8/12 PVC

8x12mm PVC Dosing Tube

8x12mm PVC dosing tube

8x12mm PVC dosing tube is suitable only 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.

8x12mm PVC Dosing Tube

PVC (PolyVinyl Chloride) dosing tube is available with an internal diameter of 8mm and an external diameter of 12mm, for use with chemical dosing pumps in our AT4 range.

The 8x12mm PVC dosing tube is fully transparent and is designed to be permanently suspended into a chemical container, or chemical dosing tank, to provide the suction point for a chemical dosing pump or a peristaltic pump.  We strongly recommend checking the compatibility of your chemical reagent with the PVC dosing tube, using our chemical compatibility checker.

Technical information for use as a guide only.  Pressure values given are based on the short term burst pressure at 20°C.  Any increase in temperature above 20°C will result in a decline in working pressure values.  We strongly recommend you check our chemical compatibility database and speak to your chemical supplier, to ensure that all materials are compatible with the chemical to be dosed.

8x12mm PVC Dosing Tube Features & Benefits

8x12mm PVC dosing tube is fully transparent, and combines good chemical resistance with a soft material, making it ideal for suction tubing on dosing pumps and is available with lengths up to 100 metres, or cut to size.

Flexible, low cost and with a working temperature suitable for most applications, makes the 8x12mm PVC dosing tube, ideal for most suction applications, when combined with chemical dosing applications, subject to chemical compatibility.  Suitable for use in food & beverage applications, the 8x12mm PVC dosing tube doesn't impart taste or odour into contents.
