How to Use Quick-Connect Fittings
INTER-COMPONENT CONNECTIONS
Connections between cold water supply line, RO Module, storage tank, product water faucet, and drain line are
accomplished using plastic tubing and push-together quick-connect type fittings.
PLASTIC TUBING
1. Cut tube ends square and straight. Do not deform tube
(i.e., cause tube to compress its diameter so it is no
longer round).
2. Make sure outer surface of tube is clear of marks or
scratches for a length equal to twice tube diameter. This
allows “O” ring to seat properly against tube.
3. Avoid sharp changes in direction when routing tubing.
Sharp turns cause tubing to flex and deform, which
reduces its flow capacity and may increase lateral stress
on the fittings, causing leakage.
QUICK-CONNECT FITTINGS
Fittings consist of two parts: a Body and a colored collet
and symbol. Collet color and symbol corresponds to tubing
to be used at that connection (Figure 2.A.).
1. To install a tube, push it through Collet until it seats
firmly at bottom of fitting (Figure 2.A and 2.B.).
2. To remove a tube, push and hold Collet against Body
while pulling tube out (Figure 2.C.).
