Permasert XL plastic couplings will save you time and money on gas main repairs, extensions and tie-ins. Whether you prefer bolt-on metallic couplings or electrofusion fittings as your primary method for joining gas mains.

Bolt-on Metallic Couplings
Bolt-on metallic body couplings require cathodic protection in order to meet DOT regulations. When comparing material costs, include the stiffeners, anode, wax tape and tar required to install a metallic coupling. Permasert XL is shipped ready to go in the ground. Permasert XL couplings also provide significant labor savings compared to metallic couplings when considering the time to completely install the fitting, anode and apply protective coatings. In addition, there is no future cost for anodic cell monitoring and maintenance.

Electrofusion
Electrofusion, when used for main repairs, extensions and tie-ins has numerous drawbacks compared to Permasert XL. Electrofusion requires more installation time for surface preparation, dealing with misaligned pipe and fusion cool time. There are additional costs for the larger ditch size and resulting increased excavation and restoration, as well as lost time sheltering the fusion process in poor weather conditions. If transitioning from steel or cast iron to PE, a transition fitting is required as well as a fusion fitting. Further savings are realized from the reduced labor and overtime wages often associated with emergency repairs. The bottom line is Permasert XL will deliver measurable savings to all utilities, even those committed to electrofusion.
