Nibco PRESCOUPLS34 Copper Press Repair Coupling 3/4 in

Product Description

The NIBCO PRESCOUPLS34 is a 3/4-inch copper press repair coupling designed for press-fit piping systems. It connects two sections of copper pipe using a press x press configuration and is built without an internal stop, allowing the fitting to slide freely over the pipe before being positioned for repair. This makes it well suited for inline pipe repairs where a standard coupling with a center stop cannot be inserted. Licensed plumbers and pipefitters install this fitting using a press tool with a compatible jaw set, eliminating the need for open flame or solder during the connection process.

This coupling is intended for residential and light commercial plumbing applications where copper press systems are specified. It is commonly used in potable water distribution, hydronic heating lines, and other copper piping installations where a fast, flame-free repair is required. The slide-style, no-stop design makes it the correct choice when replacing a damaged section of pipe without cutting back to an existing fitting end.

Key Features

• No internal stop allows the fitting to slide freely over pipe for mid-line repairs
• Press x press end configuration on both sides for tool-actuated, flame-free joining
• 3/4-inch nominal size fits standard 3/4-inch copper pipe
• Copper construction provides corrosion resistance suitable for potable water and hydronic systems
• Eliminates soldering, reducing labor time and fire-watch requirements

Compatibility

Designed as an OEM-style press repair coupling for 3/4-inch copper press piping systems. Compatible jaw sets and press tools from leading manufacturers are required for proper installation; verify jaw compatibility with your press tool before use.

Installation Notes

Installation must be performed by a licensed plumber or pipefitter familiar with press-fit joining systems. Shut off the water supply and depressurize the line before beginning any repair work. Ensure pipe ends are clean, deburred, and free of moisture before sliding the coupling into position. Use only a press tool and jaw set rated for the fitting size and material; do not use heat or solder with this fitting.
