Anderson Metals 754048-0402 Brass Flare Connector 1/4 Od

Product Description

The ANDERSON METALS 754048-0402 is a lead-free brass flared tube connector designed to join 1/4 inch OD tubing to a 1/8 inch male NPT threaded port using a 45-degree flare connection. The fitting uses a flare x MNPT end configuration, making it a standard choice for connecting soft copper or compatible tubing to threaded fittings in gas, refrigeration, and fluid system applications. It is rated for up to 1000 psi working pressure in both static and dynamic service. Licensed plumbers, HVAC technicians, and gas line installers regularly use this type of connector when transitioning between flared tubing runs and NPT-threaded components in tight service spaces.

This connector is suited for residential and light commercial applications where 1/4 inch OD tubing meets an NPT-threaded port. Typical install scenarios include LP and natural gas supply lines, refrigerant line connections, and hydraulic or pneumatic control circuits. The lead-free brass construction meets potable water and fuel system material requirements. Its compact size makes it well-suited for panel-mounted valve connections, instrument taps, and appliance gas train assemblies where space is limited and reliable seal integrity is critical.

Key Features

• Lead-free brass construction meets material standards for gas, refrigerant, and potable fluid service
• 45-degree flare x MNPT end connection provides a reliable leak-resistant mechanical seal without solder
• 1000 psi maximum working pressure rating for both static and dynamic applications
• 1/4 inch tube OD flare end mates with standard 1/4 inch flare nuts and tubing
• 1/8 inch NPT male thread for direct connection to NPT-tapped ports and fittings
• Compact single-piece body simplifies routing in confined installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4 inch OD flared tubing with 1/8 inch NPT threaded ports, consistent with standard 45-degree SAE flare fitting applications in HVAC, plumbing, and gas distribution systems.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or gas fitter in accordance with applicable codes including the IPC, IFGC, or local mechanical code. Shut off all gas or fluid supply and depressurize the line before disassembling or installing any flare fitting. Use a calibrated flaring tool to ensure the tube end is properly seated and formed before tightening the flare nut — an improperly formed flare is the leading cause of joint failure. Do not over-torque the MNPT threads; apply a thread sealant rated for the service medium and follow the fitting manufacturer's thread engagement recommendations.
