Double-layer HDPE Electrofusion fittings are primarily used in underground fuel station piping systems. They are designed to handle fuel transfer operations safely and efficiently, with a primary pressure rating of 10 bar (145 psi) and a temperature range of -40°C to 50°C. 

Double-layer HDPE Electrofusion fittings  utilize an advanced electrofusion welding process, which allows for easy and secure connections. The welding unit automatically calculates the necessary settings, ensuring a leak-proof connection regardless of the pipe diameter or ambient temperature.
