Description
Composite hose made from polypropylene fabrics and films with an abrasion resistant PVC coated fabric cover, reinforced with internal and external wire helixes
Principal Applications
Transchem is suitable for the transfer of acids and alkalines. Transchem-S has the added suitability for applications involving corrosive atmospheres and splash.
Note: Electrical continuity can be maintained for this hose by baring the inner wire (i.e. removing the polypropylene coating) near the fitting to allow positive connection of the wire to the fitting. This process however may introduce a potential corrosion path to the inner wire so care needs to be taken.
