RS - couplings with threaded ferrules as per EN14424 are used in areas where space is limited. Couplings with threaded ferrules are also used for situations where the operating pressure exceeds 10 bar (connections using hinged bolt clamps are not possible) or where the hose cannot be connected using clamping fitting because of the thickness of the hose wall.
Couplings with threaded ferrules as per EN14424 are hose fittings that consist of a connector and a threaded ferrule. In contrast to all other types of integration, the hose in this integration is pressed from the inside out into the ridged profile of the threaded ferrule. To do this, the threaded ferrule is first pushed over the end of the hose to be assembled and only then is the connector (or swivel) screwed into the threaded ferrule by means of a fine thread. The thread pushes the connector into the hose, which is pressed out against the threaded ferrule as the connector enters the hose. Following assembly, it is essential to check that the hose is correctly seated in the fitting. An inspection hole is provided in the threaded ferrule for this purpose.
