MCDONALD 4430-002 is a flexible gas riser designed to connect underground plastic gas distribution piping to above-ground gas appliances and meters. It transitions from 1-inch CTS (Copper Tube Size) to a 1-inch MPT (Male Pipe Thread) fitting, making it compatible with SDR12.5 plastic gas pipe with a 0.090-inch wall thickness. This riser is used in natural gas service installations where a flexible, durable transition from buried polyethylene pipe to a threaded service connection is required. Licensed gas piping contractors install this component as part of residential and light commercial gas service risers.\u003c\/p\u003e\u003cp\u003eThis riser is suited for residential and light commercial gas service applications where SDR12.5 polyethylene gas distribution pipe terminates at grade and transitions to a meter set or above-ground appliance connection. The 1-inch CTS x 1-inch MPT configuration is a common size for medium-volume gas service feeds. It is designed for use with 0.090-inch wall SDR12.5 gas plastic pipe and provides the flexible riser section needed to accommodate minor ground movement and thermal expansion at the service point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTransitions 1-inch CTS polyethylene gas pipe to 1-inch MPT threaded connection\u003c\/li\u003e\n\u003cli\u003eCompatible with SDR12.5 plastic gas pipe at 0.090-inch wall thickness\u003c\/li\u003e\n\u003cli\u003eFlexible construction accommodates minor ground movement and thermal cycling\u003c\/li\u003e\n\u003cli\u003eDesigned for natural gas service riser applications at meter sets and service entries\u003c\/li\u003e\n\u003cli\u003e1-inch MPT outlet fits standard gas meter and appliance threaded fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SDR12.5 plastic gas distribution pipe with a 0.090-inch wall thickness in 1-inch CTS sizing.

Shut off gas service and verify the line is depressurized before making any connections. Do not overtighten the MPT threaded connection; use an approved pipe thread sealant rated for gas service. Inspect all joints for leaks using an approved leak detection solution after restoring gas pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1 inch CTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1 inch MPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Standard\u003c\/strong\u003e: SDR12.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Wall Thickness\u003c\/strong\u003e: 0.090 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Material\u003c\/strong\u003e: Plastic (Polyethylene) Gas Distribution Pipe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: CTS x MPT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: A.Y.
