Precision steel tubes
Your customer's request is our aspiration. Poppe + Potthoff are “The precision-makers”. We deliver customised solutions such as precision steel tubes, for example, in small batch sizes or large-scale production. Whether round, profiled, ring, capillary, chain tube or injection lines, products from Poppe + Potthoff enable demanding and top-quality solutions for each field of application.


Common rail / lines
Are you looking for a reliable partner for high-pressure lines and precision components such as injector bodies and pressure pipe nozzles? Poppe + Potthoff supplies 100% precision and quality for very powerful diesel engines in the passenger car and commercial vehicle sector as well as for common rail subsystems.


Precision components
For more than 30 years, our customers have come from the automotive area and other branches of industry in which precision components are required for a variety of applications. Poppe + Potthoff precision components are used in the systems of passenger and commercial vehicles. This includes brake and injection systems, vehicle safety, hydraulics, transmission, steering and much more.


R+W belongs to the Poppe + Potthoff group of companies so that we are able to offer our customers complete solutions. That way we are leading in wear- and maintenance-free couplings with a very long service life. R+W precision and heavy-duty couplings provide maximum efficiency and process reliability.


Machines / systems
As a specialist for high-pressure technology, we have highly satisfied customers in the automobile, shipping and machine building sectors as well as in fluid and medical technology. Our division, Poppe + Potthoff Maschinenbau, supplies the systems that support the development and efficient production of extremely resilient metal and plastic components.


Railing systems
More than 90 years ago, Poppe + Potthoff started with a tube mill for precision steel tubes. A broad range of products for satisfied customers grew out of this experience. This also includes a plant in the USA for railing systems, which has taken a leading position with more than 2000 installations.


May we be precise for you?

We develop and manufacture highly pressure-resistant common rails and lines as well as precision turned and milled parts for the global vehicle industry.

We also supply numerous other industries with precision steel tubes and couplings for mechanical engineering as well as our test benches and railing systems.


Poppe + Potthoff grows with new challenges

For and with our customers, we develop and manufacture technically sophisticated metal components and systems for specific and innovative applications. With highest precision, we create quality, reliability and safety. This is our promise to our customers and our claim to ourselves.

With courage and openness to technology, we drive innovations forward every day in order to find customized solutions for our customers and improvements from development to series production. This includes precision steel tubes, common rails, precision turned parts and couplings as well as test benches and autofrettage systems developed and manufactured in-house by our mechanical engineering department. We learn from and with each other, make better decisions together and develop in a sustainable way - also with regard to our environment.

In our Technology Centre, we manufacture prototypes specially designed to meet our customers' requirements before they are mass-produced. Our technically sophisticated and absolutely precise solutions are used in the automotive and commercial vehicle sector, the shipbuilding industry, toolmaking and mechanical engineering and other industries. Poppe + Potthoff - We are "The precision makers".
