Brand heritage and specialisms
John Guest founded his precision-engineering and toolmaking business in 1961 with an emphasis on product quality, service and practical innovation. Early work for pneumatic manufacturers led the company towards a new way of connecting pipe and tube.
In 1974 John Guest created Super Speedfit, described by the company as the first push-fit solution for compressed air. Development across automotive, beverage and telecommunications followed, before the JG Speedfit plastic push-fit plumbing and heating system launched in 1987.
The modern range spans fittings, pipe, valves and fluid-control products for plumbing, heating, water treatment, drinks dispense, pneumatics and original-equipment applications. Tube material, diameter, pressure, temperature, medium and approval requirements must be checked for every connection.
Power-Hub carries John Guest across plumbing, pneumatic and fluid-connection categories. The live category ranking below shows the strongest areas of the current catalogue, followed by five featured products available through the store.
