its resistance to corrosion and freezing.

easily disassembled and reused, together with its flexibility,
makes Speedfit ideal for this application.
Portable Buildings (offices, toilets): As with RV’s, Speedfit is
well suited for these applications.

MAKING A GOOD CONNECTION
Push the pipe into the fitting and up to the pipe stop.
Pipe Insert
John Guest Twist and Lock® Fittings have a collet with stainless
steel teeth that grip the pipe when fully inserted, and an O-ring to
provide a permanent leak-proof seal. The additional benefit of the
Twist and Lock fitting is that a twist of the screw-cap gives greater
compression on the O-ring seal and locks the pipe in place for
greater security.
Main ‘O’ Ring Seal
Stainless Steel Teeth Grip PipeSpacer
PREPARE THE PIPE
Speedfit Pipe
No Gap (locked)
Twist the screw-cap until it touches the body flange.
This locks the pipe into position and increases the
o-ring seal around the pipe.
Pull to check that it is secure. It is good practice to test the
system prior to leaving the site or before use. Our recommended
test procedure is shown in our Technical Checklist.
TO DISCONNECT:
Ensure that the system is depressurized.
Pipe Cutter
JGTS
To prevent damage to the O-ring remove all burrs and sharp
edges. When using Speedfit® or other types of PEX Pipe, we
recommend the use of Pipe Insert.
HOW TO MAKE A CONNECTION
Fittings and pipe should be kept clean, bagged, and undamaged
before use.
TWIST AND LOCK FITTINGS
Gap Between Cap and Flange
The fitting should be in the ‘unlocked’ position. This is shown by a
small gap between the screw-cap and the body flange.
Pipe Stop ‘O’ Ring Collet
Spacer
Be sure to twist the screw-cap back to the unlock position.
Push the collet square against the face of the fitting by using
fingers. With the collet held in this position the pipe can be
removed.
The fitting can be used again without the need for replacement
parts. (Ensure the fitting is clean before every use).
WHAT NOT TO DO
• Do not use damaged or scored pipe
• Do not use a hacksaw to cut the pipe
• Do not leave burrs on the end of the pipe
• Do not forget to push the pipe fully into
the fitting, past both the collet (gripper) and the O-ring.
• Do not insert fingers into the fitting as the stainless steel teeth
may cause injury.
Remember to pressure test the completed installation according
to the recommendations in our Technical Checklist.
