Product information

Hose Construction

The cargo hoses are constructed from polypropylene, PTFE and/or ECTFE films and fabrics, depending on the application and an outer cover of PVC coated nylon fabric. This cover is abrasion, weather and ozon resistant. For more demanding applications hoses with tubes are also available.
The cryogenic hoses are constructed from polyamide or polyester films and fabrics and an outer cover of polyamide. On request hoses with rope lagging can also be produced.

Internal and external wires

A choice can be made between galvanized steel, polypropylene coated steel and stainless steel in 316 and 304 for the internal wire, depending on the application. External wires can be galvanized steel and stainless steel in 316 and 304, depending on the application.

Assembling

The assembly of the great variety of End Fittings take place by means of a two component epoxy and swaging the ferule onto the hose, so called wet method.

Electrical Continuity

A dual connection between the internal and external wires and end fittings guarantees electrical continuity.
