Parker 145F-6-8 Brass Male Branch Tee 3/8 in Flare

Product Description

The PARKER 145F-6-8 is a brass male branch tee fitting designed for flared tube connections in refrigeration, HVAC, and fluid-handling systems. It features a 45-degree flare seat on the tube end and a 1/2-14 NPTF male thread on the branch port, with an outside diameter of 3/8 inches. This fitting joins a straight tube run to a threaded branch outlet in a single compact body. Licensed HVAC technicians and plumbers install this type of fitting where a branch takeoff is needed without cutting into an existing line with a separate tee and adapter. The all-brass construction resists corrosion in refrigerant, fuel gas, and hydraulic service lines.

This fitting is suited for residential and light commercial HVAC systems, refrigeration piping, and pneumatic or hydraulic fluid lines where tube OD sizes of 3/8 inches and 1/2-14 threaded ports are called for. It is commonly installed during new construction and service work where a reliable branch connection must be made between a flared copper or aluminum tube and a male NPT-threaded component such as a valve, gauge port, or manifold. The 45-degree flare geometry is standard for SAE-spec refrigerant and fuel-gas tubing assemblies.

Key Features

• 45-degree flare seat matches SAE standard flared tube fittings used in refrigerant and fuel-gas lines
• 1/2-14 NPTF thread provides a pressure-tight mechanical seal without additional sealant on the male branch port
• 3/8-inch tube OD sizing accommodates standard refrigerant and hydraulic copper tubing
• All-brass construction offers corrosion resistance across refrigerant, pneumatic, and hydraulic service environments
• Compact male branch tee body eliminates the need for a separate adapter at the branch outlet

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8-inch OD flared tube connections with 1/2-14 NPTF male branch ports, consistent with SAE 45-degree flare standards common in HVAC, refrigeration, and fluid-line assemblies.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with applicable mechanical codes and refrigerant handling regulations. Depressurize and evacuate any line containing refrigerant or pressurized fluid before disassembly. Ensure the tube end is properly flared to a true 45-degree seat using a calibrated flaring tool before torquing the fitting. Do not use pipe thread sealant on NPTF threads unless specifically required by the system manufacturer, as NPTF threads are designed for dry-seal engagement.
