Nibco PRESCOUPLS1 Copper Press Repair Coupling 1 in

Product Description

The NIBCO PRESCOUPLS1 is a 1-inch copper press repair coupling configured in a Press x Press end connection without a center stop. Designed for use with press-fit tooling systems, this coupling allows a technician to slide the fitting fully over a pipe and position it precisely during a repair — a critical advantage when cutting out a failed section of copper line. It is installed by licensed plumbers and pipefitters working on residential and light commercial potable water and hydronic systems.

This coupling is suited for repair scenarios where a standard coupling with a stop cannot be inserted into an existing run without additional pipe movement. The Press x Press configuration eliminates the need for soldering, open flame, or flux, making it practical in tight spaces or areas where fire safety is a concern. Typical applications include in-wall or under-slab copper pipe repair, hydronic heating distribution lines, and domestic hot and cold water systems.

Key Features

• No center stop design allows full-sleeve sliding for in-line pipe repairs
• Press x Press ends compatible with standard press-fit jaw tooling
• Copper construction for compatibility with copper pipe systems
• Eliminates open-flame soldering — suitable for fire-restricted work areas
• 1-inch nominal pipe size for common residential and light commercial runs

Compatibility

Designed as an OEM-style press fitting replacement for 1-inch copper pipe systems using press-fit connection technology.

Installation Notes

Installation requires a calibrated press tool with the appropriate 1-inch copper press jaw. Shut off and depressurize the water system and verify the line is fully drained before beginning the repair. Inspect pipe ends for roundness and burrs, and clean to the depth marks before pressing. Follow the fitting manufacturer's pressing sequence and verify each connection with a go/no-go inspection — an unpressed fitting will not be indicated by visual inspection alone.
