All around the world, John Guest’s push-fit technology is changing the way pipe and tube connections are made. From the New Zealand coastline to the beating heart of the Thames Valley, John Guest is present in diverse applications.

Read below to learn more about 5 of our most unusual projects!

1. Polarclean takes its place in Irish history

Our Polarclean tube-in-tube technology is being used by Guinness owner, Diageo, as part of an upgrade across 1,500 sites in Ireland.

JJ Finan, one of the trial sites, is famous for playing host to some of Oasis’s early performances as the Gallagher family hail from the local area of Charlestown.

Polarclean optimises draught dispense quality due to its uniquely efficient temperature conditioning of beer whilst in the line. Therefore, John Guest’s legendary Speedfit technology stands amongst other legends of a more musical kind!

We go to Poland for this fascinating story. URSUS is the oldest brand of vehicle and agricultural machinery in its country, with its name coming from a well-known Polish novel with the strongman hero named Ursus.

Its latest selection of tractors feature John Guest push-fit connectors in the fuel system; having been awarded a contract for over 5 thousand tractors and agricultural machines in Zambia, it allows us to get our brand out into new and unchartered markets.

3. JG can’t stop carping on about algae feed

New Zealand’s Cawthron Institute, the leading independent science organisation in the country, found John Guest’s push-fit fittings the perfect solution to help develop algae feeding equipment.

They required a system that was easy to assemble and disassemble as well as easy to clean. Moreover, our push-fit fittings helped maintain a high level of sterility, which is something traditional fittings couldn’t have allowed for.

Who’d have thought you’d find a JG fitting alongside shellfish, but that exemplifies what’s so great about the technology – it works for any situation.

It’s been such a success that the biotechnologist is passing the equipment on to other New Zealand algae culturing farms. Fantastic result!

4. Breathing easy just got even easier

John Guest provides Artecer, a Portuguese manufacturer of equipment for inhalation therapy and balneotherapy, a range of push-fit fittings and pipes that make their equipment easy to assemble.

Balneotherapy is a unique type of treatment which involves using mineral springs to treat diseases. Most importantly, our push-fit fittings and pipe ensure a high level of hygiene is maintained through eliminating sources of contamination.

5. John Guest’s technology reaches new heights with the next generation

A more personal touch for this final story as a JG employee Geoff Saunders and his son Harrison developed a challenge for Upton Cubs in Slough.

Geoff is the assistant section leader at JG who developed a challenge to propel a plastic bottle rocket as far as possible, along with his son.

By using a John Guest 15mm stopdouble check valveSpeedfit pipe and car tyre valve they managed to send the rocket flying 80 feet. Well done!

We’re sure it’s only a matter of time before NASA get in touch and they’ll be using John Guest to get man back on the moon!
