Silicone-Free: LABS-free, making it suitable for sensitive environments
Applications: Bulkhead and deck passing for marine, industrial, drinking water, and sprinkler systems
Connection Technology: Press-fitting system with indicator rings for easy identification and reliable installation.
Description
The Geberit Mapress Stainless Steel Bulkhead and Deck Passing is a specialised fitting designed to provide a secure and durable connection for pipes passing through walls, bulkheads, and decks in piping systems. Ideal for environments that demand high corrosion resistance, it is particularly suitable for use in marine, industrial, and other harsh environments where hygiene, pressure, and temperature resistance are critical. This fitting ensures a reliable seal while protecting pipes from external elements, making it a top choice for both concealed and exposed installations.
Key Features
High Molybdenum Content: Manufactured from CrNiMo steel 1.4401 (EN 10088), with a minimum molybdenum content of 2.3%, offering superior corrosion resistance and durability, even in harsh and aggressive environments.
Silicone-Free (LABS-Free): The fitting is silicone-free, making it ideal for environments where contamination from silicone could be problematic, such as in paint shops or sensitive industrial applications.
Protective Tube for Welding: The bulkhead and deck passing comes with a protective tube that allows for safe and efficient welding, protecting the pipe and maintaining the integrity of the system.
Coated Protective Tube: The protective tube is made of steel 1.0039 and coated for additional durability and protection against external elements, ensuring a long-lasting installation.
Hygienic Design: Suitable for installations that require stringent hygiene, such as drinking water systems and other sensitive areas, ensuring the system remains clean and safe.
Versatile Applications: Approved for use in 'wet', 'wet/dry', and 'dry' sprinkler systems, this bulkhead fitting is also suitable for use in a wide range of piping systems, from residential to industrial applications.
Quick and Safe Installation: Utilises the Geberit press-fitting technology, enabling quick, reliable connections without the need for welding or soldering, which reduces labour time and costs.
