Answer by: Customer Support on May 19, 2025, 8:29 AM
For a 0.75 inch tube size SAE O-Ring Boss (straight thread) connection, this matches that size callout and is a Buna-N o-ring with a 0.924 inch ID and 1.156 inch OD.
Question by: Brent O on Sep 3, 2025, 9:41 AM
got a 3/4 inch SAE O-ring boss fitting that keeps weepin' at the connection, this the right size ring to fix that?
Answer by: Customer Support on Sep 4, 2025, 8:38 PM
For a 3/4 inch tube size SAE O-Ring Boss straight thread fitting, yes, this is the correct replacement. The inside diameter is 0.924 inches and the outside diameter is 1.156 inches, which is what that port size calls for. The Buna-N material at 90 durometer gives you a firm, reliable seal that holds up well under the compression a straight thread boss fitting applies to the ring.
