The patented screw-in-fittings of seawater resistant aluminum with full nominal diameter are flow optimised and fulfil the most stringent requirements for tube holding force in closed coolant circuits with aluminum heat sinks. That is why they ensure a reliable tube connection also in case of tube movement, tensile loads, impacts and vibrations at the machine.
The screw-in fittings of Series 5500 are designed for the fast connection and disconnection of coolant tubes in closed coolant systems with aluminum coolers in industrial applications, welding technology and robot applications. Series 5500 is designed for intuitive operation and disconnection even after extended periods.
