Carrhill ST1 Socket Fusion Gas Mdpe Tee 1 Inch

Product Description

The CARRHILL ST1 is a 1-inch socket fusion tee designed for medium-density polyethylene (MDPE) gas distribution piping. This yellow-coded fitting is used to create branch connections in buried or aboveground natural gas and propane service lines. The socket fusion end configuration allows a licensed pipefitter or plumbing contractor to heat the pipe and fitting simultaneously using a socket fusion tool and join them without adhesives or mechanical fasteners. The yellow color coding identifies this fitting as gas-service rated, following standard industry color conventions for polyethylene gas piping.

This tee is suited for residential and light commercial gas distribution applications where MDPE pipe is the primary material. Typical installations include service line laterals, meter set connections, and branch runs from a main distribution line. The socket fusion joining method is common in underground gas piping systems where leak-free, pressure-rated joints are required. This fitting is installed by licensed gas contractors or journeymen plumbers qualified in polyethylene pipe fusion work.

Key Features

• 1-inch socket fusion ends for direct connection to MDPE gas pipe
• Yellow color coding identifies gas-service application per industry convention
• Fusion joining method produces a homogeneous, leak-resistant joint without adhesives
• MDPE construction offers flexibility and resistance to corrosion in buried service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch MDPE gas distribution piping systems using socket fusion joining methods.

Installation Notes

Installation must be performed by a licensed contractor qualified in polyethylene pipe fusion in accordance with applicable local codes and IFGC requirements. Shut off and verify that the gas supply is fully isolated and pressure is relieved before making any connections. Use a properly sized and calibrated socket fusion tool set to the correct heating temperature for MDPE per the pipe and fitting manufacturer guidelines. Inspect all fusion joints for a uniform, continuous bead before backfilling or pressurizing the system.
