Making fast cars even faster

Since 1961, John Guest has been by pioneering innovations to transform performance and efficiency for many industries, including automotive.

Our journey in automotive began in the 80s when Ford asked us to design a new fuel line connector. Compared to traditional metal connectors, our innovative push-fit technology made assembly much faster and simpler without the need for tools. Made from lightweight plastic, it also helped reduce the weight of vehicles leading to improved fuel consumption and acceleration rates.

Today, John Guest has become an integral component in many automotive OEM designs from fuel lines to brake systems, power steering, turbochargers and more.

Millions of our connectors are made each year and trusted by leading brands including Ford, Aston Martin, Ferrari, Mercedes, Porsche and BMW. Why? Because of the rapid assembly, high performance and versatility of our products for a wide range of vehicle applications.

Today, we offer an extensive range of push-fit connectors, cartridges, latch assembly kits and bespoke solutions for passenger vehicles, two wheelers, light commercial vehicles, speciality vehicles, and more. 

Blending engineering and manufacturing expertise with a high-quality service enables John Guest to develop bespoke solutions to meet the diverse needs of car manufacturers and automotive component manufacturers.

By working in close partnership and consultation, our push-fit technology can be easily integrated into your end product to improve design, assembly and processes. From initial problem-solving through to CAD design, prototype testing and phases up to full production, our team are on hand to provide expert technical advice and support.
