Product Lines

Home-Flex CSST

Home-Flex CSST is a corrugated stainless steel tubing system designed for interior natural gas and propane distribution in residential and light commercial applications. The flexible construction allows the tubing to be routed through walls, floors, and ceilings without the elbow fittings required by rigid black iron pipe. Home-Flex CSST is available in 1/2-inch, 3/4-inch, and 1-inch sizes and comes in coil lengths of 25 feet, 75 feet, and 250 feet. The system includes a complete line of brass manifold tees, end fittings, and termination fittings for connecting to appliances and equipment.

Home-Flex CSST Brass Fittings and Accessories

Home-Flex brass fittings and accessories are designed and tested to work with Home-Flex CSST tubing. The fitting line includes brass male and female adapters, end fittings, manifold tees, and appliance connectors in standard pipe thread sizes. The quick-connect fitting design reduces installation time compared to traditional threaded connections on rigid pipe systems. Home-Flex CSST with its compatible brass fitting line provides a complete system from the gas meter to the appliance, with all components engineered to work together under the same listing.

Home-Flex Underground Gas Pipe

Home-Flex Underground is a medium-density polyethylene gas pipe system for below-grade exterior gas service lines connecting the utility meter to the structure. Home-Flex Underground pipe is manufactured in compliance with ASTM D2513 for gas distribution piping applications. The flexible MDPE construction allows the pipe to be pulled and installed through directional drilling or open trench without the numerous fittings required by rigid pipe. Home-Flex Underground pipe is not approved for use inside buildings, under buildings, or above grade. The product is used by plumbers and gas contractors for yard gas line installations and service lateral connections where flexibility and burial depth requirements favor polyethylene over rigid alternatives.

Why Contractors Specify Home-Flex

Contractors specify Home-Flex gas piping products because flexible CSST reduces the number of fittings and connections required to route gas lines through framed walls, floors, and ceilings compared to rigid black iron pipe. Home-Flex CSST is available in 1/2-inch, 3/4-inch, and 1-inch sizes with brass fittings designed and tested specifically for the Home-Flex system, ensuring listing compatibility throughout the installation. Home-Flex Underground pipe meets ASTM D2513 for below-grade gas distribution applications, providing a code-referenced polyethylene option for exterior yard gas lines. The Home-Flex product line covers both interior above-grade CSST and exterior below-grade polyethylene gas pipe from a single brand, giving contractors a consistent system specification for complete gas piping projects.

How to Choose a Home-Flex Product

The most important decision variable when specifying Home-Flex gas piping is the application: interior above-grade distribution or exterior below-grade service.

For interior gas distribution within a residential or light commercial structure, Home-Flex CSST is the appropriate product. CSST simplifies routing through framed walls, floor cavities, and structural elements by eliminating the elbow fittings required by rigid pipe at every direction change. Home-Flex CSST is available in 1/2-inch, 3/4-inch, and 1-inch sizes. Size selection depends on the BTU demand of the connected appliances and the total run length from the meter. The Home-Flex sizing resources at home-flex.com provide flow capacity tables for each tubing size.

For exterior below-grade service lines from the gas utility meter to the structure, Home-Flex Underground MDPE pipe is the appropriate product. Home-Flex Underground meets ASTM D2513 for buried gas distribution. Home-Flex Underground pipe is not approved for above-grade use, inside buildings, or under buildings.

For appliance connections, Home-Flex brass fittings should be used throughout the Home-Flex CSST system to maintain system listing integrity. Local gas codes and the authority having jurisdiction determine what gas piping systems are approved. Confirm approval before installation.
