Transforming the way we connect

Since 1961, we’ve been transforming the delivery of fluid, air and data with our push-fit connection technology. As well as our pivotal role in plumbing, we also invented the world’s first push-fit system for compressed air and telecoms, with new products developed for brands from Heineken to Ferrari.

Great engineering is about innovation, design and the manufacture of practical solutions to complex problems. And at John Guest we aim to embody these principles in all our products.
