The MERIT BRASS PCFA0300 is a lead-free press-by-female-iron-pipe (FIP) adapter designed for joining press-fit copper or copper-alloy piping systems to female threaded pipe connections. This fitting transitions a press-style connection to a standard FIP threaded port, allowing integration with valves, pumps, manifolds, and other threaded components without soldering or open flame. At 3 inches, it is suited for larger-diameter commercial and industrial plumbing runs. Licensed plumbers and pipefitters are the primary installers of this fitting type.
This adapter is used in potable water, hydronic heating, and mechanical room piping applications where press-fit systems connect to threaded equipment or assemblies. The 3-inch size is common in commercial buildings, institutional facilities, and light industrial settings where larger flow capacity is required. The lead-free construction meets regulatory requirements for use in systems carrying drinking water.
Designed as an OEM-style fitting for use in press-fit copper and copper-alloy piping systems that terminate to standard female NPT threaded connections in commercial and industrial plumbing installations.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water system fully before installing or removing any press fittings. Use only a compatible press tool and jaw set rated for the pipe diameter and fitting series being installed. Do not attempt to repress a fitting that has already been fully pressed.
