Easy identification of different media circuits

The ESMK DN 5 and ESIFK DN 7.8 series are part of Lüdecke’s Safeconnect line. The ESMK and ESIFK ensure easy identification of different media circuits and have been developed to prevent incorrect connections between different media. This is achieved by using coloured anodised, knurled aluminium sleeves on the coupling and coloured anodised aluminium rings on the plug. Each colour coding is combined with a unique shape coding, ensuring that mismatching connections are impossible.

The ESMK DN 5 series is available in both single and double shut-off versions. The ESIFK DN 7.8 series is only available in a single shut-off version.
