The concept of push-in fittings was pioneered by John Guest and there are now many millions in service around the world.
As more and more installers and Original Equipment Manufacturers begin to see the benefits in labour saving and reliability offered by our fittings the old methods of tube connection, such as compression and barb fittings, are being replaced by push-in technology.

We now offer a comprehensive range of over 3,000 products addressing virtually every tubing and pipe connection requirement imaginable.

Across a host of applications, John Guest fittings require no special tools.
Simply cut the tube square and insert it into the fitting to effect a secure and reliable connection.

Thus, our products offer the most reliable and cost effective solution to tubing connections.

We invite you to browse our products so that you can see for yourself how John Guest fittings can help your company make the right connection - first time, every time!
