got a tight spot on my line, is this the 45 elbow that goes from a -4 JIC male flare over to 1/8 male NPT?

For routing around a corner, this adapter gives you a 45 degree elbow with a -04 male JIC 37 degree flare on one end and a 1/8 inch male NPT on the other, so it’s meant for exactly that JIC to NPT transition.

Got a tight spot near a sensor port on my hydraulic manifold where I need to adapt a -4 JIC line down to a 1/8 NPT fitting. This 45-degree elbow going to work for that kind of situation?

For tight quarters like that, the 45-degree angle on this fitting gives you some real flexibility in how the hose routes away from the port. The male JIC 37-degree flare on one end connects to your -04 JIC line, and the 1/8 inch male NPT threads into your manifold port directly. That combination is pretty common on sensor taps and pilot ports where space is limited and a straight adapter just won't clear surrounding hardware.

What size is this fitting, and what kind of threads does it have?
Answer by: Customer Support on Mar 27, 2026, 7:50 PM
It's a -04 JIC 37-degree flare on one side and a 1/8-inch male NPT on the other. That JIC is a common hydraulic thread.
