Ruby ★★★★★

The cross-section on these 334 o-rings is noticeably thicker than standard ones I've used, making them feel much more robust. They seated perfectly in my pump housing and should handle the high-temp fluid I'm circulating. Really solid buy for the price.

Mia G. ★★★★★

Installed a set of these on a hot oil line that runs around 300°F, and the X-ring profile really helped them stay seated where standard o-rings used to squirm out. The 70 durometer feels just right, firm enough for the pressure but not brittle. Six months in, not a single leak.

Ryan H. ★★★★★

These held up great when I needed to seal a high-temp oil line; the Viton FKM material handled the 350°F heat without any softening. The 2.6" inner diameter was a perfect fit for my application, and the 70 durometer gave just the right amount of compression.
