Product Questions & Answers

got a 9/16-18 SAE port on a machine, is this the right coupling thread for it?

Question by: Rusty H on Oct 12, 2025, 2:12 PM

The key callout on this coupling is the 9/16-18 SAE UN-2B internal thread. If your mating part is 9/16-18 SAE, that thread spec matches what this coupling is made with.

does this coupling work with standard SAE fittings or do i need something special to hook it up?

Question by: Rick M on Dec 9, 2025, 8:04 PM

The thread on this coupling is a 9/16-18 SAE UN-2B, so it mates with standard SAE fittings using that same thread spec. The socket weld end connects to your pipe or tubing through a weld joint rather than a threaded connection on that side, so as long as your fittings match the SAE thread and your fabricator can handle the weld side, you are good to go with standard hardware.
