The SharkBite
®
connection system is certified for potable water and hydronic applications. SharkBite uses an
advanced push-to-connect design that works in two stages. When the pipe 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 pipe. At the second stage the pipe is pushed through an o-ring protector which
aligns the pipe. A specially formulated o-ring is then compressed between the wall of the fitting and the pipe
before the end of the pipe reaches the tube stop.
Only when the pipe 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)
PE-RT (ASTM F 2769)
HDPE (SDR-9 ASTM D2737)
The SharkBite fittings have an integral PEX Stiener
that is eective in supporting PEX, PE-RT, and HDPE
tubing to ensure the o-ring seals correctly on the
outside of the pipe. The PEX Stiener is not required
for use with CPVC and copper tubing, however these
two types of tubing fit over the PEX Stiener easily
and hold it against the tube stop.
