The safe connection for all industries
Hose fittings as per EN 14420 are considered a safe and high-quality connection between the hose and the plant within the given pressure and temperature ranges (for higher pressures and temperatures integration as per EN 14423 is available). They can be used in almost all industrial areas; they are particularly suitable for applications with media hazardous to humans (occupational safety) and the environment (environmental protection).
Hose fittings as per EN 14420 – also called flanged hose fittings – consist of a connector with a safety collar and a set of clamp fittings with safety collar. The connector is inserted into the hose and carries the respective selected connecting end. The hose is then pressed onto the connector from the outside by means of the clamp fittings. The clamp fittings are equipped with threaded ferrules on their inside, to which the hose will attach when properly assembled. After proper assembly, the safety collar of the clamp fitting inserts into the safety groove of the safety clamp thus safely holding the hose on the connector.
Screw-on clamp fittings offer the advantage that they can accommodate hose tolerances and different hose dimensions. In this context, the clamping area of the clamp fitting must be carefully checked prior to use. Clamp fittings can be re-tightened and re-used at any time.
