Carrhill ST34 Socket Fusion Gas Mdpe Tee 3/4 Inch

Product Description

The CARRHILL ST34 is a 3/4-inch socket fusion tee designed for medium-density polyethylene (MDPE) gas distribution piping systems. This yellow-coded fitting is used to create branch connections in underground gas service lines, joining MDPE pipe at a tee intersection using the socket fusion joining method. Socket fusion creates a permanent, pressure-rated bond without mechanical fasteners or adhesives. The yellow color identifies the fitting as gas-service rated, distinguishing it from water or other utility piping. Installation is performed by licensed gas piping contractors working on residential or light commercial gas distribution systems.

The ST34 is suited for underground natural gas and propane distribution piping where MDPE pipe is the specified material. Socket fusion fittings in this size range are commonly used in gas service lateral installations, meter set connections, and yard line distribution runs. The 3/4-inch size is a standard service size for residential gas supply piping. This fitting is installed where a branch outlet is required off a main gas distribution run.

Key Features

• Yellow color coding identifies fitting as gas-service rated MDPE material
• Socket fusion joining method creates a permanent, leak-resistant connection without mechanical fasteners
• 3/4-inch tee configuration allows branch connections in gas distribution piping
• MDPE construction provides flexibility and corrosion resistance suitable for underground installation
• Order increment of 1 allows single-unit purchasing

Compatibility

Designed as an OEM-style replacement fitting for 3/4-inch MDPE gas distribution piping systems joined by socket fusion methods.

Installation Notes

Socket fusion gas fittings must be installed by a qualified gas piping contractor in accordance with applicable codes including IFGC and local utility requirements. Shut off and verify zero gas pressure in the line before cutting or joining any fitting. Socket fusion requires proper heating tools sized for the pipe and fitting diameter — use of incorrect tool temperatures or dwell times can result in a defective joint. Underground installations must meet depth and bedding requirements as specified by local jurisdiction and utility standards.
