Anderson Metals 754056-0604 Brass Flared Tube Union 3/8x1/4

Product Description

The ANDERSON METALS 754056-0604 is a lead-free brass flared tube union designed to join two flared tubing runs in a single inline connection. It features a 45-degree flare angle with flare-by-flare end connections, accepting a 3/8-inch tube OD on one end and a 1/4-inch tube OD on the other. The union configuration allows either side of the tubing to be disconnected independently, which is useful during service calls. Rated at 1000 psi for both dynamic and static working pressure, this fitting is suited for refrigeration lines, fuel gas, and other pressure-sensitive fluid systems where lead-free construction is required by code.

This fitting is used in residential and light commercial applications wherever a flared tube union is needed to connect two different tube sizes. Common install scenarios include refrigerant line connections, LP or natural gas supply lines, and hydraulic or compressed-air tubing assemblies. Its compact size and standard 45-degree flare geometry make it compatible with flare tooling found in any HVAC or plumbing service van. Licensed HVAC technicians and plumbers are the primary installers.

Key Features

• Lead-free brass construction meets low-lead compliance requirements for potable and non-potable systems
• 45-degree flare angle on both ends conforms to standard SAE flare tooling
• Reducer union design accepts 3/8-inch OD tube on one end and 1/4-inch OD tube on the other
• Rated to 1000 psi working pressure, both dynamic and static
• Flare-by-flare end connections allow full disconnection on either side without cutting tubing

Compatibility

Designed as an OEM-style replacement or service fitting for any system using standard 45-degree SAE flare connections with 3/8-inch and 1/4-inch tube OD tubing.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with applicable mechanical and plumbing codes. Depressurize and evacuate the system before disconnecting any existing flare fittings. Use a calibrated flare tool to produce a clean, consistent 45-degree flare seat on both tube ends before assembly. Hand-tighten the flare nuts before applying a final wrench turn to avoid cross-threading or over-torquing the brass seats.
