Carrhill PT114 Gas Transition Fitting 1.25in Mipt Steel X Mdpe

Product Description

The CARRHILL PT114 is a straight transition fitting designed to connect 1.25-inch male iron pipe thread (MIPT) steel pipe to medium-density polyethylene (MDPE) gas distribution pipe. This fitting provides a reliable mechanical transition between metallic and plastic pipe materials in natural gas and propane distribution systems. Licensed plumbers and gas fitters install this type of fitting at service entry points, meter sets, and underground-to-aboveground transitions where the piping material changes. The steel MIPT end threads onto a valve, riser, or steel pipe, while the MDPE end accepts the plastic service line.

This fitting is suited for residential and light commercial gas service applications where a durable, code-acceptable transition between steel and MDPE piping is required. Common installation scenarios include outdoor meter sets, curb-to-structure gas runs, and retrofit connections where an existing steel system ties into a newer plastic distribution line. Installation typically occurs at or near grade level in gas service entry assemblies.

Key Features

• Straight transition design connects 1.25-inch MIPT steel pipe directly to MDPE gas pipe
• Steel construction on the threaded end provides mechanical strength at connection pointsMDPE-compatible end supports fusion or mechanical joining to plastic gas distribution pipe
• Single-piece straight configuration simplifies installation and reduces potential leak points
• Sized for 1.25-inch service lines common in residential and light commercial gas systems

Compatibility

Designed as an OEM-style replacement transition fitting for 1.25-inch MIPT steel to MDPE gas piping assemblies in residential and light commercial natural gas and propane distribution systems.

Installation Notes

Installation must be performed by a licensed plumber or certified gas fitter in accordance with the International Fuel Gas Code (IFGC) and all applicable local codes. Shut off gas supply and verify zero pressure before disassembling any existing piping. Apply approved thread sealant rated for gas service to all MIPT connections. Pressure-test the completed assembly per local code requirements before returning the system to service.
