Product Questions & Answers (4)

Question by: Neil H on Dec 20, 2025, 6:09 AM
got a hose end with a 3/4-16 JIC swivel on it. is this the right adapter to go over to 3/8-18 pipe thread?
Answer by: Customer Support on Dec 21, 2025, 3:59 PM
Use-case wise, yes, it’s a straight steel adapter that mates a 3/4-16 female JIC 37 degree flare swivel end to a 3/8-18 male NPTF pipe thread.
Question by: Larry P on Nov 4, 2025, 11:01 AM
Will this adapter work for connecting a 3/8" male NPT to a 3/4" female JIC?
Answer by: Customer Support on Nov 6, 2025, 6:13 AM
Yes, this Eaton Aeroquip adapter is specifically made for connecting a 3/8-18 male NPT to a 3/4-16 female JIC 37-degree flare swivel.
Question by: Wade M on Jul 16, 2025, 10:10 AM
Got a 3/8 NPT port on a pump housing and need to hook up a -8 JIC hose end. This the right adapter for that?
Answer by: Customer Support on Jul 18, 2025, 6:12 AM
That's what this one's for. The male end threads into a 3/8-18 NPT port, and the female swivel end accepts a 3/4-16 JIC fitting, which is the standard thread for a -8 JIC hose end. The 37-degree flare on the female side matches up with standard SAE JIC hose assemblies, so you'll get a proper metal-to-metal seal at that connection. Steel construction, straight configuration, no angled body to work around.
Question by: Cindy A on Aug 3, 2025, 7:16 AM
trying to hook a 3/8-18 pipe thread port up to a 3/4-16 JIC line, is this the right adapter?
Answer by: Customer Support on Aug 4, 2025, 1:43 PM
For that thread combo, yes. It is a straight steel adapter with a 3/8-18 male NPT pipe thread on one end and a 3/4-16 female JIC 37 degree flare swivel on the other.
