Nibco PRESCOUPLS3 Copper Press Repair Coupling 3 in

Product Description

The NIBCO PRESCOUPLS3 is a 3-inch copper press repair coupling designed for press-fit piping systems. It features a press x press end configuration with no internal stop, allowing the fitting to slide freely along the pipe for true repair-style installation. This makes it well suited for in-line pipe repairs where a standard coupling with a stop cannot be inserted. Licensed plumbers and pipe fitters install this fitting using a compatible press tool and jaw set rated for the pipe diameter.

This coupling is used in residential and commercial plumbing systems where copper press technology is specified. The no-stop design is the defining feature for repair applications — the fitting slides over the existing pipe, is repositioned over the joint, and is then pressed to create a permanent, leak-tight connection. It is commonly used for segment replacement on water supply lines, hydronic heating systems, and similar copper piping applications.

Key Features

• 3-inch press x press end connections for tool-based press fitting installation
• No internal stop allows free axial movement along the pipe for repair scenarios
• Copper construction offers corrosion resistance and long service life in plumbing systems
• Compatible with standard press tooling and jaw sets sized for 3-inch copper pipe
• Provides a permanent, solder-free connection once pressed

Compatibility

Designed as an OEM-style replacement and repair fitting for 3-inch copper press piping systems. Compatible with standard copper press tooling and jaw sets sized for 3-inch pipe.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipe fitter in accordance with applicable local plumbing codes and ASME B16.18 or manufacturer press system requirements. Shut off and depressurize the water supply line and verify the pipe is dry before pressing. Use only a press tool and jaw set rated and approved for the specific press fitting system — do not attempt to install with standard hand tools. Inspect the pressed joint visually for proper seating before returning the system to service.
