Our story in the making...

Discover how 60 years of pioneering technology and precision engineering has built John Guest into the trusted brand we are today and continues to transform many industries.

Transforming the way we connect

Since 1961 John Guest has been making connections across many sectors. 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 pioneering products trusted by many global brands from Heineken to Ferrari.

Great engineering is about invention, design and the manufacture of practical solutions to complex problems. It’s the art and science of finding better ways of doing things. And that’s precisely what John Guest and JG Speedfit is famous for.

Evolving our technology

Speedfit Technology is built into the DNA of all our push-fit fittings. Its unique flexibility lies within its high performance, longevity of service, ease of installation and broad range of applications.

Fitted and demounted without using tools, our standard push-fit technology creates a strong and leak tight seal using a Grip & Seal cartridge with stainless steel teeth and main O-Ring seal.  We then take our core technology and develop advanced solutions to meet the unique needs of a wide range of industries. Working across diverse industries benefits everyone, as ideas and innovation are often applied from one sector to another.
