Anderson Metals 754039-06 Brass Flared Tube Plug 3/8 in

Product Description

The ANDERSON METALS 754039-06 is a lead-free brass flared tube plug designed to seal off a 3/8-inch OD flare connection in refrigeration, HVAC, and plumbing tubing systems. Machined from lead-free brass, this plug seats against a standard 45-degree flare to create a pressure-tight termination point. It is rated for up to 1000 psi working pressure in both dynamic and static service conditions. Plumbers, HVAC technicians, and refrigeration mechanics install this fitting when capping an unused flare port or closing a branch line during system modification or maintenance. Its compact size and reliable flare seal make it a practical single-piece termination solution for copper tubing applications.

This flared tube plug is suited for residential and light commercial HVAC systems, refrigeration lines, and plumbing tubing assemblies that use standard 45-degree flare fittings. Common applications include capping off unused service ports, sealing branch lines during system retrofits, and terminating open flare connections during staged installations. The 3/8-inch tube OD sizing aligns with widely used copper tubing in split-system refrigerant circuits and hydronic distribution lines.

Key Features

• Lead-free brass construction meets current plumbing material standards
• 45-degree flare end connection seats against standard flare fittings for a pressure-tight seal
• Rated to 1000 psi working pressure in both static and dynamic service
• 3/8-inch tube OD sizing fits common copper tubing used in HVAC and refrigeration
• Compact single-piece design with no moving parts or additional hardware required

Compatibility

Designed as an OEM-style replacement and standard service fitting for 45-degree flare tube connections with a 3/8-inch outside diameter, as commonly found in residential and light commercial HVAC, refrigeration, and plumbing tubing systems.

Installation Notes

Installation is performed by licensed plumbers or HVAC-refrigeration technicians. Before installing, isolate and depressurize the line being capped and recover any refrigerant in accordance with EPA Section 608 requirements where applicable. Thread the plug onto the flare fitting by hand to confirm seating, then tighten with a flare nut wrench to achieve a leak-free seal without over-torquing the flare. Verify system integrity with a pressure or leak test after installation.
