Watts 3501-0808 Aqualock Pex Quick Connect Male Adapter, 3/8 X 1/2 In.

The Watts Aqualock 3501-0808 is a quick-connect male adapter designed to join PEX, copper, or CPVC tubing to 1/2-inch male pipe thread fittings without requiring any installation tools. This push-to-connect fitting simplifies both new plumbing installations and repair projects by eliminating the need for soldering, crimping, or flaring—making it ideal for DIY homeowners and professional plumbers alike.

The quick-connect design allows for quick and easy connections. Simply cut your tubing, push it into the fitting until it seats at the internal stop, and you're done. If you need to disconnect later, just pull back on the retaining ring and release the pipe.
