Chicago Fittings, that Natural Gas and Propane Gas systems should have as few joints as possible, and more importantly, those joints should be located above ground wherever possible. The X-Riser® with an integral service head adapter accomplishes both of these criteria. The use of an X-Riser® removes a minimum of two (2) below grade joints per riser when compared to that of a standard pigtail style anodeless riser. In addition, those joints, buried below ground are now moved to a single above grade joint eliminating the risks and liabilities associated with below grade joints. with the use of the X-Riser® system, gas is distributed from main to meter, meter to appliance, or propane tank to house with a solid (jointless) underground pipe. Combining this philosophy with the long list of features & benefits of the Sealastic™ sealing technology makes the X-Riser® the most reliable, safest and most cost effective method for gas piping systems.
