Parker 159F-6-2 Brass 45 Male Flare Elbow 3/8 in Tube Od

Product Description

The PARKER 159F-6-2 is a brass 45-degree male flare elbow fitting designed for use in tube-to-pipe connections requiring a directional change. It features a flare inlet on one end and a male NPTF threaded outlet on the other, providing a leak-resistant mechanical seal without additional sealant on the pipe threads. Rated to 1000 psi maximum working pressure and up to 250 degrees F, this fitting is suited for fuel, hydraulic, and refrigeration-adjacent tubing systems where a reliable 45-degree offset is required. The 3/8-inch tube OD flare end pairs with a 1/8-27 NPTF thread. Licensed tradespeople in HVAC, plumbing, and related mechanical trades install this type of fitting in both residential and light commercial applications.

The 159F-6-2 is used where a 3/8-inch OD tube must connect to a 1/8-27 NPTF male port at a 45-degree angle. Typical applications include fuel gas lines, hydraulic circuits, pneumatic systems, and refrigerant-adjacent copper or aluminum tube runs. The 45-degree elbow geometry reduces stress on tubing by allowing a gradual directional change in tightly routed assemblies. It is appropriate for both new installations and field repairs in residential and light commercial mechanical systems.

Key Features

• Flare x MNPTF end connections for a secure tube-to-pipe seal
• Rated to 1000 psi maximum working pressure
• Rated to 250 degrees F maximum working temperature
• Brass construction for corrosion resistance in fuel and fluid service
• Meets SAE J512, SAE J513, and UL Listing standards

Compatibility

Designed for use with 3/8-inch OD flared tubing and 1/8-27 NPTF threaded ports. Suitable for systems requiring SAE J512 and SAE J513 compliant flare fittings.

Installation Notes

Installation should be performed by a qualified technician familiar with flare-type tube fittings. Shut off all system pressure and depressurize the line before disassembly or installation. The flare end requires a properly formed 45-degree flare on the tube — inspect the flare seat for cracks or irregularities before torquing. NPTF threads are designed to seal on the threads themselves; refer to applicable system codes such as IFGC or ASME B31 for thread engagement and pressure testing requirements.
