got a -219 groove already cut. are these the right quad rings for that size?

Answer by: Customer Support on Feb 3, 2026, 1:01 PM

Match-up comes down to the dash size. These are dash size -219 Style QR Buna-N quattro rings, so they are the -219 quad ring size.

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

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

Answer by: Customer Support on Sep 30, 2025, 3:38 PM

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.

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