Henry B. ★★★★★

The 400°F temperature rating is exactly what I needed for a hot steam line that kept cooking cheaper rubber rings. These Viton ones held their shape perfectly after a week of constant exposure, and the 30-pack means I've got spares for the next rebuild.

Evelyn ★★★★★

Installed these in a hydraulic manifold running around 350°F and the 70 durometer Viton sealed perfectly with no creep. The 2.111" ID is spot-on for the groove, and the 30-pack gives plenty of spares for future maintenance.

David ★★★★★

I needed a reliable seal for a high-temp application, and the 70 durometer of these Viton rings handles the 400°F range just fine. They stretched on without any cracking, and the 2.111" ID matched my groove perfectly. Really solid pack for the price.
