John Guest

John Guest is a UK manufacturer of push filt fittings for a wide range of industries and applications including water purification. 

We use John Guest fittings and plastic tubing in our water filters for home and business. 

John Guest push fit fittings ensure fast, simple, and secure connections in any water filtration product. 

We wouldn't use anything other than John Guest push fittings. They're simply the best, which is why we stock a range of John Guest pushfit that you can buy as single units. It's amazing how many people just need one or two fittings, and don't want to buy large quantities. Take a look at our water filter parts section for more components.
