HOME-FLEXTM Underground gas pipe is Medium Density Polyethylene (MDPE) gas pipe. It is also referred to as PE or poly gas pipe. It is made in accordance with the ASTM D2513 standard. It is approved for direct burial into the ground in accordance with the local plumbing code at the installation location. It is flexible, lightweight, easy to work with and easy to install. Unlike metallic gas pipe, it will not rust or corrode when properly installed. HOME-FLEXTM Underground PE gas pipe is iron pipe size (IPS). It is approved for use with Natural Gas or LP gas. It is never to be installed in a building or house. It is never to be installed under a building or house. It is never to be installed above grade.

FAQs
No. Polyethylene gas pipe, no matter who manufactures it, is not to be used in a building or under a foundation with a structure on it. Not only is it against all codes, it is potentially dangerous.
No, all yellow gas pipe needs to be at or below code-mandated burial levels. The yellow poly pipe should never be above grade.
Yes. It is certified for use with Propane as well as Natural Gas.
Yes. Unlike some push-to-connect fitting manufacturers, our underground fittings can be disassembled and reused.
We recommend you check the entire system for 30 minutes at 15 psi. Overnight testing is not recommended due to “false positives” that may result from temperature and barometric changes.
No, they are completely different product lines and are not compatible.
No, the product line is purpose made for direct burial and does not need to be wrapped nor put in a conduit.
No. Unlike some push-to-connect gas fitting manufacturers, our gas pipe does not need to be chamfered prior to installation of its compression-type fittings.
CTS means “copper tubing size” which is significantly different that “IPS” (iron pipe sizing) which is most prevalent in the underground gas category today. So, even though your pipe may say “1/2” CTS” it will not work with ½” IPS pipe fittings.
Yes. We have a ½” IPS to CTS conversion fitting. No other sizes are currently available.
No, the riser may never be altered. The PE end may be cut slightly shorter. We suggest you dig the trench deeper under the riser to adjust your installation level.
Yes, so long as the pipe and fitting sizes are the same. All manufacturers of D2513 poly pipe are held to the same dimensional and material standards.
This means “standard dimension ratio” It is the ratio of a pipe’s average outside diameter to its minimum wall thickness. If adding to an existing underground gas installation, always ensure that dimensions are the same.
Please refer to the Fusion Installation Guide in the Resources section for more details.
No, they are dissimilar materials and cementing/bonding would be an issue. Further, they are not certified for use together.
Please refer to the System Design & Installation Manual in the Resources section for more details.
Absolutely. We have all sizes of transition fittings and meter risers (1/2” through 2”) that will enable you to make that metal-to-poly transition. Further, we recently introduced a new conversion fitting in ½”, ¾” and 1” sizes.
Typically, underground gas systems run at 1/4-10psi and are stepped down to ¼ psi for natural gas and ½ psi for LP gas via a regulator either upon entry to the home or at the individual appliances. Our underground pipe is rated for a maximum of 80 psi and our fittings are rated for a maximum of 125 psi. All spec/submittal sheets are available in the Resources section.
This is a 14-gauge or thicker wire that is installed beside the poly pipe prior to burial. It extends to the surface and is wrapped or zip-tied around the riser. A detection service can connect their equipment to the wire and determine the underground routing of the gas pipe prior to digging.
