Kevin F. ★★★★★

I've been using these for hydraulic seals on a press running at 350°F, and they've held up perfectly with no swelling or cracking. The 75 durometer is just right for the pressure we're dealing with.

Eva ★★★★★

The durometer feels spot-on for a 75—firm enough to seat properly but not so stiff that they crack during installation. I’ve used these in a hot oil line hovering around 300°F and they’ve held their shape perfectly over two months.

Hazel W. ★★★★★

These handled the 400°F service range without any softening or deformation when I used them to seal a hot oil line. The -15°F low-end rating gives me confidence for winter storage too. Having 18 in the pack meant I had spares for the inevitable fumble on the garage floor.
