We have added tube liner to our online shop. This is standard medical grade polythene tubing with an outside diameter of 1.52mm. It can be used to line metal tubes and bottle tubes of appropriate internal diameter. It is similar to Veniard Tube Liner, the tubing used to line Veniard Slipstream copper and aluminium tubes. It is not suitable for lining Needle Tubes. The ends can be easily burred by holding the tube end near (but not in) a lighter flame – avoid setting the tube alight. It is supplied in 2 metre lengths.
