Question by: Phil W on Oct 12, 2025, 8:38 AM
What size wrench do I need for this fitting? Just want to make sure I got the right tools ready.
Answer by: Customer Support on Oct 14, 2025, 6:13 AM
This adapter features 9/16-18 threads on both ends, so that's the size you'll be working with.
Question by: Rod C on May 28, 2025, 9:32 PM
i just need a straight union, are both ends on this thing 9/16-18 male ORB?
Answer by: Customer Support on May 30, 2025, 6:08 PM
For a straight-through union between two same-size ORB ports, this adapter matches 9/16-18 male SAE O-ring boss threads on both ends, so it is a 9/16-18 MORB to 9/16-18 MORB straight union.
Question by: Steve F on May 11, 2025, 6:24 AM
both ends are the same thread size right? just want to make sure before I order, running 9/16-18 on both sides of my setup
Answer by: Customer Support on May 12, 2025, 12:55 PM
Correct on both ends. The adapter carries 9/16-18 male SAE O-ring boss threads on each side, so it functions as a union, connecting two matching ports without any thread conversion. If your system already runs that thread size on both ends, this fitting drops right in.
