Parker 144F-6 Brass Flared Tube Union 3/8 in 45 Degree

Product Description

The PARKER 144F-6 is a brass flared tube union designed for fluid and refrigerant line connections in HVAC, refrigeration, and hydraulic systems. This three-end union features a 45-degree flare angle with flare x flare x flare end connections, a 5/8-18 UNF thread size, and a 3/8 inch tube outside diameter. It handles working pressures up to 1000 psi and temperatures up to 250 degrees F, making it a reliable choice for high-pressure line sets and service work. Licensed HVAC technicians and plumbers install this fitting during system assembly, repair, or line extension tasks where a leak-free flare joint is required.

This union is suited for residential and commercial HVAC, refrigeration, and fluid transfer applications where 3/8 inch OD tubing must be joined at a 45-degree flare. The three-port union configuration allows branching or in-line connections within a single compact fitting. It conforms to SAE J512, SAE J513, and carries a UL Listing, making it appropriate for use in systems where listed components are specified by code or equipment manufacturer requirements.

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 3/8 inch OD tubing with 45-degree SAE flare connections per SAE J512 and SAE J513 standards.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. De-energize the system and recover any refrigerant or relieve fluid pressure before disassembling existing line connections. Use a calibrated flaring tool to produce clean, uniform 45-degree flares on the tubing ends before torquing the union nuts. Refer to applicable SAE standards and local mechanical codes for torque procedures and inspection requirements.
