Electrofusion fitting (electro-muff) HDPE 75, black color (HDPE drainage) 365.771.16.1

Highly durable and tight connections in the Geberit HDPE drainage system.

HDPE electrofusion socket 75 is a key element of the Geberit HDPE drainage system, designed for connecting pipes with a diameter of 75 mm. Made of high-quality polyethylene (PE-80), it ensures reliability and long-lasting tightness in various applications – from draining water from buildings, through roof drainage, to industrial installations. The socket is ideal for gravity and vacuum systems, as well as for laying in concrete.

The electrofusion socket allows for making connections by electrofusion welding, which guarantees durability and resistance to external factors. PE-80 material is characterized by high chemical resistance – it withstands contact with most standard alkalis, acids and chemicals (about 95%), making it an excellent choice for installations exposed to an aggressive environment. Additionally, polyethylene is resistant to UV radiation, which allows for storing pipes and fittings outdoors for a longer time.

Application and benefits for professionals:

• Versatility: The socket is suitable for various types of installations – from domestic sewage drainage to industrial systems.
• Connection durability: Electrofusion welding ensures a tight and durable connection, minimizing the risk of leaks.
• Chemical resistance: PE-80 material guarantees resistance to a wide range of chemicals, which increases the lifespan of the installation.
• Easy installation: Combined with appropriate electrofusion welding machines, socket installation is quick and efficient.
• Possibility of laying in concrete: The Geberit HDPE system is adapted for direct embedding in concrete, which increases its stability and protection.

Construction features and parameters:

The socket is characterized by a simple construction and precise dimensional fit – the outer diameter of the connection pipe is 75 mm, and the working length of the connection is 1.5 mm. Made of raw polyethylene (both inner and outer surface) ensures optimal surface for electrofusion welding. Black color facilitates identification in the drainage system. The nominal connection diameter is DN 70. The length of the socket itself is 60 mm, which provides an adequate contact surface during welding. It is important to use dedicated electrofusion welding machines and follow the manufacturer's instructions to obtain optimal connection durability.
