Hi! Thank you for your query about the Chicago Fittings XR-21J-16-36-ZDC flexible riser. No, while the riser's flexible conduit is buried along with the PE gas pipe, the critical connection points—the joints—are intended to remain above ground. This design approach minimizes the risks associated with underground joints, such as undetected leaks or corrosion. Therefore, while the flexible portion of the riser is buried, the actual fittings and connections should be installed above ground to comply with safety standards and best practices. Once you are ready to order this flexible gas riser, just click on the "Add to Cart" button, fill in the information needed, and we'll take care of the rest. Thank you for trusting PlumbersStock. Have a great day!
