Non-Conductive Thermoplastic Hose


In response to customer demand, Parflex engineers have developed 518D non-conductive thermoplastic hose to withstand the harshest environments, both internally and externally.   The 518D hose, from Parker Hannifin, has a new core material that is more resistant to permeation and an outer jacket that has greater abrasion resistance than many other products on the market today.   

Many end users are using hydraulic fluids with aggressive additives that move through the hose over time (permeation).  The core material in 518D is highly resistive to the permeation of these fluids.  In addition, Parflex gave the 518D a special reinforcement package to reduce the reinforcement diameter, allowing for an increase in the thickness of the special PFX cover.  In lab studies, this improvement has shown to provide as much as 5x more abrasion resistance than the current thermoplastic hoses used in this application. 

Available in sizes 1/8”, 3/16” and 1/4".
