Question by: Daryl B on Nov 24, 2025, 4:20 PM
got a groove that calls for a -016 quad ring, is this the right size or am i mixin stuff up
Answer by: Customer Support on Nov 26, 2025, 8:03 AM
The key callout here is the dash size. These are Style QR Quattro Rings in -016 size, so they match applications that specify a -016 quad ring.
Question by: Eddie T on Mar 2, 2026, 7:25 AM
these quad rings rated for heat? got an application runnin pretty hot and need somethin that'll hold up
Answer by: Customer Support on Mar 3, 2026, 7:37 AM
Buna-N handles a range from -40°F up to 240°F, so moderate heat is no problem for these. If your application stays under that 240°F ceiling, you're in good shape. Anything pushing above that threshold would need a different material.
Question by: Hubert L on Jan 26, 2026, 7:10 PM
What kinda temps can these rings handle before they give out? Just wanna make sure they'll hold up in my setup.
Answer by: Customer Support on Jan 28, 2026, 8:03 AM
These Buna-N quad rings are good for use in systems operating between -40°F and 240°F.
