James ★★★★★

Replaced the old cracked seals on a pneumatic cylinder and these seated perfectly first try. The 70 durometer is firm enough for a reliable seal but they still compressed easily into the groove. Having a full box of 500 means I've got spares for any future project.

Abigail O. ★★★★★

These fit perfectly on my pneumatic fittings, and the 70 durometer feels just right for a reliable seal. Shipping was fast and I got exactly 500 as advertised.

Riley U. ★★★★★

I needed a bulk pack of these for a hydraulic repair job, and the 70 durometer hardness turned out to be just what the application required. They seated perfectly in the groove without any binding.
