Mia V. ★★★★★

The square profile on these 216 o-rings seated perfectly in my groove, and the 70 durometer feels just right for the pressure. I've used them in a couple of test assemblies so far with no leaks.

David O. ★★★★★

The square profile seats perfectly in the groove without rolling, and the Viton handles the 300°F heat cycling in my application without any softening. These are exactly the right dimensions for the AS568-216 spec, and forty pieces means I’ve got spares for the next rebuild.

Scarlett ★★★★★

Needed a square-profile seal for a high-temp valve rebuild and the 70 durometer on these is just firm enough to hold without being a brute to install. The -15°F to 400°F rating gives me peace of mind for the hot oil lines I'm using them on.
