The NIBCO PRESCOUP12 is a 1/2-inch copper press-style coupling with an integrated stop, designed for joining copper tubing in pressurized water and hydronic piping systems. The stop shoulder positions the tubing consistently during assembly, reducing the chance of under-insertion before the fitting is pressed. This fitting installs without open flame, making it suitable for work in environments where torch use is restricted or impractical. Licensed plumbers and pipefitters use press fittings as a faster, cleaner alternative to soldered connections in both new construction and retrofit applications.
This coupling is intended for residential and light commercial plumbing, radiant heating, and hydronic distribution systems wherever 1/2-inch copper tubing is run. The press-by-press end configuration allows straight inline connections between two copper tube sections. It is well suited for tight spaces, occupied buildings, and any situation where soldering is not preferred. Installation requires a compatible press tool and the appropriate jaw set for the fitting size and series.
Designed as an OEM-style press fitting for use with standard 1/2-inch copper tubing in residential and commercial plumbing and hydronic piping systems. Requires a compatible press tool and jaw set rated for this fitting series.
Installation must be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before beginning work. Ensure the copper tubing is fully inserted to the stop before pressing, and verify the sealing element is properly seated. Use only a press tool and jaw set approved for this fitting series to achieve a proper seal.
