Madison D. ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure hydraulic fitting—no squish or deformation after a full day of cycling. Price per pack is solid for genuine Viton FKM that handles up to 400°F without any signs of cracking.

Jason ★★★★★

I was replacing old gaskets on a steam line and these Viton FKM rings slipped right into the groove without any tweaking. The 90 durometer feels firm and durable, and they've held up perfectly through several high-heat cycles.

Ryan ★★★★★

The 90 durometer on these Viton rings feels reassuringly firm for a high-temp seal application. I installed a few on a steam valve and they seated perfectly without any distortion. For the price of a 60-pack, this is a solid deal.
