Transfer Oil's Twin Hose solutions are the result of joining two or more hoses by means of a procedure that is unique in the industry and that does not compromise hose integrity. The joining process can connect hoses of the same size and specification or different hose types and sizes, as well as electrical cables and wires. The use of Twin Hoses simplifies application requirements, including fluid flow and connections to hydraulic and electric supply. These thermoplastic hoses are supplied in coils by Transfer Oil. An additional operation is required for assembly involving splitting the twin hose. Proper separation instructions are contained within the "Thermoplastic Hose Installation Factors" section.

Transfer Oil also offers custom Twin Hose solutions, including personalized combinations of different hose types or diameters, and the possibility to join hoses with electrical and optical cables.
