Mixed metal supply systems, when lead piping is connected to two other different metallic materials at both ends, usually steel and copper, can result in galvanic corrosion and poisoning of the water supply. In 2015, a lead contamination scare that occurred in Hong Kong .  Following the scare, water industry experts highlighted that plumbing material control and commissioning requirements for new plumbing installations remain a crucial component ensuring the safety of water supply systems in the territory. As a result, each component must undergo strict testing to provide clean and safe building water.

In 2020, Geberit Group – the European market leader in sanitary products, announces that Geberit Mapress Stainless Steel supply system is approved for use in Hong Kong. The stainless steel, non-soldered alternative is widely used in Asia as a safer, more durable alternative and replacement to lead piping and remove the risks of mixed metal supply systems.

Geberit Mapress Stainless Steel is a highly effective supply system and can be used for diverse mediums. Geberit places the highest requirements during manufacture. The high molybdenum content, as an example, ensures a particularly high corrosion resistance. The result is plain to see – a billion times over.

Geberit Mapress Stainless Steel applications

• Potable water
• Heating
• Gas
• Sprinklers
• Industry
• Treated water
• Cooling
• Compressed air
• Gaseous media
• Vacuum

High material and system safety

The optimum composition of the alloy components results in a high degree of material and system safety. Our extensive works standard, which goes beyond the required standards, is the reason for this safety: the Geberit Mapress Stainless Steel system pipes and fittings have a molybdenum content of at least 2.3%.

Simple connection

The defined jaw guide on the Geberit Mapress Stainless Steel fitting ensures that the pressing jaw is positioned in exactly the right position. It also prevents any risk of the joint slipping or being pressed in the wrong place. This prevents failed pressing sequences and ensures reliable and durable connections.

Fast visual check

The blue colour of the pressing indicator on the fitting enables clear identification of the material. In addition, a print on the pipe end facilitates the identification of the dimensioning. The pressing indicator can be simply removed manually after the correct pressing operation.

Compact design

Thanks to the compact geometry of the Geberit Mapress Stainless Steel fittings, they require less space and therefore tighter fitting combinations are possible. Furthermore, Geberit offers numerous fittings that are coordinated with a wide range of applications.

High mechanical strength

The coordinated components lend the system a high load bearing capacity. Operating pressures of 2.5 MPa (25 bar) and more are possible. Due to the high level of mechanical strength, a wide range of applications is possible which extends far beyond the usual domestic installations.

Perfectly smooth

The extremely smooth surface is a prerequisite for added system safety and long-term tightness. The weld seams are smoothed by a mechanical finishing treatment for optimum flow behaviour and a perfectly positioned seal ring. The roughness values are therefore well below the limits set out in standards and guarantee the tightness of the system.

For permanent fixture and a high level of safety

During the pressing procedure, the seal ring is given a pre-defined shape by the pressing jaw of the Geberit Mapress pressing tools. During this process the ring absorbs additional energy for permanent and reliable tightness.

Press, Don’t Stress

Thanks to the pressing technology, installations can be carried out reliably and quickly without complex welding and soldering.

In addition to the standard Geberit Mapress Stainless Steel product range, LABS free fittings are also available.

The billionth Mapress fitting was manufactured in Langenfeld, Germany  in April 2018. This is proof of the success of this technology, which has been standard in almost all sanitary installations for generations. The reasons for this are obvious: reliability, efficiency and safety.
