Anderson Metals 754020-0806 Brass Flared Tube Nut 1/2x3/8

Product Description

The ANDERSON METALS 754020-0806 is a lead-free brass flared tube nut designed for use in flare-type compression fittings on copper and compatible tubing systems. It mates with 45-degree flare fittings, accepting a 1/2-inch to 3/8-inch tube outside diameter range. The nut is manufactured from lead-free brass, meeting modern potable water and plumbing code requirements for low-lead content. It carries a maximum working pressure of 750 psi under both dynamic and static conditions. Plumbers, HVAC technicians, and gas-line installers use this fitting type when making leak-resistant mechanical joints without soldering or adhesives.

This flared tube nut is suited for residential and light commercial plumbing, refrigeration, and gas supply applications where 45-degree flare connections are specified. It is appropriate for use on soft copper tubing and other compatible tube materials at the listed OD sizes. The fitting is typically found in water supply lines, propane and natural gas connections, and refrigerant-side plumbing where flare joints are the required connection method per applicable codes.

Compatibility

Designed as an OEM-style replacement or service fitting for standard 45-degree flare connections on 1/2-inch to 3/8-inch outside diameter copper and compatible tubing in plumbing, HVAC, and gas supply systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC or gas technician in accordance with applicable local codes, including IPC and IFGC requirements for flare fittings. Shut off the gas or water supply and relieve system pressure completely before removing or installing any flare fitting. Use an appropriately sized flaring tool to ensure the tube end is properly prepared before seating the nut — a damaged or improperly flared tube end is a leading cause of joint leakage. Do not overtighten; use a backup wrench on the fitting body to prevent body rotation and tubing stress.
