Poppe + Potthoff is a partner of global OEMs and Tier 1 suppliers in various technically demanding industries such as automotive, heavy duty, mechanical engineering, marine or aerospace. Our solutions enable the highest safety and reliability through absolute precision. Founded in 1928 in Werther, Germany, we have grown into an international group with over 1,600 employees at 18 locations. Our products range from specially developed common rail subsystems, high-pressure lines, precision and industrial couplings to sophisticated hydrogen supply systems and components for e-mobility applications. For hydrogen supply systems, we take a holistic approach, designing all the key components required for H2 routing from the tank to the fuel cell or hydrogen combustion engine. In particular, this includes on-tank valves, H2 rails, TPRDs, HPRVs and lines. Our portfolio is rounded off by the development of test systems for digital 100% end-of-line testing in production. Our self-designed test benches are used for a constant alignment of manufacturing processes and quality standards.
