Anderson Metals 754040-10 Brass Flared Tube Cap 5/8 in 45 Deg

Product Description

The ANDERSON METALS 754040-10 is a lead-free brass flared tube cap designed to seal the open end of a 5/8 inch OD flared tube. It uses a 45-degree flare connection to create a secure, pressure-rated seal without the need for solder or adhesive. Rated for up to 650 psi working pressure in both static and dynamic applications, this cap is built for demanding service environments. The lead-free brass construction meets current drinking water safety standards, making it suitable for potable water systems as well as refrigeration and HVAC lines. Plumbers, HVAC technicians, and pipefitters use this cap to terminate or pressure-test flared tube runs.

This cap is used wherever a 5/8 inch OD flared line needs to be capped off cleanly, whether for system commissioning, pressure testing, or permanent termination. Typical applications include residential and light commercial plumbing, refrigerant line sets, fuel gas distribution, and hydronic systems where flare fittings are the specified connection type. The 45-degree flare angle conforms to standard flare fitting geometry used widely across HVAC and plumbing trades.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians. Shut off and depressurize the system before installing or removing any flare fitting. Use an appropriate flare nut wrench to seat the cap without over-torquing, which can distort the flare seating surface. Verify the mating flare surface is clean and free of burrs or damage before making the connection.
