Anderson Metals 754014-06 Brass Flare Tube Nut 3/8 in 45 Deg

Product Description

The ANDERSON METALS 754014-06 is a lead-free brass flare tube nut designed for use with 3/8-inch OD tubing and a 45-degree flare angle. This fitting nut secures a flared tube end to a mating flare fitting, creating a leak-resistant mechanical connection without solder or adhesive. Built from lead-free brass, it meets regulatory requirements for potable water and other sensitive fluid systems. The 754014-06 is rated for up to 1000 psi working pressure in both static and dynamic service conditions, making it suitable for a range of plumbing, refrigeration, and gas applications where flare fittings are the specified connection type.

This flare tube nut is used in residential and light commercial installations wherever 45-degree flare connections are required. Common applications include copper tubing runs in refrigeration lines, LP and natural gas distribution piping, and potable water systems. Plumbers, HVAC technicians, and gas fitters install this type of fitting nut when assembling or servicing flare-type tube connections on valves, manifolds, service ports, and appliance supply lines.

Key Features

• Lead-free brass construction meets requirements for potable water contact applications
• 45-degree flare angle compatible with standard SAE flare fittings
• Rated to 1000 psi working pressure, static and dynamic
• Fits 3/8-inch OD tubing — no solder or thread sealant required at the flare joint
• Compact form factor suitable for tight installation spaces

Compatibility

Designed for use with 3/8-inch OD tubing and standard 45-degree SAE flare fittings. Verify flare angle and tube OD match the mating fitting before installation.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or gas fitters depending on the application. Shut off and depressurize the line before disassembling or assembling any flare connection. The tube end must be properly flared to the correct 45-degree angle using a calibrated flaring tool before threading on the nut. Hand-tighten first, then use a wrench to achieve a snug, leak-free seat — do not overtighten, as brass flare fittings can crack or distort the flare seat.
