Nibco PRESTRED1121 Copper Press Tee 1x1/2x1 Pxpxp

Product Description

The NIBCO PRESTRED1121 is a copper press tee fitting designed for use in pressurized water and hydronic piping systems. It connects three pipe runs in a tee configuration using a press-fit joining method, eliminating the need for open flame or soldering during installation. The fitting features a reducing center outlet, with 1 inch connections on the run ends and a 1/2 inch connection on the branch outlet, all three ends using press-type connections. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit applications.

This press tee is suited for residential and light commercial plumbing, radiant heating, and hydronic distribution systems where copper piping is specified. The press connection method is particularly useful in occupied spaces or areas where torch work is restricted. All three connections are press-type, noted as P x P x P, making the fitting compatible with standard press tooling used on copper pipe.

Key Features

• Reducing tee configuration: 1 inch run x 1 inch run x 1/2 inch branch outlet
• All-press connection ends (P x P x P) — no soldering or torch required
• Copper construction for corrosion resistance in water and hydronic service
• Suitable for pressurized closed-loop and domestic water piping systems

Compatibility

Designed as an OEM-style press fitting replacement or new-install component for copper piping systems using standard press-fit tooling on 1 inch and 1/2 inch copper pipe.

Installation Notes

Installation should be performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off and depressurize the water supply and ensure the pipe is dry before pressing. Use a calibrated press tool with the correct jaw size for each connection diameter — 1 inch jaws for the run ends and 1/2 inch jaws for the branch. Inspect each pressed connection for proper seating before restoring system pressure.
