Sofia ★★★★★

I needed an o-ring that could survive 400°F near my engine, and this Viton FKM version handles it without breaking a sweat. The 5.234-inch inner diameter fit perfectly on my application, and the 70-durometer material feels solid.

Charlotte H. ★★★★★

Finally found o-rings that can handle the 400°F limit my compressor needs; the 70 durometer feels solid and not brittle. These Viton ones are exactly the right size for the seal and should last much longer than standard rubber.

Leo ★★★★★

These fit perfectly on my high-temp air line fitting where standard Buna-N rings kept failing. The Viton FKM material handles the 200°F operating temperature without any issue.
