Abigail D. ★★★★★

The 90 durometer hardness is exactly what I wanted for a high-temp seal, and these fit the groove perfectly on the first try. Handled 350°F steam without a hint of deformation across a full weekend.

Thomas U. ★★★★★

I needed o-rings that could take serious heat, and these—rated to 400°F—handled a steam fitting job without any softening. The 4.1-inch inner diameter was spot on for the flange I was repairing.

Steven ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure seal, and they slid into the groove without tearing. Handled the 350°F heat cycle in my setup with zero leaks so far.
