Coupling can be shut-off => Safe coupling without complications Thread manufactured without seam according to DIN, USAS or JIS => Various connection options Nominal diameters up to DN 10/12 => High KV value, good flow rate Spring made of PEEK or stainless steel, Housing made of PVDF => High media resistance Nipple can be shut-off => Safe coupling without problems The connection principle used in the Series 3K is designed to enable supply lines to be connected and disconnected quickly and frequently. There is usually a risk of aggressive gases or liquids escaping during coupling operations. The quick connectors of our Series 3K are safe because a shut-off element seals the line before the coupling is disconnected. To connect or disconnect the coupling, simply actuate the sliding sleeve. Reliable operation is guaranteed by our choice of material: the coupling is made of PVDF and the spring of PEEK, stainless steel or Hastelloy®.
