A commitment to quality is at the heart of the John

Guest philosophy.

The strictest control is maintained by virtue of the fact that

design and manufacture is carried out in modern purpose built

manufacturing centres in west London and at Maidenhead in

Berkshire. Maintaining control over the whole process from

initial tool design and tool making through to final assembly

and testing ensuring that only products of the highest quality

are produced. The company believe it is this commitment to

quality that has led to it receiving prestigious awards from

many of the worldʼs leading testing and approvals

organisations. John Guest is a preferred supplier to many

international companies. John Guest offer the widest range

of push-in fittings, tube and other fluid control products for

drinks dispense and pure water applications.

Pushing the tube into the fitting is all that is needed to produce an instant but permanent leakproof connection. The fittings are just as easy to disconnect and re use without the need for replacement parts. The products in this catalogue are produced in FDA compliant materials making them especially suitable for potable liquids. Selected items can also be used for inert gases such as CO2.

They are also recommended for intermittent hot water applications. Selected items are available with red or blue collets.
