What Poppe + Potthoff does

Poppe + Potthoff GmbH is a family-owned German precision engineering company founded in 1928 and headquartered in Werther, Germany, operating in more than 50 countries with over 1,500 employees. The company develops and manufactures high-pressure metal components and systems serving global automotive OEMs and Tier 1 suppliers, with product lines spanning precision steel tubes, common rail high-pressure fuel injection systems (for passenger cars, heavy duty, marine, and gas media applications), precision-turned components for braking, injection, safety, solenoid valve, transmission and steering systems, and couplings via its wholly-owned subsidiary R+W (Antriebselemente GmbH). The machine systems business produces capital-intensive validation equipment including autofrettage systems (up to 16,000 bar for development, 12,000 bar for serial production), burst pressure test systems (up to 15,000 bar), impulse test stands (up to 6,000 bar at 30 Hz), leak test stands, function test stands, pressure generating units, and hose test stands.

The company has repositioned its growth thesis around two emerging platforms: the TOPAQ modular hydrogen supply system (On Tank Valve, Pressure Control Unit, H2 Pipes, High Pressure Regulation Unit, and Thermal Pressure Relief Devices) enabling safe hydrogen transfer from tank to fuel cell or hydrogen engine, and modular test stands for e-mobility that validate thermal management components across -40°C to +140°C and 0.2 to 12 bar for EV batteries, power electronics, cooling circuits, and electric motors. Poppe + Potthoff operates a Tier 1 direct enterprise sales model with custom pricing through multi-year contracts and engineering co-development, distributing through wholly-owned subsidiaries and long-term partners. Recent strategic activity includes full membership in the Clean Energy Partnership (February 2026) and repeat recognition in the TOP 100 innovation competition (2023, 2025).

Core offering

Poppe + Potthoff develops and manufactures precision-engineered metal components and systems, including common rail high-pressure fuel injection systems, precision steel tubes, precision-turned components, and couplings for automotive, heavy-duty, marine, and mechanical engineering applications. The company also designs and produces modular TOPAQ hydrogen supply systems for zero-emission mobility, and a broad portfolio of specialized testing machines such as autofrettage systems, burst pressure testers, leak and impulse test stands, and e-mobility thermal management test benches.

Product overview

Poppe + Potthoff is a Tier 1 automotive supplier and precision engineering company that develops and manufactures sophisticated metal components and systems. The portfolio centers on three interconnected areas: precision components (common rail subsystems, precision steel tubes, precision-turned parts for braking/injection/safety systems, and R+W couplings), machine systems (autofrettage, burst pressure testing, leak testing, impulse testing, function testing, pressure generation, and measuring/testing equipment for validation of components), and hydrogen solutions (the TOPAQ modular hydrogen supply system with On Tank Valve, PCU, H2 Pipes, HPRU, and TPRD components for safe hydrogen transfer from tank to fuel cell or engine). The company also offers e-mobility test stands for thermal management testing of batteries and power electronics in electric vehicles.
