Our DNV-GL PTFE flexibile hose range

The Kongsberg Automotive DNV GL, PTFE Flexible hose range is a flame resistant, convoluted multilayer hose with bonded fibreglass and Stainless-Steel wire braid reinforcement cover for use on demanding marine and offshore applications.
The convoluted profile ensures easier crimping of the hose and with the approved DNV GL fitting and ferrule range now offers a proven minimum 150K impulse cycle life expectancy at elevated temperatures. The new convoluted profile offers improved vacuum resistance where negative pressures may be detrimental to the life cycle of the hose assembly. The helically convoluted design allows for easier draining when compared to other non-PTFE hose types whilst also giving a smaller bending radius allowing the fitment of the product in tighter confines.
