Geberit Mapress Carbon Steel

The first choice for closed circuits

The economical alternative

Geberit Mapress Carbon Steel was designed for installations in which economy is of the highest priority. The Geberit Mapress Carbon Steel system pipes are available in two designs – with a cream plastic jacketing made of PP or with an outside zinc plating. System pipes with both inside and outside zinc plating are also available for special applications.

Geberit Mapress Carbon Steel applications

  • Heating
  • Sprinklers
  • Industry
  • Cooling
  • Compressed air
  • Gaseous media

Many good reasons for Geberit Mapress Carbon Steel

For permanent fixture and a high level of safety

The Geberit Mapress seal ring is given a pre-defined shape during the pressing procedure. During this process the ring absorbs additional energy for permanent and reliable tightness.

Red pressing indicator

Fast visual check

The red 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 dimension used. The pressing indicator can be simply removed manually after the correct pressing operation.

The guide contour of the pressing jaw ensures a reliable pressing operation of Mapress C-Steel

Simple connection

Pressing jaw guide for safety

The defined jaw guide on the Geberit Mapress Carbon 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.

Homogenous material structure after the pressing operation

Homogeneous material structure

Thermally perfect weld seam execution

Particularly in the seal ring contact surface area, the clean weld seam contributes significantly to ensuring the system's permanent tightness and to cutting susceptibility to corrosion. The weld seam processing has to meet Geberit's stringent quality demands. A special thermal treatment ensures the desired homogenous material structure and thereby an optimum pressing operation.

Additional safety

Unpressed Geberit Mapress Carbon Steel fitting detection

The Geberit Mapress seal ring provides the pressing indicator with additional safety. Due to its special contours, unpressed connections leak during the pressure test. This recognition feature prevents harm later during operation.

Protection plug

Protection against dust and dirt

The pressing sockets of Geberit Mapress Carbon Steel sockets are sealed with a plug that protects the supply network from dust and dirt. The colour of the protection plug also identifies the application.

Mechanical strength

Wide range of applications

The coordinated components lend the system a very 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 heating installations.

A Geberit Mapress Carbon Steel system pipe is successfully pressed

Faster connection

Pressing instead of welding or soldering

Pressing is not only straightforward, but also fast – in fact, it's around twice as fast as welding or soldering. The pressing procedure itself is fast and simple: cut to length, deburr, mount the fitting, press – and you’re done.

Various materials and coatings for Geberit Mapress Carbon Steel

Geberit Mapress Carbon Steel system pipes

Coating for corrosion protection

The plastic coating made of polypropylene reliably protects Geberit Mapress Carbon Steel system pipes in the dimensions DN 12 – DN 54 mm against external corrosion. All Geberit Mapress Carbon Steel system pipes from DN 12 to DN 108 mm are also available in a zinc-plated version for individual solutions for renovations and new constructions as well as for surface-mounted and concealed installations.

Soldering or welding the pipe joints of Mapress Carbon Steel

No open flames

No risk of fire

The strength and tightness of the press connection is achieved by cold deformation of the pipe and fitting. In contrast to welding and soldering operations, no open flame or heat is required. Additional protection measures are unnecessary for renovation and repair work.
