Nibco PRECOUP34-JAR 3/4 in Copper Press Coupling 20 Pack

Product Description

The NIBCO PRECOUP34-JAR is a 3/4-inch copper press x press coupling with stop, sold as a 20-piece contractor pack. This fitting uses a press-connect joining method that eliminates open-flame soldering on the job site, making it suitable for wet or occupied spaces where torch work is restricted. The integral stop allows for consistent pipe insertion depth, reducing the chance of incomplete joints. Licensed plumbers and pipefitters install this fitting using a compatible press tool and jaw set. It is designed for use in potable water, hydronic heating, and general plumbing distribution systems.

This coupling is intended for residential and light commercial plumbing applications where 3/4-inch copper pipe is the specified distribution size. The press-connect design is commonly used in new construction and retrofit work, particularly in occupied buildings, healthcare facilities, and anywhere an open flame is impractical or code-restricted. The 20-pack quantity suits service contractors and installation crews working on multi-fixture or multi-zone projects.

Key Features

• Press x press end connections — no soldering or open flame required
• Integral pipe stop ensures full and consistent insertion depth before pressing
• 3/4-inch nominal size fits standard Type K, L, and M copper tubing
• 20-piece pack reduces per-unit cost for volume installations
• Copper construction provides corrosion resistance in potable water and hydronic systems

Compatibility

Designed as an OEM-style press fitting replacement for 3/4-inch copper press x press coupling applications in residential and commercial plumbing systems. Compatible press tool jaw specifications should be confirmed with the press tool manufacturer before installation.

Installation Notes

Installation requires a press tool and compatible 3/4-inch jaw or ring set rated for copper press fittings. Shut off and depressurize the water supply and relieve any residual pressure before cutting into the line. Work must comply with applicable local plumbing codes, which may reference IPC or similar model codes governing press-fit copper fittings. Do not attempt to press fittings on a live, pressurized line.
