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.
