Product Questions & Answers

What size is this exactly? I see the nominal size, but what's the actual width when you measure it?
Question by: Tommy W on Nov 3, 2025, 1:28 PM
The actual width of this O-ring is 0.21 inches.
Answer by: Customer Support on Nov 5, 2025, 6:05 AM
These come in a pack of 50, that right? Got a few machines to maintain and tryin to figure out if one order covers me or if I need multiples.
Question by: Randy S on Nov 15, 2025, 8:17 AM
50 pieces per package. For routine maintenance across several machines, that quantity tends to go fast, so ordering ahead is smart. Each ring measures 1.037 inches inner diameter and 1.457 inches outer diameter with a 0.21 inch width, so just make sure those dimensions line up with what your equipment calls for before you commit to a bulk order.

got a groove cut for a -319 o-ring. is this the right one or am i off a size?
Question by: Brenda G on Jun 12, 2025, 8:01 AM
Match it up by dash size and dimensions. This one is a Dash Size -319 Buna-N O-ring with an actual ID of 1.037 inches, actual OD of 1.457 inches, and a 0.21 inch cross-section width, which lines up with the nominal 1-1/16 inch ID and 1-7/16 inch OD.
