Part Number: 2501

37° JIC Male to NPTF Male Pipe 90° Elbow

Product Overview

The Delphi Fittings Part 2501 is a 90° adapter elbow designed to provide a secure, right-angle connection between a JIC (Joint Industry Council) 37° flare system and an NPTF (National Pipe Taper Fuel / Dryseal) threaded port. This fitting 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 to a component with a female NPTF port, such as those found on valves, pumps, or manifolds, where a 90-degree change in direction is required. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2501 elbow ensures a reliable, leak-resistant transition between these two widely used hydraulic connection standards.

Note: Long (2501L), Extra Long (2501LL), and Extra Extra Long (2501LLL) versions are also available for applications requiring extended NPTF thread reach. For unlisted size combinations, please contact our sales team.

Applications

The Part 2501 adapter elbow is essential for interfacing JIC and NPTF systems at a right angle:

Connecting JIC hydraulic hoses or flared tubes to NPTF ports on hydraulic components where a 90-degree turn is necessary for routing.
Integrating equipment using JIC standards into systems predominantly featuring NPTF threads with a directional change.
Common in mobile equipment, agricultural machinery, industrial hydraulics, and general fluid power applications.
Facilitating plumbing in tight spaces where a straight adapter is not feasible.

Installation & Usage Guidelines

Ensure all threads and sealing surfaces are clean, undamaged, and free of contaminants.
For the NPTF end, thread the male NPTF into the female NPTF port. Apply a compatible thread sealant (PTFE tape or paste) to 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, achieving the desired orientation.
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 elbow body and mating components as needed to prevent distortion or damage.
