the company

WALTHER-PRÄZISION, founded in 1931 as a machine factory, has been developing and manufacturing mono and multi-couplings as well as docking systems since 1951. They are used wherever liquids, steam, gases, electrical and optical signals as well as power current have to be transmitted, connected and disconnected safely.

the company

WALTHER-PRÄZISION engineers develop environmentally friendly solutions which meet the most challenging demands, proving their capability in adverse conditions in industries such as the automotive, aerospace, aviation, chemical, pharmaceutical, offshore, medical, transportation, machine and systems engineering or defence.

Our extensive range allows us to offer the world’s largest programme of mono-couplings, multi-couplings and docking systems, with more than 400,000 variations. Nearly every application can be fulfilled by our standard programme. For special applications we offer individual custom-made designs.

Our quick coupling systems for automation offer pioneering technology, safety, and flexibility and allow efficient use of tools and components.


Sustainability is a longterm strategic success factor not only for WALTHER-PRÄZISION, but also for the suppliers. Passion, respect, integrity and discipline are the corporate values of WALTHER-PRÄZISION. By living these values within the company and also in our external relationships, we want to create a culture of excellence.

HSE Policy

WALTHER-PRÄZISION aims to maintain a safe and healthy work environment for all employees and, at the same time, guarantee the safety and protection of company assets. Furthermore, WALTHER-PRÄZISION implements a high level of general standards of conduct whose compliance is achieved by consistently implementing health and safety measures.


The WALTHER-PRÄZISION brand originated in the 1950s from the requirement of the company founder Carl Kurt Walther to be able to connect and disconnect the supply lines of the company’s own production facilities and its own machine program of Maschinenfabrik Carl Kurt Walther, Wuppertal (founded in 1931) quickly and conveniently.

Convinced of the technical and economic advantages of the product, the first range of couplings was launched on the German market in 1951. Even back in those days, the couplings already satisfied the very highest quality requirements with many of these first generation products still working perfectly today.

Since those early days WALTHER-PRÄZISION has been recognised as an international problem solver and specialist for quick coupling systems, operating worldwide.

The basis of WALTHER-PRÄZISION`s success is innovative leadership, with a clear insight into customer-oriented solutions, combined with first class quality and due consideration for the environment resulting in first class products. WALTHER-PRÄZISION does not mass produce goods! Whether it is milled, turned, welded, glued, cast, injection moulded, punched, pressed or shaped, each item is checked. All assembled couplings, whether standard or special, undergo final function and leak testing before leaving the factory.

All employees at WALTHER-PRÄZISION act according to the motto: expertise through training, experience and curiosity! Precision and responsibility create quality! Quality in particular reduces the customer‘s operating costs!

WALTHER-PRÄZISION will continue to stand for customer service, innovation and highest quality. This is the only way for us to continue to manufacture technically and economically superior products which also benefit the environment.

We would like to thank our many thousands of customers and assure them that also in the future we intend to make every effort to justify the trust they place in and their loyalty to WALTHER-PRÄZISION. We ask everyone else to put us to the test, so that in future, theyalso can become one of our good connections.

Our Know-how


What can we do for you?

Would you like a confidential project discussion on site or detailed information? A phone call or simply an e-mail is all it takes.

research / development


We invest a large part of our development capacity in application-specific projects. We work closely with our customers to develop new, tailor-made solutions.

To this end, we use state-of-the-art tools such as 3D CAD software for efficient design. Advanced software tools allow for simulation of flow behavior, effects of dynamic loads or movement patterns of automated coupling systems to mention but a few, thereby creating the prerequisites for developing quick couplings which are ideally suited for their specific use.

responsibility and Care


Production of the coupling components requires the highest precision. We use modern machining centres and latest production technology to provide for flexibility and accuracy when machining a wide range of materials.

The nearby assembly plant offers both highly automated assembly lines for large volume production of standard couplings and special assembly areas for small batches. In this way, even small batches can be produced economically and to the same high standards.

Our quality management system has been certified to DIN EN ISO 9001 since 1992 and is something that we at WALTHER-PRÄZISION consider a natural component of our top-rate quality standards. Our medical technology production line fulfils DIN EN ISO 13485. Every coupling produced by WALTHER-PRÄZISION undergoes function and leak tests before leaving the factory. Special test facilities are available for extreme operating conditions.



Carl Kurt Walther founds the company in Wuppertal with the WALTHER-TROWAL division. It focuses on the manufacture and sale of machinery, systems and processes for surface finishing through vibration or slide grinding, which has become known globally as Trowalizing (TROWAL® = TROmmel WALther).


WALTHER-PRÄZISION was founded during the 50s to meet the demands made by the company founder for a quick connector for the connection and disconnection of supply lines for a range of production machines manufactured by his company Carl Kurt Walther, Wuppertal. Convinced of the technical and economic advantages, the first range of couplings was launched on the German market in 1951. Even back in those days, the couplings already satisfied the very highest quality requirements with many of these “first generation” products still working perfectly today.
