Product Questions & Answers (2)

Question by: Lynn E on Feb 8, 2026, 9:12 PM
trying to swap out an old elbow, how do i know this one matches my threads?
Answer by: Customer Support on Feb 10, 2026, 12:35 PM
Start by checking what each end is. This adapter is a 90 degree steel elbow with an 11/16-16 male SAE O-Ring Face Seal on one side and a 3/4-16 male SAE O-Ring Boss straight thread with an O-ring on the other. If your two ports match those thread sizes and connection styles, it is the right fit.
Question by: Bonnie H on Jun 11, 2025, 10:22 AM
Hey, will this here elbow fitting work to join up a SAE O-ring face seal with a SAE O-ring boss? Just wanna make sure before I order it.
Answer by: Customer Support on Jun 12, 2025, 5:55 PM
Yes sir, it's designed to do just that, going from an 11/16-16 Male SAE O-Ring Face Seal to a 3/4-16 Male SAE O-Ring Boss connection.
