Nederman M40-38P Male coupling Ø 40 mm for hose Ø 38 mm

The hose coupler system is available in a wide range to suit most hose diameters commonly used. The couplers are made from electrically conductive plastic material and are available in two diameters of the tapered coupler section 40 and 50 mm. Using the couplers makes it very easy to connect/disconnect the vacuum hose simply by turning-pushing or turning-pulling. 50 mm couplings fit directly into the flap valve KV50 and automatic valve TAV50. To connect 40 mm couplers to either 50 mm couplers or to the above mentioned valves an adapter is used.
