Anderson Metals 754042-06 Brass Flared Tube Union 3/8 in

Product Description

The ANDERSON METALS 754042-06 is a lead-free brass flared tube union designed to join two flared tubing runs in a single inline connection. It uses a 45-degree flare angle with flare x flare end connections on both sides, creating a secure, leak-resistant joint without soldering. Rated for up to 1000 psi working pressure in both static and dynamic service, this union is built for demanding plumbing, refrigeration, and HVAC line applications where a removable mechanical connection is required. Licensed plumbers and HVAC-R technicians are the primary installers.

This fitting is suited for residential and light commercial installations involving copper tubing with a 3/8 inch outside diameter. Common applications include refrigerant lines, fuel gas distribution, and potable water systems where lead-free material compliance is required. The flare x flare configuration allows the union to be disconnected and reconnected without cutting the tubing, making it practical for service access points in refrigerant circuits and pressurized fluid lines.

Key Features

• Lead-free brass construction meets low-lead requirements for potable water applications
• 45-degree flare angle on both ends for standard SAE flare compatibility
• 1000 psi maximum working pressure, static and dynamic
• Flare x flare end connection allows disassembly without cutting tubing
• 3/8 inch tube OD sizing fits standard copper refrigerant and water lines

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 3/8 inch OD copper tubing with standard 45-degree SAE flare connections.

Installation Notes

Installation should be performed by a licensed plumber or HVAC-R technician. Shut off and depressurize the line completely before disassembling or installing any flare fitting. Use a calibrated flaring tool to ensure a proper 45-degree flare seat on the tubing ends before threading the union nuts; an improperly formed flare is the leading cause of leaks at this joint type. Verify compliance with applicable local plumbing codes and ASHRAE standards before placing the system back into service.
