Harco 69-3110BB 3/4 Inch Socket Fusion Hdpe Tee Black

Product Description

The HARCO 69-3110BB is a 3/4-inch socket fusion HDPE tee fitting designed for water distribution piping systems. This black high-density polyethylene tee connects three pipe runs at a single junction using the socket fusion joining method, which creates a monolithic, leak-resistant bond without mechanical fasteners or solvent cements. The fitting is suited for buried and above-ground potable water and irrigation applications where corrosion resistance and long service life are required. Licensed plumbers and water system installers work with this fitting type in residential and light commercial projects.

This tee is intended for use in 3/4-inch HDPE piping systems carrying water, including potable water supply lines, irrigation mainlines, and geothermal loop fields. Socket fusion fittings like the 69-3110BB are commonly installed where a branch takeoff is needed along a straight run. The black coloring indicates a carbon-black UV stabilizer formulation, making this fitting appropriate for applications with incidental sun exposure prior to burial or final installation.

Key Features

• 3/4-inch socket fusion end configuration for all three ports
• HDPE construction provides corrosion resistance and flexibility under ground movement
• Black carbon-black compound provides UV stabilization for outdoor staging and shallow-buried runs
• Socket fusion joint eliminates mechanical connections and associated leak points
• Suitable for potable water, irrigation, and geothermal piping systems

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 3/4-inch HDPE socket fusion piping systems used in water distribution applications.

Installation Notes

Socket fusion fittings require a dedicated socket fusion tool set to heat both the fitting socket and pipe end simultaneously to the correct temperature before joining. Installers should follow ASTM F2620 procedures and the tool manufacturer's heat time and cooling hold time guidelines for the pipe diameter and ambient temperature. Shut off and depressurize the water system before cutting into any existing line. Socket fusion joints must not be pressurized until the joint has fully cooled per procedure requirements.
