Since 1961, John Guest’s pioneering innovations have been transforming performance and efficiency for many industries. Back in the 70s, John Guest invented push-fit technology that revolutionised the way connections are made.

Market leaders and niche players have been using our technology for decades to solve the key challenges they face. Why? Because the clever science behind our technology ensures optimal performance, longevity and fast and simple installation.

From distilling wine to hydroponic farming to animal feeding equipment, environmental test chambers and fuel cells, the OEM applications are endless.

JG OEM Cartridge

Blending engineering and manufacturing expertise with a high-quality service enables John Guest to develop customised solutions to meet the needs of many different customers.

By working in close partnership with you, we integrate our push-fit technology into your own branded products. From initial concept to CAD design, prototype testing through to full production, our teams are on hand to provide expert advise and support every step of the way.

Here are some examples of the type of projects we get involved in.

  • Venturing into the jungles of Indonesia 

    Teaming up with LightWell, who design and build self-contained water purification and lighting units, we helped remote communities get the clean and fresh water they need. Using John Guest push-fit products, these units were simple to install and integrate, which was a key requirement, as they were fitted in hard to access areas. 

  • Battling the heat in Spanish supermarkets

    Ramarpul creates humidification and evaporative cooling systems for multiple industries. John Guest push-fit connectors are used in their misting system, which sprays the fresh produce at intervals, providing consistent moisture and cool air. Connecting all the pipes within the system, our leakproof JG push-fit fittings can also be assembled and disassembled quickly for repair or maintenance. 

  • Home brewers take the chilled approach

    Brewolution, a Danish company specialising in the home brewing market, specified our products in its private beer brewing solution, due to their easy and fast installation.  Our John Guest fittings are used to help manage the flow control of wort, the unfermented beer, in their home brewery system.

  • Inspiration, invention, infusion

    AEG needed a solution to make the resin infusion manufacturing process, widely used in the marine, aviation, automotive, and industrial sectors, safer and more efficient.  John Guest OEM cartridges were selected to incorporate into their system. When the system is under pressure, the quick push-fit connection applies more grip to ensure a strong seal. Preparation and setup are also quicker, helping make the entire process more efficient. It also lowers waste  as components are reusable within a normally single-use application.

  • Spraying a little innovation on the agriculture world

    Altek was looking for a solution for their agricultural sprayers to improve the chemical processing of vegetable produce. Incorporating our push-fit technology, which is UV stabilised and resistant to liquids from various chemical compositions, improved the efficiency of Altek’s system, while making it easier to install, amend and repair. It also reduced the requirement for electrical power.
