Brian ★★★★★

These Viton FKM o-rings handled my high-heat seal replacement perfectly, holding up at 350°F without any softening. The 60 durometer material feels flexible yet durable, and the white color is a nice change from standard black.

Eli ★★★★★

Finally found O-rings that don’t crack after a few months in hot oil. The 3.734" inner diameter fit my housing perfectly, and the white color makes them easy to spot during assembly.

Abigail ★★★★★

The 60 Durometer feels just right for my application—soft enough to seal without being too squishy. I specifically needed something that could handle occasional steam heat, and the 400°F max rating gives me confidence. These white rings fit the groove perfectly.
