Product Questions & Answers

Just want to make sure, this is a 90 degree elbow, right? Need somethin' that makes a turn.

Question by: Dwight H on Jun 21, 2025, 9:26 AM

Correct, this steel adapter forms a precise 90-degree elbow, transitioning from a 9/16-18 male SAE O-Ring Boss to a 1/4-18 male NPT connection. It's designed for applications where you need to change direction.

does this adapter need any thread sealant on either end, or is it good to go as-is?

Question by: Bobby M on Dec 19, 2025, 5:13 PM

The SAE O-Ring Boss end seals through the o-ring itself, so no thread sealant is needed there. The male NPT side also connects without requiring additional sealants, according to the product specs. Both ends are set up to give you a secure, leak-proof fit right out of the box.
