Nibco PREST1 Copper Press Tee 1 Inch P X P X P

Product Description

The NIBCO PREST1 is a copper press tee designed for use in pressurized plumbing and hydronic systems. This fitting connects three copper pipe runs in a tee configuration using a press-fit joining method, eliminating the need for open flame soldering. All three ports are press-type connections (P x P x P), allowing fast, tool-based assembly suited to commercial and residential mechanical rooms. Licensed plumbers and pipefitters working in environments where torch work is restricted or impractical will find this fitting a practical solution for new installation and retrofit work.

The PREST1 is sized for 1-inch copper pipe and is appropriate for potable water supply lines, hydronic heating loops, and chilled water distribution systems. Press fittings of this type are commonly used in commercial plumbing, multi-family residential construction, and mechanical rooms where code or site conditions prohibit open-flame work. The press connection method is compatible with standard press tooling available from major tool manufacturers.

Key Features

• All-copper construction for corrosion resistance and long service life in plumbing and hydronic applications
• Press-fit connections on all three ports eliminate open-flame soldering at the joint
• 1-inch nominal size accommodates standard 1-inch copper pipe
• Tee configuration (P x P x P) supports branch takeoffs in supply or return lines
• Suitable for pressurized potable water and hydronic systems

Compatibility

Designed as an OEM-style press fitting for use with standard 1-inch copper pipe in residential and commercial plumbing and hydronic piping systems.

Installation Notes

Installation must be performed by a licensed plumber or pipefitter using a compatible press tool with the correct jaw set for 1-inch copper press fittings. Shut off and depressurize the water system and drain affected lines before working on any fitting. Verify that the pipe end is clean, deburred, and fully inserted to the depth mark before pressing. Follow applicable local plumbing codes and ASTM standards for copper piping systems.
