The SharkBite
®
System
The SharkBite
®
connection system uses
an advanced push-t design that works
in two stages. When the tube is inserted
into the tting it passes the rst stage
through a release collar and then through a
stainless steel grab ring. The grab ring has
teeth that open out and grip onto the tube.
At the second stage the tube is pushed
through an o-ring protector which aligns the
tube. A specially formulated o-ring is then
compressed between the wall of the tting
and the tube before the end of the tube
reaches the tube stop.
Only when the tube has passed through
the o-ring and reaches the tube stop, is
a secure joint created. The SharkBite
®
ttings can only be used with pipe/tubing
certied to the following specications:
• PEX (ASTM F876, CSA B137.5)
• Copper (ASTM B 88)
• CPVC (ASTM D 2846, CSA B137.6)
The SharkBite
®
ttings have an integral
Tube Support Liner that is effective in
supporting PEX tubing to ensure the
o-ring seals correctly on the outside of the
PEX tubing. The Tube Support Liner is not
required for use with CPVC and copper
tubing; however these two types of tubing
t over the Tube Support Liner easily and
hold it against the tube stop. But the tube
liner may be easily removed based on
preference or local codes – see page 5
for details.
