SharkBite push-to-connect fittings are the core products within the SharkBite System, and provide the easiest and most dependable way to join PEX, copper, CPVC, HDPE or PE-RT pipe in any combination without solder, clamps, unions or glue. When you insert the pipe, the stainless steel teeth in our push-to-connect fittings bite down and grip tight, while the specially formulated o-ring compresses to create a perfect, secure seal.

Pipe insertion depths for SharkBite fittings vary depending on the size of the fitting. Up-to-date pipe insertion depths can be found here.

NOTE: The tube liner is necessary for use with PEX, HDPE or PE-RT Pipe. It is not required for copper or CPVC, however, it is not necessary to remove the tube liner from the fitting.

SharkBite fittings can leak due to one of these reasons:

• The pipe was not properly deburred prior to installation.
• The pipe was not properly inserted.
• The pipe was not squarely cut.
• The pipe has scratches or debris on the outside that is preventing the O-ring from getting a watertight seal.

Review installation instructions to ensure you've followed the correct steps. If still having issues, don't hesitate to contact our support team.

Water systems should not be allowed to freeze. When water freezes, it expands and creates pressure that exceeds plumbing system pressure capabilities, i.e. pipes and fittings burst.

It is recommended to solder any joints prior to installing a SharkBite fitting. The heat from the torch can be transferred through the pipe and potentially damage the O-ring.
