Question by: Warren E on Mar 25, 2026, 4:01 PM
trying to hook a JIC line to a JIS port, is this the right adapter for that?
Answer by: Customer Support on Mar 27, 2026, 6:21 AM
For connecting those two standards, it bridges a 9/16-18 UNF JIC male end to a G 3/8-19 JIS male end. Both sides are 3/8 size, and it is a straight steel adapter meant to make a secure, leak-free connection between compatible hydraulic lines.

Will this fitting hold up okay in a hydraulic system that runs pretty much non-stop all day?
Answer by: Customer Support on Nov 5, 2025, 8:45 AM
Manufactured by Adaptall with robust steel, this adapter is durable enough to meet the requirements of demanding industrial environments.
Question by: Johnny R on Nov 1, 2025, 1:33 PM
What thread types does this adapter connect on each end, and are both sides the same size?
Answer by: Customer Support on Nov 3, 2025, 8:14 AM
Both ends are sized at 3/8", but the thread types are different. One side is a 9/16-18 UNF JIC male, and the other is a G 3/8-19 JIS male. So you're getting a straight adapter that bridges those two standards without any size change between ends.
