Question by: Cody S on Sep 5, 2025, 9:20 PM

trying to swap out a straight fitting, what thread size is this one and how big is the hex?

Answer by: Customer Support on Sep 7, 2025, 7:51 AM

For fit-up, it uses a 13/16-16 thread and takes a 0.875 in. hex.

Question by: Floyd R on May 25, 2025, 8:27 AM

what thread size does this fitting run on, the 13/16-16?

Answer by: Customer Support on May 27, 2025, 6:35 AM

13/16-16 is correct. It's a standard thread size that works with SAE ports, so if you're running a typical mobile or industrial hydraulic setup, it should line right up with what you've already got in place.

Question by: Warren R on Jun 1, 2025, 8:26 AM

What size wrench do I need for this fitting?

Answer by: Customer Support on Jun 2, 2025, 12:23 PM

An 0.875 inch hex wrench will fit this straight fitting.
