Sebastian ★★★★★

Needed a bulk set of 120-size o-rings for a pneumatic manifold rebuild, and the 70-durometer Buna-N seals compressed nicely into the glands. The consistent inner diameter kept everything aligned without binding.

William ★★★★★

Just finished rebuilding a pneumatic cylinder with these o-rings, and every one seated perfectly without any twisting. The 70 durometer hardness gives them just the right amount of squeeze for a reliable seal at 150 psi. For about 40 cents per ring, this pack should cover my projects for a couple ye

John ★★★★★

These o-rings seal perfectly on my hydraulic fittings, and the 70 durometer is firm enough to hold pressure without being a hassle to install. Having 800 in a bag means I’m set for months without worrying about running out.
