Product Questions & Answers (3)

Question by: Diane W on Jul 24, 2025, 8:15 AM
fitting's got a 3/8 NPT female end on it -- does that mean it'll thread straight onto a standard pipe port without needing any kind of bushing or reducer in between?
Answer by: Customer Support on Jul 25, 2025, 7:33 PM
A 3/8-18 NPT female threads directly onto a standard 3/8 NPT male pipe port, no bushing or reducer needed. The male JIC end on the other side is a 7/16-20 with a 37-degree flare seat, so whatever line or fitting you're connecting there needs to match that spec. At 1.43 inches long it's a compact straight adapter, which makes it easy to work into tighter hydraulic connections runs without a lot of extra bulk.
Question by: Vince J on Jul 23, 2025, 3:04 PM
got a hose end that’s 7/16-20 JIC, will this adapter screw right onto it and still let me go into 3/8-18 NPT?
Answer by: Customer Support on Jul 25, 2025, 12:19 PM
For tying two common fitting styles together, this adapter gives you a 7/16-20 male JIC 37 degree flare on one side and a 3/8-18 female NPT on the other, in a straight steel body.
Question by: Jerry G on Sep 6, 2025, 6:02 AM
Will this adapter hold up okay in a hydraulic system that sees some pretty high pressures?
Answer by: Customer Support on Sep 7, 2025, 6:11 AM
This adapter is crafted from high-quality steel, which should provide a reliable and secure connection even under high-pressure conditions commonly found in industrial fluid transfer systems.
