Nibco PREST112 Copper Press Tee 1-1/2 Inches

Product Description

The NIBCO PREST112 is a copper press tee fitting designed for use in pressurized plumbing and hydronic piping systems. It features a press-style connection on all three ports, eliminating the need for open-flame soldering during installation. The fitting measures 1-1/2 inches on each port in a P x P x P configuration, making it suitable for branching supply or return lines. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit applications where torch-free joining is preferred or required.

This press tee is suited for residential and light commercial plumbing, radiant heating, and hydronic systems where copper piping is the specified material. The press connection style is commonly used in mechanical rooms, tight spaces, or fire-rated areas where open-flame work is restricted. All three ports accept standard press-style tooling compatible with 1-1/2 inch copper fittings.

Key Features

• Press connection on all three ports eliminates open-flame soldering
• 1-1/2 inch P x P x P configuration for branch-line installations
• Copper construction for corrosion resistance in potable and hydronic systems
• Compatible with standard press-jaw tooling for 1-1/2 inch copper

Compatibility

Designed as an OEM-style press fitting for use in 1-1/2 inch copper piping systems using press-style joining tools.

Installation Notes

Installation requires a calibrated press tool with the appropriate 1-1/2 inch copper press jaw — do not substitute crimp or PEX tooling. Shut off and depressurize the water or hydronic system fully before cutting into existing lines. Work must comply with local plumbing codes and applicable IPC requirements. Inspect the pipe end for burrs and ensure it is fully seated in the fitting socket before pressing.
