Part Number: 2404

37° Male JIC x NPTF Male Pipe Connector

Product Overview

The Delphi Fittings Part 2404 is a straight connector designed to bridge JIC (Joint Industry Council) 37° flare systems with NPTF (National Pipe Taper Fuel / Dryseal) threaded ports. This versatile adapter features a male JIC 37° flare on one end and a male NPTF pipe thread on the other. It is commonly used to connect a hydraulic hose with a female JIC swivel nut or a flared tube directly to a component with a female NPTF port, such as those found on valves, pumps, or manifolds. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2404 connector ensures a secure, leak-resistant transition between these two widely used hydraulic connection standards.

2404-16-16: 1" (1-5/16-12) JIC Male x 1" NPTF Male

Note: Long (2404L) and Extra Long (2404LL) versions are also available for applications requiring extended NPTF thread reach. For unlisted size combinations, please contact our sales team.

Applications

The Part 2404 connector is essential for interfacing JIC and NPTF systems:

Connecting JIC hydraulic hoses or flared tubes to NPTF ports on hydraulic components like pumps, valves, cylinders, and manifolds.
Integrating equipment using JIC standards into systems predominantly featuring NPTF threads.
Common in mobile equipment, agricultural machinery, industrial hydraulics, and general fluid power applications requiring a transition between these fitting types.

Installation & Usage Guidelines

Ensure all threads and sealing surfaces (JIC male flare, mating JIC female seat, male NPTF threads, and mating female NPTF port threads) are clean, undamaged, and free of contaminants.
For the NPTF end, thread the male NPTF into the female NPTF port. While NPTF provides a dry seal, it is often recommended to use a compatible thread sealant (PTFE tape or paste) on the male NPTF threads, especially if mating with a standard NPT port, to ensure a leak-proof connection. Tighten with a wrench to the recommended specification.
Connect the male JIC end to the female JIC swivel nut. Ensure the 37° flare surfaces align correctly. Tighten the JIC nut to the recommended torque. No sealant is used on JIC flare connections.
Use backup wrenches on the adapter body and mating components as needed to prevent distortion or damage during tightening.
