Gaslock – fuel caps, accessory parts, level indicators & IOT
Gaslock - Sensoren, Tankverschlüsse, Zubehörteile und Füllstandsanzeiger
In addition to the realization of our own product ideas, we also develop and manufacture customer-specific products. You too can benefit from our many years of experience, our highly flexible production and a worldwide supplier network. We often integrate different technology carriers in the development of new products. In this way, it can happen that components or technologies that are rather untypical for an application give the product additional functions and thus create unique selling points. Our own development department for electronic circuits as well as 3D package development work with compatible software solutions. The PCB layout can thus take the housing design into account – and vice versa.

Our state-of-the-art SMD circuit board production, which is optimized for flexibility, our own high-performance plastic injection molding shop, our partially automated cable harness production, 30 assembly workstations and our in-house packaging line enable short delivery times and flexible order processing – especially for small to medium-sized series.

Our History
Birth of Gaslock GmbH
The origin of our company lies in a motorcycle dealership with Harley-Davidson representation of the motorcycle mechanic master and Gaslock founder Jörg Lienenkamp. During this time, there were repeated requests for lockable Harley tank caps. Since there was no offer at that time, Jörg Lienenkamp developed a solution on behalf of Harley-Davidson, first with an automotive supplier and from 1998 on his own. That was the birth of Gaslock GmbH.
To the specialist for technology products
The development of complex and technically high-quality products in small and medium series quickly became our specialty. Confidence in the team around Managing Director Jörg Lienenkamp grew, so that Harley-Davidson commissioned us with the development of further accessories. These include oil dipsticks and tank gauges.
Our team supplemented these core products with a first in-house development in 2005. As an accessory for vehicles, we introduced the INDY-CATOR®, an LCD gear indicator shift knob for manual transmissions, to the automotive aftermarket. Further variants of the INDY-CATOR® followed.
The next major innovation and entry into the leisure market, among others, came in 2010 with the GASLEVEL® gas level indicator based on ultrasonic sensor technology. The handy device measures gas levels in propane cylinders, e.g. for camping, boats and outdoor heaters. For the international market we have developed the GASLEVEL® Stick.


Gaslock Produktion - Alles aus einer Hand. Von der thermoplastischen Kunststoffverarbeitung bis zur SMD Platinenbestückung

Our production facilities for lockable fuel caps, oil dipsticks, fuel level indicators, gear indicators and gas level indicators are state-of-the-art and partly developed in-house. In this way, we ensure high product quality, as demonstrated, for example, by the long-standing business relationship with Harley-Davidson that has existed since Gaslock was founded.

Electronic modules
Our solder paste printers, SMD technology (component placers) and vapor phase soldering machines, which are optimized for flexibility, enable us to produce boards (printed circuit boards) of the highest quality, low reject rates and highly flexible order processing.

Some of our PCBs and sensors are overmolded with thermoplastics on our injection molding machines. Here we have gained a lot of experience in the so-called “over-molding”.

Manual assembly
In final assembly, our well-trained specialists work at ergonomically designed workstations. Depending on the product, we assemble in island assemblies or individual assembly lines. Our packaging line is flexible in use.

Engravings, inscriptions
Whether stainless steel, aluminum, brass or plastic – we mark (label) our products at the end of the production process by laser engraving and pad printing.

Since 1998, we have been developing and producing lockable tank caps for Harley-Davidson motorcycles and gear indicators for the automotive industry since 2005. We quickly expanded our product portfolio and developed level indicators for oil, gasoline, gas and water. More than 15 years after the foundation of our company, we have comprehensive technical competences:
