Eli V. ★★★★★

I needed o-rings that could handle high heat for a lab setup, and these fluoroelastomer ones are holding up perfectly at 350°F. The 60 durometer feels just right, not too stiff or soft.

Andrew ★★★★★

These o-rings fit perfectly in my steam valve application, and the 60 durometer is firm enough to hold a good seal without being difficult to install. The 400°F temperature rating gives me confidence they'll last.

Thomas R. ★★★★★

The white color makes them easy to spot during inspection, and the 60 durometer hardness feels just right for a snug fit on the 3.859" bore without struggling to install. Handled a 300°F test run with zero deformation, so I'm confident in the -15°F to +400°F rating holding up long-term.
