Copper tube for LPG systems

Copper tube (copper pipe) is traditionally fitted between the tank and the regulator. Copper is known for its durability, hence it became the natural choice when designing the first LPG systems. In Poland, the copper tube in the gas installation is no longer so popular due to the price, but there are countries where only the gas installation must be based on a copper tube - this is a legal requirement. In Poland and other European countries, the copper tube has been successfully replaced by thermoplastic (thermoplastic hose).
