• Eliminate below grade joints at the building
• Bottoming nut (positive stop) eliminates the need for torque measurement
• 1-piece bi-directional seal/ferrule assembly design eliminates worries of ''order and orientation'' of multiple internal components
• Swage collar design eliminates the need for a weep hole which exposes the PE to both UV-rays and outdoor elements
• Eliminates the need for chamfering tools and fusion equipment
• No chamfering - a simple clean cut is all that is required
• Bi-directional seal assembly can't be installed improperly where some competitors multiple internal components must have proper order and orientation to function properly
• No torque requirements - all X-risers incorporate the "bottoming" or "positive stop" design, simply tighten the compression nut until it is metal-to-metal and you are done
• Simple designs can be installed with 1-flat jaw wrench extending the life of protective coatings commonly flawed or removed by pipe wrenches
• Integral barbed stiffeners are permanent (not loose) for additional pull-out resistance
• Quality - Chicago Fittings products are CNC machined from solid bar stock (not castings) providing high quality product with the most precise threads and design flexibility

Applications: For natural gas applications
