User Guide
Like our Standard Fittings, 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.
PREPARE THE PIPE 
To  prevent  damage  to  the  O-ring  remove  all  burrs  and  sharp 
edges. When using Speedfit Pipe, we recommend the  use  of  a 
Pipe Insert. The insert should only be used with Speedfit Pipe.
HOW TO MAKE A CONNECTION
Fittings and pipe should be kept clean, bagged, and undamaged 
before use.
TWIST AND LOCK FITTINGS
The fitting should be in the ‘unlocked’ position. This is shown by a 
small gap between the screw-cap and the body flange.
Push the pipe into the fitting and up to the pipe stop. 
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.
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 tting, past both        
 the collet (gripper) and the O-ring.
• Do not insert ngers into the tting as the stainless steel teeth     
 may cause injury.
Remember to pressure test the completed installation according 
to the recommendations in our Technical Checklist.
