John Guest started his engineering business from a small tool shop in 1961, driven by the desire to solve complex challenges with smarter, simpler and more reliable solutions. His first major breakthrough was the design of game-changing tube connection technology, originally for compressed air.

During the 1980s, John Guest developed products to meet the exacting performance and safety standards for the drinks, automotive and telecoms sectors. When Ford needed a fitting for its fuel lines, they turned to John Guest. And working in partnership with BT, John Guest invented the world’s first push-fit fibre optic connection.

In 1987, the JG Speedfit plastic push-fit system was born. This iconic brand revolutionised the modern world of plumbing, enabling secure, safe pipe connections to be made in a fraction of the time taken traditionally.

New product development for countless applications continues. But, as well as invention, the John Guest name has become synonymous with quality and service thanks to rigorous design and testing standards and a business run on shared values.

Today, our UK factories make billions of products that are used and trusted worldwide. Everything is made on site from our tooling to our components, ensuring the John Guest reputation for reliability and service.
