Quick Connect Fittings have been designed for a wide range of applications offering a fast and safe method of connecting pipes.

John Guest fittings can be divided into two types:

A) unit of measurement in millimeters, usually black (metric system).

B) unit of measurement in inches, usually gray in color (imperial Anglo-Saxon system).

The fitting consists of three elements:

The acetal copolymer plastic body, the acetal copolymer tweezers with the stainless steel teeth and the non-toxic nitric rubber oring.

These characteristics make them usable for food liquids, compressed air, co2 and other gas mixtures.

Features of John Guest fittings:

Wide range of sizes available

Quick connection and disconnection

Possibility of reusing both the fittings and the tube

The use of tools is not necessary

High mechanical resistance

Non-toxic materials approved by the FAD (Food and Drug Administration)

The product complies with EEC standards for food products

Practical advice:

For correct installation, check that the pipe is free from scratches and that it is deburred before insertion into the fitting.

The John Guest fitting should not be tightened strongly: it must be tightened by hand and if you use the key, max half a turn more than the hand lock.

Making a joint:

○ Cut the pipe perpendicularly ○ Push the tube into the fitting as far as it will go ○ Check the tightness by pulling the tube

Disconnection: ○ Before disconnecting, make sure that the system is depressurized. ○ Push the tube and the tweezers towards the fitting and remove the tube.
