About This Product

SharkBite ProLock fittings are a versatile and innovative full-flow Push-to-Connect fitting, desinged and engineered for use with PEX, copper, CPVC, PE-RT & HDPE Pipe. The intuitive design makes for one of the simplest and most dependable fittings on the market. No tools are required to make a connection. They use a collet with stainless steel teeth that grips the pipe when fully inserted and an EPDM O-Ring to provide a permanent, leak-proof seal. The Twist-to-lock feature ensures maximum security. When twisted into place with indicator arrows aligned, the locking cap locks the pipe in place. Removing the fitting is even easier with no special tools required, simply twist the cap counterclockwise to unlock then depress collet against the fitting to remove from pipe. ProLock fittings are suitable for hot and cold potable water and hydronic heating applications. Code approved for behind-the-wall installations. 25-year SharkBite System warranty when used with SharkBite pipe.

              what is the difference between pro lock and bite max and the appropriate applications.
              ByJun 25, 2024
              1 Answer | 
              Answer This Question

              Hello, Both fittings can be used in potable water and radiant heating applications. Both fittings can also be installed on PEX, Copper, CPVC and PE-RT. However, Sharkbite MAX is also compatible with HDPE SDR 9 piping making it more suitable for a wider range of applications. If you have any questions please contact our technical support team at 877-700-4242. Regards,

                  Coupling was very easy to install, can be removed and reinstalled easily, and was leak-free. It's length allowed for a slightly too short pipe cut to be able to be repaired with ease.

                  Built in wrong size
                  The online description for this item, the shark bite bag it comes in, and the engravings on the cast part itself say that the smaller end is 3/8. When I measure the diameter of the opening with a tape measure, it is 5/8. 3/8 inch tubing goes all the way through this adapter without touching any of it. Stay in school, kids

                    This Sharkbite coupling performed exactly as as I expected. One of the best features about it is how easy it is to connect and disconnect without tools.
