Instruction #2 - Install Tubing to Quick Connect Fittings
PLASTIC TU ING
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. Ma e sure outer surface of tube is
clear of mar s 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 lea age.
QUICK-CONNECT FITTINGS
Fittings consist of two parts: a Body and
a collet.
1. To install a tube, push it through
Collet until it seats firmly at bottom of
fitting (Figure A and B.).
2. To remove a tube, push and hold
Collet against Body while pulling tube
out (Figure C).
A. Push tube through Collet into Body. B. Tube must seat firmly at bottom
of fitting.
C. Push Collet against Body to
release tube.
