How to use the quick connect fittings on the RO Module
To make a connection, the tube is simply pushed into the fitting. Place a piece of tape 1/2" from end of tube
to indicate how far the tube should be inserted. The unique patented John Guest® locking system holds
the tube firmly in place without deforming it or restricting flow.
Cut the tube square. It is essential that the outside
diameter be free of score marks and that burrs and sharp
edges be removed before inserting into fitting.
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.
Fitting grips before it seals. Ensure tube is pushed into
the tube stop.
Pull on the tube to check that it is secure. It is a good prac-
tice to test the system prior to leaving site and /or before
use.
To disconnect, ensure the system is depressurized be-
fore removing the tube. Push in collect squarely against
face of fitting. With the collect held in this position, the
tube can be removed. The fitting can then be reused.
