Anderson Metals 754046-0406 Brass Flare Connector 1/4in

Product Description

The ANDERSON METALS 754046-0406 is a lead-free brass flared tube connector designed to join 1/4 inch OD tubing to a 3/8 inch female NPT fitting using a 45-degree flare. The connector features a Flare x FNPT end configuration, making it a standard interface between soft copper or aluminum tubing and threaded pipe fittings. Rated at 1000 psi for both dynamic and static working pressure, this fitting is built for demanding service in gas, refrigeration, and fluid system applications. Plumbers, HVAC technicians, and gas fitters install this type of connector in both new construction and service work.

This connector is suited for residential and light commercial installations where flared tubing transitions to NPT-threaded components. Common applications include fuel gas lines, refrigerant piping, hydraulic circuits, and pneumatic systems that call for a reliable, pressure-rated flare fitting. The lead-free brass construction meets material requirements for potable water and fuel service where lead-free compliance is mandated.

Key Features

• Lead-free brass construction meets lead-free compliance requirements for fuel and water service
• 45-degree flare angle provides a leak-resistant metal-to-metal seal at the tube connection
• Flare x FNPT end configuration transitions 1/4 inch OD tubing to a 3/8 inch female NPT port
• 1000 psi maximum working pressure rating for both dynamic and static service
• NPT thread standard ensures compatibility with standard pipe fittings across trade applications
• Compact single-piece fitting with no gaskets or elastomers at the flare interface

Compatibility

Designed as an OEM-style replacement or direct-install fitting for systems using 1/4 inch OD flared tubing with a 3/8 inch female NPT connection point, conforming to NPT thread standards.

Installation Notes

Installation of flared fittings should be performed by a licensed plumber, HVAC technician, or gas fitter in accordance with applicable codes such as the IFGC, IPC, or NEC where electrical systems are adjacent. Before servicing, shut off the supply valve and verify the line is depressurized before disconnecting any fittings. Use a calibrated flaring tool to produce a clean, consistent 45-degree flare on the tubing end before seating the fitting. Do not overtighten the flare nut, as this can crack the flare seat and cause a leak.
