Part Number: 2405

37° Male JIC x Female NPTF Pipe Connector

Product Overview

The Delphi Fittings Part 2405 is a straight connector (adapter) designed to create a reliable bridge between JIC (Joint Industry Council) 37° flare systems and NPTF (National Pipe Taper Fuel / Dryseal) threaded components. This versatile fitting features a male JIC 37° flare on one end and a female NPTF pipe thread on the other. It is typically used to connect a female JIC swivel fitting (e.g., on a hydraulic hose) or a flared tube to a male NPTF threaded pipe or fitting. Manufactured from high-quality carbon steel and zinc-plated for enhanced corrosion resistance, the Part 2405 connector ensures a secure, leak-resistant transition in various hydraulic and industrial applications.

Applications

The Part 2405 connector is widely used for interfacing JIC flare systems with male NPTF components:

Connecting JIC hydraulic hoses or flared tubes to male NPTF-ended components such as nipples, certain sensors, or other adapters.
Integrating equipment using JIC standards with piping systems that terminate in male 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, female NPTF threads, and mating male NPTF threads) are clean, undamaged, and free of contaminants.
Connect the male JIC end of the adapter 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.
For the female NPTF end, thread it onto the mating male NPTF pipe or fitting. 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 it's a standard NPT male or for high pressures, to ensure a leak-proof connection. Tighten with a wrench to the recommended specification.
Use backup wrenches on the adapter body and mating components as needed to prevent distortion or damage during tightening.
