Henry B. ★★★★★

These fit the 044 spec exactly and the 75 durometer feels sturdy enough for repeated sealing. I’ve got them in a steam application approaching 350°F and they haven’t hardened or cracked after two weeks of cycling.

Ellie O. ★★★★★

Installed these on a hot oil line that sees constant 300°F cycling and they haven't shown any sign of hardening after a month. The 0.07" cross-section is a perfect snug fit for the groove depth I needed.

Carter ★★★★★

The -15°F to +400°F range covers everything from my freezer door seals to the hot oil lines, so I grabbed a pack for both. These Viton rings are stiff enough at 75 durometer to seat firmly without deforming during install. Exact fit on the 3.739" bore, zero leaks after a week of cycling heat.
