Nibco PREST12 Copper Press Tee 1/2 Inch P X P X P

Product Description

The NIBCO PREST12 is a 1/2-inch copper press tee configured in a P x P x P end connection pattern, meaning all three ports accept press-style fittings. This tee is designed for use in pressurized water distribution and hydronic systems where a branch takeoff is required. The press connection eliminates open-flame soldering, making installation faster and safer in confined or fire-sensitive spaces. Licensed plumbers and mechanical contractors install this fitting during new construction and retrofit work on copper piping systems.

This fitting is suited for residential and light commercial plumbing applications, including domestic cold and hot water supply lines and closed-loop hydronic heating systems. The all-press configuration allows the installer to make three connections using a press tool without soldering, which reduces labor time and eliminates the need for a hot-work permit in many jurisdictions. It is a direct fit wherever a 1/2-inch copper tee branch is required in a press-fit system.

Key Features

• 1/2-inch nominal size fits standard copper tubing
• P x P x P end connections on all three ports for full press-tool installation
• No-flame installation eliminates open-fire hazards and hot-work permitting in many jurisdictions
• Copper construction provides corrosion resistance in potable water and hydronic applications
• Tee configuration allows a straight run with a perpendicular branch takeoff

Compatibility

Designed as an OEM-style press fitting compatible with standard 1/2-inch copper tubing in press-fit plumbing systems.

Installation Notes

Installation requires a calibrated press tool with a jaw set rated for the fitting size and connection type. Shut off and depressurize the water supply and drain the line before making any connections. Verify that the copper tubing is cut square, deburred, and inserted to the full depth mark before pressing. Work should comply with applicable local plumbing codes and ASTM standards for copper press fittings.
