SharkBite EvoPEX 3/4" x 1/2" x 3/4" Push to Connect Reducing Tee Fitting. #K444A
Pack of 1
SharkBite's EvoPEX Tees are engineered to improve efficiency and enable plumbing contractors to optimize install time with clean, leak-free PEX installations.
With no soldering, clamps, unions or glue required, it's as simple as applying Teflon tape to fitting threads and inserting PEX pipe into the fitting deep enough to be sealed by our specially-formulated O-ring. 
Once inserted, the stainless steel teeth bite down and grip the pipe. 
A green indicator ring will appear in four slots around the fitting to visually display that the permanent inner-diameter connection is secure. 
This push-to-connect fitting is designed make PEX-to-NPT connections in potable water and radiant heating (including underground or behind-the-wall) applications with no access panels required. Fittings are rated to 80 psi @ 200°F, 100 psi @ 180°F, and 160 psi @ 73.4°F.
