Parker 159F-6-6 Brass 45 Degree Flare Male Elbow 3/8 Inch

Product Description

The PARKER 159F-6-6 is a brass 45-degree flared tube male elbow fitting designed for use in fluid and gas line assemblies requiring a direction change at a 45-degree angle. It features a flare end on one side and a male NPTF threaded end on the other, allowing a flared tube to connect to a standard tapered pipe thread port. With a maximum working pressure of 1000 psi and a maximum working temperature of 250 degrees F, this fitting is suited for demanding hydraulic, refrigeration, and fuel line applications. Licensed plumbers, HVAC technicians, and fluid power mechanics are the typical installers of this type of fitting.

This fitting is used in residential and commercial systems where 3/8-inch OD flared tubing must transition to a male NPTF threaded connection at a 45-degree angle. Common applications include refrigeration lines, fuel systems, hydraulic circuits, and compressed air assemblies. The 3/8-18 thread size is a standard NPTF designation, making this elbow compatible with a wide range of valves, manifolds, and equipment ports that accept that thread pattern. It meets SAE J512, SAE J513, and UL Listing standards.

Key Features

• 45-degree flared tube male elbow configuration for direction changes in tight spaces
• Flare x MNPTF end connections for transitioning flared tubing to tapered pipe threads
• Brass construction offers good corrosion resistance and machinability
• Rated to 1000 psi maximum working pressure
• Rated to 250 degrees F maximum working temperature
• Meets SAE J512, SAE J513, and UL Listing standards

Compatibility

Designed for use with 3/8-inch OD flared tubing and equipment ports with a 3/8-18 NPTF male thread. Suitable for refrigeration, fuel, hydraulic, and compressed air systems requiring SAE-standard flare fittings.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or fluid power mechanic familiar with flared tube fittings and tapered pipe threads. Depressurize and isolate the system completely before removing or installing any fittings. Flare connections require a properly formed 45-degree flare seat on the tubing; inspect the flare for cracks or deformation before assembly. NPTF threads are designed for dry-seal connections, but consult applicable codes such as the IPC or IFGC regarding the use of thread sealants in your specific application.
