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.
