Question by: Warren G on Jul 26, 2025, 12:22 PM
got a line stepping down from 3/8 to 1/4 JIC and need something to tie them together without a bunch of extra fittings in the way, this what I'd be looking at?
Answer by: Customer Support on Jul 28, 2025, 8:19 AM
For a straight reducing union between 9/16-18 and 7/16-20 male JIC 37 degree flare ends, yes, that's exactly what this fitting does. Both sides are male JIC with the standard 37 degree flare seat, so it bridges those two thread sizes in one compact piece. Overall length is 1.4 inches, so it keeps things tight without adding much run to your line.
