John Guest Equal Elbow 3/8″ – 3/8″
John Guest offer the widest range of push-in fittings, tube and other fluid control products for drinks dispense and pure water applications.
The world’s first food quality push in fitting, the John Guest range is now over 800 items strong and provides the quickest and most effective of installations.
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 approved materials making them especially suitable for potable liquids. Selected items can also be used for inert gases such as CO2.
How Super Speedfit works
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.
Materials of construction
Super Speedfit fittings are made up of three components:
Bodies are produced in an acetal copolymer or polypropylene.
O-Rings are nitrile rubber or EPDM.
Collets are produced in acetal copolymer or polypropylene with stainless steel teeth.
How to make a connection
Cut the tube square and remove burrs and sharp edges. Ensure the outside diameter is free of score marks. For soft or thin walled tube we recommend the use of a tube insert.
Push the tube into the fitting, to the tube stop.
Pull on the tube to check it is secure. Test the system before use.
To disconnect
Push in collet and remove tube. To disconnect, ensure the system is depressurized, push the collet square against the fitting. With the collet held in this position the tube can be removed.
Grey Acetal Fittings
PI fittings offered in sizes 5/32” to 5/8” are manufactured in grey acetal copolymer, making them especially suitable for applications involving foodstuffs and potable liquids. They are however equally suitable for air and inert gases and can be used on N2/CO2 (installed in accordance with The British Beer and Pub Association Code of Practice) mixed gas dispense lines and in pneumatic applications and vacuum.

Maximum Torque Values for Plastic Threads BSP, BSPT & NPT.
Plastic threads are not generally as strong as brass threads. Customers and end users should be aware of this when choosing products for their applications. Overtightening of plastic threads will cause undue stress and eventual cracking and leakage. The maximum torque figures for BSP and BSPT threads used on John Guest fittings in mating threads conforming to the relevant BS or International thread standards are shown below.
Threads 1/8-1/4 3/8 1/2
Max. torque 1.5Nm. 3.0Nm. 4.0Nm
