Parflex 518D Non-Conductive Hose

Parflex 518D non-conductive thermoplastic hose was developed to handle 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 can move through hoses over time (permeation). The core material in 518D is highly resistive to the permeation of these fluids. In addition, Parflex gave the 518D-4 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 518C hose.

Parflex 518D hose uses the same fitting and crimp diameters as our current 518C product for a quick and easy replacement.

Designed specifically for the rigors of the aerial lift market including the highest level of non-conductivity, abrasion and permeation resistance.

Product Features:

Twin or multi-line constructions available
Super high density braid for maximum impulse life without loss of flexibility
