The ANDERSON METALS CORP 714039-08 is a 0.5-inch flare plug designed to cap and seal flare fittings in gas and refrigeration piping systems. This fitting meets the lead-free requirements of Public Law 111-380, making it compliant for use in potable water and applicable plumbing installations. Sold in a carded pack of 10 individual units, the 714039-08 is a standard trade-supply item stocked for plumbers, HVAC technicians, and pipefitters who need a reliable, code-compliant cap for flare connections during service, testing, or system modifications.
This flare plug is suited for residential and light commercial applications where a 0.5-inch flare fitting must be sealed off. Common use cases include capping unused ports on manifolds, isolating sections of refrigerant or gas lines during repair, and sealing system openings during pressure testing. The carded retail packaging makes it practical for both shop inventory and field service kits.
Designed as an OEM-style replacement and service fitting for systems using standard 0.5-inch flare connections in plumbing, HVAC, and gas piping applications.
Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local codes, the International Plumbing Code (IPC), or the International Fuel Gas Code (IFGC). Always depressurize and isolate the line before removing or installing flare fittings. Use an appropriately sized flare wrench to avoid deforming the fitting seat. Do not overtighten, as this can damage the flare seat and cause leaks.
