4/6mm Polyurethane CO2 Resistant Tubing - Black

£1.89
4/6mm Black Polyurethane CO2 Resistant Tubing
 

Key Facts

  • 4mm / 6mm dimension (4mm internal / 6mm external).
  • Resistant to CO2 (no leaks).
  • For use in high pressure systems.
  • Bought in 1m increments but will be delivered in one complete length.
 

Description

Regular PVC or Silicon tubing is not resistant to CO2, and over time it will become porous or crack, resulting on loss of gas. You may not even know it's leaking and subsequently waste large amounts of CO2 without realising.

Polyurethane tubing is resistant to CO2 and you can therefore have peace of mind that your pressurised CO2 system will run efficiently for many years to come.

If you require 5 metres, for example, change the quantity to 5 and you will be sent a single 5m length.

Advice: Because Polyurethane tubing is much stronger than conventional PVC or Silicon tubing, it doesn't stretch as much, so to avoid potential damage to your glass or plastic diffusers/bubble counter when connecting it, it is advisable to dip the end of the tubing in freshly boiled water for a couple of seconds to soften it.

This is top quality tubing, but difficult to run around tight bends, because it is so stiff. This is top quality tubing, but difficult to run around tight bends, because it is so stiff.

Not much to say its just CO2 resistant tubing. Gave five stars because as usaual it was an easy transaction with quick delivery. Hassle free with good comms if you need it. Personally I wish they would extend their range...dry ferts, substrate, live plants, all the stuff we use. When you find a good outlet its would be nice to get everything you want from there.

No complaints it does what it is meant to do. Needed a lot of softening in hot water to get over my connector, however, that was my size issue. No complaints it does what it is meant to do. Needed a lot of softening in hot water to get over my connector, however, that was my size issue.
