THE SHARKBITE
®
CONNECTION 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 4
for details.
