Anderson Metals 754040-08 Brass Flared Tube Cap 1/2 in 45 Deg

Product Description

The ANDERSON METALS 754040-08 is a lead-free brass flared tube cap designed to terminate a 1/2-inch OD flare connection. It seats against a 45-degree flare seat to create a pressure-tight seal, blocking flow at the end of a copper or compatible tubing run. Rated for a maximum working pressure of 750 psi in both static and dynamic service, this cap is built for demanding applications in HVAC refrigerant lines, plumbing, and gas distribution systems. Licensed plumbers, HVAC technicians, and pipefitters install this fitting when capping an unused branch or securing an open line during service or system modification.

This fitting is suited for residential and light commercial installations where a 45-degree flare end connection is the specified joint type. Common scenarios include capping refrigerant service ports, terminating unused copper tubing branches in plumbing rough-ins, and sealing lines during staged construction or system expansion. Its lead-free brass construction meets requirements for potable water applications where lead-free materials are mandated by code.

Key Features

• Lead-free brass construction meets lead-free mandates for potable water service
• 45-degree flare seat provides a reliable metal-to-metal pressure seal
• Rated to 750 psi maximum working pressure, static and dynamic
• Fits 1/2-inch OD tubing flared to the standard 45-degree angle
• Compact cap profile for use in tight spaces within mechanical chases or equipment cabinets

Compatibility

Designed as an OEM-style replacement or standard service fitting for systems using 1/2-inch OD copper or compatible tubing with a 45-degree flare end connection.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician. De-pressurize and evacuate the line before removing any existing fitting or installing this cap. Inspect the tube flare for cracks, out-of-round deformation, or scoring before seating the cap, as a damaged flare will not seal reliably at rated pressure. Tighten with a flare-nut wrench to the fitting flats only — do not use pipe wrenches that can distort the cap body. Follow applicable sections of the IFGC, IPC, or local mechanical code for pressure testing after installation.
