THE SHARKBITE
®
CONNECTION SYSTEM
The SharkBite
®
connection system uses an advanced push-fi t design that works in two stages.
When the tube is inserted into the fi tting it passes the fi 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 fi 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
®
fi ttings can
only be used with pipe/tubing certifi ed to the
following specifi cations:
• PEX (ASTM F876, CSA B137.5)
• Copper (ASTM B 88)
• CPVC (ASTM D 2846, CSA B137.6)
The SharkBite
®
fi 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 fi 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 4
for details.
