. I've used a few different o-rings before, but the Buna-N material in these seals without any leaks.
