Gomax – Refrigeration Thermoplastic Hoses



GOMAX® is a brand of Transfer Oil S.p.A.. The Company, founded in 1979, is today one of the major independent thermoplastic hose manufacturer for medium, high and very high pressures. Through a  network made of the most relevant distributors of each industry, Transfer Oil hose products are distributed in 65 different countries.


The GOMAX® products have been expressly designed to substitute the rigid copper tubing when connecting discharge and suction lines, pressure switches, manometers, oil return and oil equalization lines. The use of flexible hoses, not only simplify dramatically the installation operation, but also eliminates the problems caused by the effect of vibrations that is associated with copper tubing, reducing sound levels and vibration transmission significantly and at the same time eliminating the risk of rupture and leak of refrigerant.



Quadra system


The Quadra system – comprising of thermoplastic flexible capillary hose, fittings in brass and steel and dedicated tooling – gives quick production, in a few simple steps, with superior quality connections to the  pressure test points, gauges, the pressure switches including the oil return circuits and oil level equalization, for air conditioning and refrigeration units of each type and size.
