Luxfer’s LCX-XD™ (Extreme Duty) cylinders are uniquely designed for the most demanding situations and first response units requiring more ruggedly designed cylinders. XD cylinders were designed and developed in consideration and consultation with PDs carrying out operations within close quarter urban environments, such as fire escapes and underground transit systems. Through Luxfer’s proprietary manufacturing process, XD cylinders feature reinforced dome and valve ends shown to provide three times (3X) the abrasion and damage resistance of standard Luxfer LCX™ cylinders and available competing products.
