Tips for Making a Proper Connection

SuperSpeedfit® Push-In Fittings Connection

This simple concept pioneered by John Guest over 30 years ago now embodies a comprehensive line of over 3,000 products addressing virtually every tubing connection requirement. Our Super Speedfit® range of push-in fittings is manufactured in acetal copolymer, polypropylene, and brass and are available in inch and metric sizes. They have been developed for applications involving foodstuff, potable liquids, air, inert gasses, CO2 lines and pneumatic and vacuum systems. In all applications John Guest SuperSpeedfit® fittings require no tools. Tubing is simply inserted into the fitting collet and past the ‘o’ ring to the tube stop to effect a secure connection. Whether plastic or soft metal tubing is used, the integrity of the connection is assured. Super Speedfit® push-in fittings afford the most reliable and cost effective solution to tubing connections.

NOTE: Do not apply glue to the bottom of fittings!

The Materials of Construction

The fittings are made up of three components:
1. Bodies are produced in acetal copolymer or polypropylene.
2. ‘O’ rings are nitrile rubber or EPDM.
3. Collets are produced in acetal copolymer or polypropylene with stainless steel teeth.

Making the Connection

To make a connection, the tube is simply pushed in by hand. The unique patented John Guest collet locking system then holds the tube firmly in place without deforming it or restricting flow.

1. Cut Tube Square

To make a connection, the tube is simply pushed in by hand. The unique patented John Guest collet locking system then holds the tube firmly in place without deforming it or restricting flow.

2. Insert Tube

Fitting grips before it seals. Ensure tube is pushed into the tube stop.

3. Push Up to Tube Stop

Push the tube into the fitting to the tube stop. The collet (gripper) has stainless steel teeth, which hold the tube firmly in position, while the 'O' ring provides a permanent leak proof seal.

4. Pull to Check if Secure

Pull on the tube to check that is is secure. It is a good practice to test the system prior to leaving site and/or before use.

How to Disconnect

Push in Collet and Remove Tube

To disconnect, ensure the system is depressurized before removing the tube. Push in collet squarely against face of fitting. With the collet held in this position, the tube can be removed. The fitting can then be re-used.
