The NIBCO PRESADCFIP12-JAR is a copper press x female adapter designed for use in press-fit plumbing systems. This fitting connects a press-end pipe to a female threaded port, eliminating the need for open-flame soldering at the joint. It is sized at 1/2 inch and sold in a 20-count contractor pack, making it well suited for multi-unit residential or light commercial plumbing jobs. Licensed plumbers and pipefitters use this adapter when transitioning from press-fit copper lines to threaded valves, gauges, or equipment connections.
This adapter is intended for residential and light commercial potable water and hydronic heating systems where 1/2-inch press-fit copper connections are specified. The press end accepts standard Type K, L, or M copper tubing, and the female threaded end accommodates NPT fittings. The 20-pack jar format reduces trip-to-supply-house frequency on larger jobs and rough-in work where this size adapter is commonly installed in volume.
Designed as an OEM-style press-fit copper adapter for use with standard 1/2-inch copper press-fit plumbing systems.
Installation requires a calibrated press tool with the appropriate 1/2-inch jaw set for copper press fittings. Shut off and depressurize the water supply and verify the pipe is dry before pressing. Work must comply with applicable local plumbing codes and manufacturer press-fit installation guidelines. Do not use a torch or heat source on the press end of the fitting.
