Low cost beer and soft drinks dispense tubing …

For many years, polyethylene, commonly referred to as MDP (medium density polythene), has been the most widely used monolayer tubing for dispensing soft drinks and beer. It can be used in pythons, towers and as a gas or keg line.

Valpar Micro Matic manufacture a range of MDP tubings, either natural, tint or solid coloured to suit particular applications, along with Valpar MDP Codemaster, the world’s first beverage tube to have coloured stripes for line identification.

Due to its low cost and good thermal conductivity, polyethylene is also the most commonly used plastic tube for water and glycol recirculation lines in python.


  • Reasonably flexible
  • Good inner surface finish
  • Taint free
  • Moderate gas retention
  • Option of coloured stripes (ask for MDP Codemaster)


  • Low cost solution
  • Ideal for post-mix applications
  • Easy line identification with Valpar MDP Codemaster
  • Compatible with barb and push-in fittings

Polyethylene (MDP) tubing is a low-cost solution particularly suitable to meet the requirements of the soft drinks industry, especially in post-mix applications. Polyethylene is also suitable for beer dispense, although, due to limited resistance against bacteria and yeast growth, weekly cleaning of the lines is usually necessary.

Polyethylene (MDP) is better than EVA or PVC (Vinyl) for beer dispense as it imparts no taint to the beverage.


Valpar Micro Matic Polyethylene tubing (natural, tinted colour and Codemaster) is approved by the German SK Zert Authority for dispensing beer, soft drinks and potable water.

Also approved by the North American National Sanitary Foundation – Standard NSF51
