Quick connect fittings 

Many RO systems utilize Quick Connect fittings. These user-
friendly  fittings  provide  superior  performance  and  may  be 
provided with this system. Proper use of these push-in fittings 
is  shown  below.  Along  with  these  fittings,  all  tubing  selected 
must  be  of  high  quality  and  must  be  cut  with  a  plastic  tube 
cutter or sharp razor with a clean, square cut. 
 

How to make a connection:

 

1.  Cut the tube square 

 
 
 
 

  Cut the tube square. It is essential that the outside diameter 

be free from score marks and that burrs and sharp edges 
be removed before inserting into fitting. For soft thin walled 
tubing we recommend the use of tube inserts. 

 
2.  Insert tube 

 
 
 
 

  Fitting grips before it seals. Ensure tube is pushed fully into 

the tube stop. 

3.  Push up to the 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 secure 

 
 
 
 

 

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

 

Disconnecting 

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 be re-used. 

 
 
Should a leak occur at a fitting, the cause is generally defective 
tubing. To fix a leak, relieve pressure, release tubing, cut off at 
least  1/4”  from  the  end  (square  cut),  reattach  the  tubing  and 
confirm  the  connection  is  leak  free.  Each  time  a  new 
connection is made, it is advisable to cut off 1/4” from the end 
of the tubing using these fittings.
