Sonda high temperature hoses are constructed from multi-layers of thermoplastic films which form a sealing and permeation barrier, supported by fabric layers for mechanical strength. The hose layers are held and tensioned by internal and external steel wire helices.  All hoses get the approval of international standards including EN13765, BS 3492(1987)AX + BX and BS5842(1980) and can be supplied with external swaged and factory-fitted end connections to the customers’ requirements.
