Technical Details


Manufactured from high quality, low density polythene, this tube solution is a popular choice for transporting and conveying air and liquid.

As this polythene tube doesn't rely on plasticiser for flexibility, the chance of chemicals leaching into products is reduced, making it a safe and completely approved tube for food conveyance.

Depending on the intended usage, we can manufacture this tube solution from medium density polythene, high density polythene, ethylene vinyl acetate, and polypropylene for various strength and durability requirements.

  • Highly flexible.
  • Customisable tube solution.
  • Suitable for food and drink distribution.
  • Suitable for low pressure applications.
  • No plasticiser used.
  • REACH, RoHS and BSI ISO 9001 compliant.

Technical Details

Working pressures are based on the short term burst pressure calculated at 20°C using a 4:1 safety factor.

Low density polythene can be used at temperatures up to 55°C, however at lower temperatures the tube will become less flexible.
