Anderson Metals 754046-0504 Brass Flare Connector 5/16in

Product Description

The ANDERSON METALS 754046-0504 is a lead-free brass flared tube connector designed for use in refrigeration, HVAC, and fluid-handling systems where a reliable flare-to-female NPT transition is required. The fitting features a 45-degree flare on one end and a female NPT thread on the other, accepting 5/16-inch OD tubing. Constructed from lead-free brass, this connector meets potable-water and modern plumbing material standards. It is rated for up to 1000 psi working pressure in both static and dynamic service conditions, making it suitable for higher-pressure line sets and refrigerant or gas distribution applications. HVAC technicians and licensed plumbers are the primary installers of this fitting type.

This connector is used in residential and light commercial HVAC systems, refrigeration line sets, compressed air distribution, and plumbing applications requiring a transition from flared copper tubing to a female NPT port. The 45-degree flare angle is the standard configuration used throughout North American HVAC and refrigeration installations. It is appropriate for copper tubing sized at 5/16-inch OD and pairs with standard 45-degree flare nuts and NPT-threaded ports on equipment, manifolds, and control valves.

Key Features

• Lead-free brass construction meets current material requirements for potable water and HVAC applications
• 45-degree flare end accepts standard 5/16-inch OD copper tubing
• Female NPT (FNPT) threaded end for connection to NPT-ported equipment or valves
• Rated to 1000 psi maximum working pressure, both static and dynamic
• Compact single-piece connector design suitable for tight installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for HVAC, refrigeration, and plumbing systems using 5/16-inch OD copper tubing with 45-degree flare connections and 1/4-inch female NPT ports.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. De-energize the system and relieve all line pressure before removing or installing any fittings. Ensure the copper tubing is properly flared to a 45-degree angle using a calibrated flaring tool before seating the fitting. Apply an appropriate thread sealant to the NPT end per local plumbing or mechanical code requirements, and do not overtighten, as brass fittings are subject to thread damage from excessive torque.
