Heavy-duty rubber hose lines "RN-F" have rubber insulating sleeves and are coated with neoprene rubber. They are oil, UV and ozone resistant and are suitable for temperature ranges from -30°C to +60°C. Thanks to their good mechanical resistance, they can withstand high stresses in dry and damp rooms as well as in industrial water and can be used permanently outdoors, e.g. in agricultural operations or on construction sites.
