Hydraulic catalogue - Normapress

IntroductionSelect the coupling adapted to your installationThe optimum efficiency of a hydraulic system depends, most importantly, on the choice of a connection system perfectlyadapted to each installation. The principal criteria to consider are:Connection technologyTwo connection technologies are featured in this catalogue:● cutting ring couplings to DIN 2353/ISO 8434-1Their characteristics and solutions diversity make these couplings suitablefor all applications.- flexible assembly: use of a pre-assembly machine, standard manufacturing processor direct manual assembly, for individual assembly or maintenance.- adaptor solutions to ISO 8434-1 / ISO 8434-2, to go directly from cutting ring technologyto 37° flare couplings.- weld nipples, for severe conditions of use (whip-lash, excessive vibrations…)and particularly high nominal pressures3 types of cutting ring depending on the installation :12-DiNova ring:durable sealing, thanks to three gripping bites and two seals; safety installationsthanks to a controlled mechanical stop; resistance to aggressive fluids and hightemperatures ensured by PTFE seal material (PTFE).-double-bite ring: for all standard applications.ease and safety of assembly, as well as excellent sealing performances.-single bite ring: for all applications under 100 bar.for use with the series LL (limited tightening torques).● 37° flare couplings to ISO 8434-2This coupling range is suited to many applications. Its principal specifications:- metal/metal sealing, enabling use with many fluids and at very high temperatures.- maximum tube gripping and safety, due to the 37° flare.- assembly ease, and low tightening torques- adapted to metric and inch tubes.
