The 3/4 inch SharkBite Push-to-Connect x MNPT Elbow allows you to make a 90 degree connection to 3/4 inch copper, CPVC or PEX pipe. SharkBite fittings are the easiest way to join pipe and do not require soldering, clamps, unions, glue or tools to complete the job. Just insert the pipe and the stainless steel teeth bite down and grip tight, while a specially formulated O-ring compresses to create a perfect seal. Disassembly is just as fast using the simple disconnect tool so fittings and valves can be easily changed and reused. They can even be rotated after assembly for easier installation in tight spaces. SharkBite fittings are certified for potable water supply and hydroid heating applications.
