Claire ★★★★★

I needed o-rings that could handle a steam application around 300°F, and the 400°F rating on these gave me peace of mind. The 75 durometer feels just right—firm enough to seal securely without being a nightmare to install.

Hannah P. ★★★★★

The high temp rating on these was exactly what I needed for my hot oil line, and the 9.984" ID fit perfectly with no slop. They feel substantial and durable, and so far no leaks at all.

Ryan ★★★★★

Needed a replacement for a gasket that kept failing at high temps, and these are the exact size I measured. The 75 durometer hardness feels just right, not too stiff when I wrestle them into place around that 10-inch bore.
