Question by: Larry G on Mar 18, 2026, 1:30 PM
i got a groove set up for a -023 o-ring. is this the right one, and what are the real measurements?
Answer by: Customer Support on Mar 20, 2026, 7:59 AM
Match it up by dash size first, since this one is a -023. The actual dimensions are 1.051 inch ID, 1.191 inch OD, with a 0.07 inch cross section, which is meant to fit standard groove configurations for that size.

These come in a pack of 50, is that the only option, or can you buy just a few at a time?
Answer by: Customer Support on Sep 15, 2025, 8:15 AM
The package quantity on this one is 50 units, and that's the standard way they're sold. For shops running equipment that goes through o-rings regular, a pack of 50 usually makes more sense anyway since you'll want spares on hand when one gives out mid-job.

What’s the temp range on these o-rings? Gotta make sure they can handle the heat.
Answer by: Customer Support on Jul 18, 2025, 6:23 AM
These Buna-N o-rings are rated for a temperature range of -40°F to 240°F, making them suitable for a variety of operating conditions.
