4x6mm PVC Dosing Tube

4x6mm PVC dosing tube

4x6mm PVC dosing tube is designed for vacuum applications such as the suction side of a dosing pump and can be supplied cut to size from any length up to 100 metres.

4x6mm PVC Dosing Tube.

PVC (PolyVinyl Chloride) dosing tube is available with an internal diameter of 4mm and an external diameter of 6mm for use with chemical dosing pumps such as our AT1 series, AT2 series and AT3 series.

4x6mm PVC is fully transparent, offers good chemical resistance and is designed to be suspended into a chemical container or dosing tank providing a suction route for a chemical dosing tank. We strongly recommend checking the compatibility of your chemical reagent with the PVC dosing tube, using our chemical compatibility checker.
