Michael T. ★★★★★

I needed a bulk pack for a custom pneumatic project, and the 70 durometer square profile seals nicely in the groove without binding. These handled a quick heat cycle test up to 200°F without any noticeable swelling or hardening.

Hannah ★★★★★

Fits perfectly in my hydraulic cylinder repair kit, and the 70 durometer feels just right for the application. The package of 250 will last me for years at this rate.

Emily V. ★★★★★

The square profile on these 219 o-rings cinched down perfectly in the groove without rolling, and the 70 durometer felt just right for my hydraulic fitting. Used a full pack on a batch of air cylinders and had zero leaks during the pressure test.
