Up to bolt size M22, the plate pack screw connection on ARPEX couplings is in the form of a close-fitting bolt connection. After that the patented 1) conical screw connection is used. The decisive advantage of this screw connection is considerably simplified fitting. The use of an hydraulic fitting tool is no longer necessary. All sizes can be fitted with a torque wrench. A further feature of the conical screw connection is the genuine positive connection resulting in high centering accuracy and, thus, a high balancing quality. Material: High-grade quenched and tempered steel.
