Parker 150F-10-12 Brass Female Elbow 5/8 in Flare X Fnptf

Product Description

The PARKER 150F-10-12 is a brass flared tube female elbow designed for use in hydraulic, pneumatic, refrigeration, and fluid transfer systems where a 45-degree flared tube connection must transition to a female National Pipe Thread Fuel (NPTF) port. Constructed from brass, this fitting accepts a 5/8 inch tube OD on the flare end and threads into a 3/4-14 NPTF female port. The 45-degree flare angle provides a reliable metal-to-metal seal at the tube connection. Licensed plumbers, HVAC technicians, and refrigeration mechanics install this type of fitting during equipment hookup and line set connections.

This fitting is suited for residential and light commercial applications where copper or brass tubing must connect to a fixed female threaded port at a 90-degree change in direction. Common install scenarios include refrigerant line connections, fuel delivery systems, hydraulic circuits, and compressed air or gas lines where both a leak-free flare seal and a threaded port engagement are required. The elbow configuration reduces stress on tubing runs by eliminating sharp bends near the connection point.

Key Features

• 45-degree flare angle provides a metal-to-metal seal without additional sealant on the tube side
• 5/8 inch tube OD flare end accommodates standard copper and brass tubing
• 3/4-14 NPTF thread engages female NPT ports with fuel-rated thread form for positive sealing
• Brass construction offers corrosion resistance and compatibility with a wide range of fluids and gases
• Flare x FNPTF end configuration allows tube-to-pipe transitions in a single fitting

Compatibility

Designed as an OEM-style and aftermarket replacement flare fitting for systems using 5/8 inch OD tubing with a 45-degree flare termination connecting to 3/4-14 NPTF threaded ports.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or refrigeration mechanic familiar with flared tube fittings and NPTF thread engagement. Shut off and depressurize the system completely before disassembling existing fittings or making new connections. The NPTF thread side typically requires thread sealant or PTFE tape rated for the service fluid; verify compatibility before applying any sealant. Inspect the tube flare for concentricity and surface condition before torquing the nut, as a damaged flare face will not seal reliably.
