these quad rings rated for high heat or just regular shop temps? got some equipment that runs pretty warm

Question by: Clint G on Sep 29, 2025, 8:06 AM

Buna-N handles a range of -40°F up to 240°F, so moderate heat is no problem. If your equipment stays under that upper limit, these should hold up fine in the application.

What's the temp range on these rings? Gotta make sure they can handle the heat.

Question by: Dale M on Mar 12, 2026, 6:14 AM
