A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allowing high-pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various applications. This product is made for the 6kg meko. The main advantage is that the gadget allows you to convert the meko gas into a countertop (table cooker). It is designed for Butane, Propane, or any mix.
