Rubber compensator type 50

Expansion and vibration absorption for pipelines

Data sheet

Product information

The Type 50 rubber compensator from WILLBRANDT is a flat corrugated, highly elastic compensator for compensating for expansion, vibration and noise in piping systems. It is used in building technology, plant engineering, water and wastewater technology, engine and shipbuilding as well as in solar and wind energy systems.
Thanks to its flat corrugated shape, it offers low flow resistance and reduces up to 70 % of the incoming energy.

Special features

  • Highly elastic rubber bellows with carrier inserts and molded sealing bead (self-sealing, no additional seals required)
  • Flange design: flanges made of galvanized steel that can be rotated on both sides (PN10 standard)
  • Large movement absorption in all directions (axial, lateral, angular)
  • Noise attenuation of structure-borne and liquid-borne sound
  • Approvals: CE, drinking water, FDA/BfR compliant, shipbuilding approvals, TÜV tested according to DIN 4809
  • Options: Vacuum support spiral, PTFE lining, bracing, protective covers, potential equalization

Variants & areas of application

  • Type 50 red SP – Heating systems, warm/hot water up to 110 °C
  • Type 50 red – drinking water, cooling water, weak acids/alkalis
  • Type 50 yellow – oils, lubricants, gases, fuels
  • Type 50 white SP – food quality, CIP cleaning up to 130 °C
  • Type 50 green – chemicals, aggressive media
  • Type 50 orange – liquid gas, up to 25 bar
  • Type 50 PTFE – Chemical expansion joint with PTFE lining for high chemical resistance

Advantages for your system

  • Reduces energy losses and vibrations
  • Increases the service life of piping systems
  • Versatile use in industry, shipbuilding, energy systems
  • TÜV-tested, FDA/BfR-compliant for sensitive applications

Valve production and plant engineering – compensators as system components

Compensators are far more than just flexible connecting elements – they are a central component of modern valve and system solutions. In complex piping systems, they take on the task of compensating for expansion, vibrations and pressure fluctuations and thus make a decisive contribution to operational safety, durability and efficiency.
Our compensators are not just standard products, but are used as integrated system components in valve production and plant engineering.

This means for you:

  • Integration in SKID assemblies – for modular and compact system solutions
  • Special versions for high temperature and aggressive media – ideal for power plants, chemical and process industries
  • Combination with heating jacket and insulation – for maximum energy efficiency and safety
  • Plant engineering expertise – we plan and manufacture complete valve stations, pump and compressor systems as well as individual piping assemblies


With this combination, we create customized solutions that not only supply individual components, but also complete systems for your industrial requirements.
