Chloe ★★★★★

The -15°F to +400°F range is exactly what I needed for a hot oil line in my shop, and the 75 durometer feels stiff enough to hold its shape under pressure. These Viton rings seated perfectly in the groove without any stretching or tearing, so I’ve got no leaks after a week of heavy use.

John ★★★★★

Installed these in an old hydraulic valve that kept leaking at 300°F, and the Viton FKM material finally sealed it tight. The 0.21" cross-section fit perfectly into the groove, and after a week of use, no signs of hardening or cracking.

Zoe ★★★★★

I've been using these for a high-temp pneumatic valve rebuild and the 75 durometer holds up better than the old Buna-Ns I had before. So far no leaks even with the valve cycling in a 300°F environment.
