Product Questions & Answers (2)

Question by: Judy C on Dec 29, 2025, 4:57 PM
Does the female end on this thing take a 9/16-18 thread, or am I reading the part number wrong?
Answer by: Customer Support on Dec 31, 2025, 3:55 PM
You're reading it right. The female JIC end is 9/16-18, built to SAE J514 spec with a 37-degree flare seat. The male end steps down to 1/2-20, same flare spec. So if you've got a 9/16-18 female port needing to connect to a 1/2-20 male fitting, this reducer handles that transition straight through with no bends or offsets.
Question by: Howard S on Sep 26, 2025, 6:31 AM
Will this here reducer work with standard JIC fittings? Just wanna make sure before I order.
Answer by: Customer Support on Sep 27, 2025, 12:16 PM
Yes, this straight reducer is designed to meet SAE J514 specifications, so it'll work with standard JIC SAE 37-degree flare fittings.
