Nibco PREST3 Copper Press Tee 3 Inches P X P X P

Product Description

The NIBCO PREST3 is a 3-inch copper press tee configured with three press-style end connections (P x P x P). It is designed for use in pressurized water distribution and hydronic piping systems where soldering or open-flame work is not practical or permitted. The press connection system allows technicians to make a permanent, leak-tested joint using a compatible pressing tool without heat, flux, or filler metal. This fitting is well suited for commercial and residential plumbing and mechanical installations handled by licensed plumbers and pipefitters.

This fitting is used in cold and hot water supply piping, hydronic heating and cooling distribution, and in-building mechanical systems where 3-inch copper press connections are specified. Press fittings are common in occupied building retrofits, hospitals, schools, and other facilities where open-flame work is restricted. The tee configuration allows a branch takeoff from a straight run of copper pipe at the same nominal size on all three ports.

Key Features

• 3-inch nominal size on all three ports for full-flow branch connections
• Press-style end connections eliminate the need for soldering or open flame
• Copper construction provides corrosion resistance in potable and non-potable water systems
• Compatible with standard press-fitting pressing tools used in commercial mechanical work
• Equal tee configuration supports branch takeoffs at full pipe diameter

Compatibility

Designed as an OEM-style press fitting for use with 3-inch copper press-connect piping systems in residential and commercial plumbing and mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B16.22 standards. Depressurize and drain the system before cutting into any existing piping. Use only a manufacturer-approved pressing tool with the correct jaw size for 3-inch press fittings. Verify that the pipe end is clean, deburred, and fully inserted to the pipe stop before pressing.
