Couplings
Tight connections for tunnelling and sewer construction
Whether you need stainless steel drive couplings with rubber seals, variants with sealing rings or plastic couplings with corresponding sealing rings, Infrastep offers solutions that seal reliably, are easy to install and can be flexibly adapted to your project.
Propulsion couplings
with integrated rubber seal
The stainless steel coupling with integrated rubber seal ensures a permanently tight connection during tunnelling work. It is resistant to high loads and is easy to install.
Propulsion couplings
with sealing ring
This thrust coupling is supplied with a separate sealing ring and ensures reliable and permanent sealing during pipe jacking. They are available for various pipe dimensions and are characterised by their robust construction, which guarantees a secure connection even under high loads.
Plastic couplings
We manufacture plastic couplings using injection moulding. Different materials and matching seals ensure that you always get the right solution for your project.
Advantages of the materials at a glance
Stainless steel couplings made of V4A (1.4571) are the right choice when maximum load-bearing capacity and durability are required. They are permanently resistant to corrosion, can withstand high pressure and ensure reliable connections even in aggressive environments. This makes them particularly suitable for new construction projects and demanding tunnelling work where nothing can be left to chance.
Plastic couplings made of polypropylene (PP), polystyrene (PS) or acrylonitrile butadiene styrene (ABS) score points for their low weight and ease of handling. They can be customised using injection moulding, making them ideal for renovations or special structures. At the same time, they offer good resistance to many chemical influences and provide a cost-effective alternative for projects where flexibility and economy are paramount.
