The end piece joint is sealed with an EPDM O-ring and thread locker. A.Y. McDonald ball valve curb stops offer positive shut-off from either direction and are available with a wide variety of end connections or Minneapolis Curb Box threads. A brass 2 in square operating head that is easily pinned to existing curb stops is available separately.
