Anderson Metals 754046-0404 Brass Flare Tube Connector 1/4 in

Product Description

The ANDERSON METALS 754046-0404 is a lead-free brass flared tube connector designed for use in fluid and gas piping systems where a reliable flare-to-female NPT connection is required. The fitting accepts a 1/4-inch OD tube on the flare end and connects to a 1/4-inch FNPT port, using a 45-degree flare seat to form a leak-resistant mechanical seal without the need for solder or press tooling. Rated to 1000 psi working pressure in both static and dynamic service, this connector suits high-integrity applications in HVAC, refrigeration, plumbing, and fuel gas lines. Lead-free brass construction meets material requirements for potable water and medical gas service where applicable. Licensed plumbers and HVAC technicians are the typical installers.

This connector is suited for residential and light commercial installations where copper or compatible tubing is terminated at an NPT-threaded port. Common applications include connecting 1/4-inch refrigerant or fuel lines to valves, gauges, manifolds, and equipment ports with 1/4-inch female NPT inlets. The 45-degree flare geometry is the standard angle used across HVAC refrigerant circuits, fuel gas systems, and general fluid service in North America. The compact form factor makes it practical in tight equipment compartments and panel cutouts where space is limited.

Key Features

• Lead-free brass construction suitable for potable water and regulated fluid service
• 45-degree flare seat forms a secure mechanical seal without solder or adhesive
• 1000 psi maximum working pressure, static and dynamic
• Flare x FNPT end configuration connects copper OD tube to NPT-threaded ports
• 1/4-inch tube OD inlet paired with 1/4-inch female NPT outlet
• NPT thread standard ensures broad compatibility with standard fittings and valves

Compatibility

Designed as an OEM-style replacement or service fitting for piping systems using 1/4-inch OD flared copper tubing terminating at 1/4-inch female NPT ports, common in HVAC, refrigeration, plumbing, and fuel gas applications.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable codes, including IPC and IFGC requirements for the service type. Shut off all fluid or gas supply and depressurize the line before disassembly or fitting installation. Flare the tubing to the correct 45-degree angle using a calibrated flaring tool before seating the fitting; do not overtighten, as brass threads and flare seats can be damaged by excessive torque. Apply thread sealant rated for the specific service fluid to the NPT threads only, keeping the flare seat dry and free of contamination.
