SharkBite 3/4 x 3/4 Inch FNPT Threaded Adapter, Push To Connect Brass Plumbing Fitting, PEX Pipe, Copper, CPVC, PE-RT, HDPE, U766LFA Product Description CUT. PUSH. DONE. One side has a copper tube sized (CTS) tailpiece adapter that can be pushed into any SharkBite fitting. The other side has a FNPT connection. The SharkBite Connection System makes any plumbing project fast and easy thanks to unique push-to-connect technology. When you insert a pipe into a SharkBite quick-connect fitting, the fitting's stainless-steel teeth bite down and grip the pipe, while its special O-ring compresses to create a watertight seal. No soldering, no clamps, no glue. SharkBite products work with your existing plumbing, are easy to disassemble for changing and reusing fittings, and can be rotated for installation in tight spaces. Whether you need to repair a broken pipe or plumb a whole house, SharkBite provides a push-to-connect solution and leak-free results. From the Manufacturer Shark Bite push-fit fittings are the fastest, easiest way to join copper, CPVC and PEX in any combination-wet or dry-with no soldering, clamps, unions or glue. 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.
