Question by: Cheryl Y on Mar 31, 2026, 1:49 PM

got a hose end with 3/8-24 JIC on it. is this union the right deal to join two male JIC ends together?

Answer by: Customer Support on Apr 1, 2026, 5:44 PM

Function-wise, it is a straight MJIC union with male JIC SAE 37 degree flare threads on both ends, and both ends are 3/8-24 per SAE J514. That means it is made to connect into two matching female JIC 37 degree flare fittings, not to directly couple two male JIC ends together.
