The NIBCO PRESADCMIP1 is a 1-inch copper press-by-male-IPS adapter designed for joining press-fit copper piping systems to male-threaded connections. This fitting transitions a press-end copper connection to a male NPT thread, allowing integration with valves, fixtures, or threaded pipe sections without soldering or open flame. The press-end connection uses a jaw-pressed sealing mechanism, making it well-suited for installations in occupied spaces or areas where torch work is restricted. Licensed plumbers and pipefitters install this adapter in both new construction and retrofit applications.
This adapter is appropriate for residential and light commercial plumbing systems where copper press technology is in use. It is designed for use with 1-inch press-fit copper tubing and transitions to a 1-inch male iron pipe size (IPS) thread. Typical install scenarios include connecting press-copper supply lines to threaded shutoff valves, manifolds, or equipment inlets. It is part of the NIBCO PC604 press adapter product family.
Designed as an OEM-style replacement and standard fitting for 1-inch copper press piping systems connecting to male IPS threaded components. Refer to system design specifications to confirm press-end compatibility with your press tool and ring type.
Installation should be performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before pressing the fitting. Use a calibrated press tool with the correct jaw size for 1-inch copper press fittings and verify the fitting is fully seated before pressing. Do not use thread sealant on press-end connections; apply appropriate thread sealant or PTFE tape to the male NPT threads only.
