Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Also known as Schedule 10 fittings, these are thin, lightweight, and corrosion resistant.

For a leak-tight connection, crimp the press-connect fittings on these valves to metal tubing with a crimping tool—no heat or soldering required. They open and close gradually as the wheel handle turns, preventing sudden starts and stops of flow.
