Fuel caps and gauges

We have developed and produced self-locking fuel caps for Harley-Davidson motorcycles since 1998 and gear indicators for the automotive industry since 2005. Since then we rapidly expanded our product portfolio by developing level indicators for oil, fuel, gas and water. With over 15 years of experience we now have an extensive range of technological expertise:


  • As a medium-sized company we specialize in the manufacture of complex mechanics (e.g. fuel caps) and level indicators on a small to medium scale.
  • At our production site in Iserlohn we have modern production facilities as well as well-trained and skilled staff. We ensure our high standard of product quality "made in Germany" by means of a sophisticated quality management system (DIN ISO 9001:2008).
  • Due to our longstanding collaboration with Harley-Davidson and automobile manufacturers we are familiar with requirements in terms of visual and tactile impression it comes to technical products with a high degree of emotional appeal.
  • Managed by founder and master motorcycle mechanic Jörg Lienenkamp, our company manufactures outstandingly crafted products with great attention to detail.
