System
The SharkBite
®
connection system uses an advanced push-fit design that works in two
stages. When the tube is inserted into the fitting it passes the first 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 fitting 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
®
fittings can only be used with pipe/tubing certified to the following
specifications:
PEX (ASTM F876, CSA B137.5)
Copper (ASTM B 88)
CPVC (ASTM D 2846, CSA B137.6)
The SharkBite
®
fittings 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 fit 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.
