125 flanged cast iron coated with plastic, black color (HDPE sewage system) 368.745.00.1

Cast iron collar for Geberit HDPE sewage systems

This collar, with a nominal diameter of DN 125, is a key element in the construction of durable and reliable Geberit HDPE sewage systems. Designed for both internal installations in buildings and external ones – including underground, in concrete or on bridges – it provides safe and tight connections. Made of cast iron coated with plastic, it combines mechanical strength with corrosion resistance.

This collar finds application in a wide range of installations: from draining water from buildings and roof drainage, to industrial systems and commercial facilities. Its design allows for easy connection with Geberit PE collar sleeves, simplifying installation and ensuring long-term tightness. The collar thickness is 14 mm, and the pressure class is PN 10. The outer diameter of the pipe it is designed for is 125 mm.

Resistance and durability in demanding conditions

The Geberit HDPE system is characterized by exceptional chemical resistance – it withstands the action of approximately 95% of standard alkalis, acids and chemicals. Additionally, the material is resistant to UV radiation, allowing for long-term outdoor storage of elements without loss of properties. This makes Geberit PE collars an ideal solution for installations exposed to difficult environmental conditions. Cast iron coated with plastic provides additional protection against corrosion and mechanical damage, guaranteeing long-term reliability.

Installation and compatibility

Geberit PE collars are designed for easy installation. Specialized machines and tools for butt fusion or electrofusion welding are used to connect them. This makes the installation process quick, precise and guarantees a durable and tight connection. Compatibility with other elements of the Geberit HDPE system provides design flexibility and the ability to create comprehensive sewage solutions tailored to the individual needs of the investment.
