This CO2 resistant tubing is designed to efficiently carry carbon dioxide with virtually no losses. The material properties of polyurethane tubing allows it to withstand high pressures. Normal airline tubing will harden and crack over time. There will be CO2 losses through normal tubing wall due to its permeability to carbon dioxide.
Use hot water to soften the end of the tubing before connecting to the device e.g. diffuser, regulator, check-valve, bubble counter.
Each quantity is 1m.
