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.
