Product Questions & Answers (2)

Question by: Howard E on Feb 18, 2026, 3:07 PM
got a straight thread SAE o-ring boss fitting, is this the right o-ring size for the 1/4 tube stuff?
Answer by: Customer Support on Feb 19, 2026, 6:38 PM
For a 0.25 inch tube size SAE O-Ring Boss (straight thread) connection, this matches the listed tube size and it is a Buna-N o-ring. The ring dimensions are 0.351 inch ID, 0.495 inch OD, and 0.072 inch width.
Question by: Neil B on Apr 14, 2025, 11:28 AM
fits a 1/4 inch SAE o-ring boss port? just want to make sure before i order a handful of these
Answer by: Customer Support on Apr 16, 2025, 10:53 AM
That's what this one's built for. The inner diameter runs 0.351 inches with an outer diameter of 0.495 inches and a width of 0.072 inches, which puts it right in spec for 1/4 inch SAE O-Ring Boss straight thread fittings and adapters. The Buna-N material at 90 durometer gives it a firm enough seat to hold tight without deforming under normal torque.
