Carrhill PT112 Gas Straight Transition Fitting 1.5 in Mipt

Product Description

The CARRHILL PT112 is a straight transition fitting designed to connect male iron pipe thread (MIPT) steel pipe to medium-density polyethylene (MDPE) gas distribution tubing. This fitting bridges metallic and plastic piping systems in natural gas and propane distribution applications. The steel MIPT end threads onto a standard iron pipe connection, while the MDPE end accepts polyethylene gas pipe for a secure, leak-resistant transition. Licensed plumbers and gas fitters install this type of fitting during service lateral installations, meter set assemblies, and underground-to-aboveground transitions where steel and plastic piping meet.

This transition fitting is suited for residential and light commercial gas piping systems where MDPE polyethylene pipe transitions to threaded steel pipe. Typical applications include service line connections at the meter, underground PE gas line terminations, and distribution system tie-ins. The 1.5-inch nominal size accommodates higher-flow residential or small commercial gas loads. Installation is performed by licensed gas fitters or plumbers in compliance with local fuel gas codes and utility requirements.

Key Features

• 1.5-inch MIPT steel inlet connects directly to standard iron pipe thread fittings
• MDPE outlet accepts medium-density polyethylene gas distribution tubing
• Straight configuration simplifies inline transitions without offset or bending
• Steel construction on the threaded end provides mechanical durability at the connection point
• Designed for natural gas and propane gas distribution piping systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for gas piping systems requiring a transition between 1.5-inch MIPT steel pipe and MDPE polyethylene gas tubing.

Installation Notes

Installation must be performed by a licensed plumber or gas fitter in accordance with the International Fuel Gas Code (IFGC) and applicable local codes. Shut off the gas supply at the meter or service valve and verify zero pressure before beginning work. Apply appropriate thread sealant rated for gas service to the MIPT threads before making the steel connection. The MDPE end should be joined using a compatible mechanical fitting or heat fusion method as specified by the tubing manufacturer and local utility standards.
