Corrosion Resistance: High resistance to corrosion due to its molybdenum content, providing long-term durability in aggressive environments.
Description
The Geberit Mapress Stainless Steel Axial Expansion Fitting is designed to accommodate thermal expansion and contraction in stainless steel piping systems. Its robust construction with a bellows made from stainless steel allows for axial movement, ensuring that piping remains secure and flexible, even under conditions of extreme temperature fluctuations. This fitting is ideal for industrial and commercial applications where high-pressure, high-temperature, or aggressive fluid systems are involved. It is particularly useful in systems where temperature changes can cause stress on pipes, such as heating and cooling circuits, industrial water systems, and chemical installations.
Key Features
High Molybdenum Content: With a minimum molybdenum content of 2.3%, the Geberit Mapress Stainless Steel system offers superior corrosion resistance and excellent hygiene properties, exceeding standard industry levels.
Hygienic and Safe: The system allows for thermal and chemical disinfection, ideal for situations where hygiene is paramount. Pre-fitted leakproof plugs protect pressing sockets from dust and dirt during installation.
Versatile Applications: Approved for use in demanding environments, including drinking water systems, industrial applications, and fire protection systems.
Quick and Simple Installation: The pressing technology ensures quick and easy assembly, reducing labour costs and the need for consumables like oxygen or gas. The use of indicator rings and plugs makes it easy to distinguish between different materials and systems.
Comprehensive System: With around 500 fittings and adaptors, it offers flexibility and compatibility with other Geberit systems, including the MasterFix adaptor for fast, tool-free connections.
