Types of Drain Outlets

HUB OUTLET (OUTSIDE CAULK OUTLET): A drain connection, usually on side outlet drains, where plain end of drain pipe is inserted and a seal is made either by caulking or by using a compression gasket. This type of outlet is the opposite of the inside caulk outlet.

INSIDE CAULK OUTLET: Open bottom type drain connection which is placed over plain end of drain pipe. The seal is then made by caulking or with a compression gasket. This type of outlet is the opposite of the hub outlet.

SPIGOT OUTLET (NO HUB OUTLET): Male, pipe size, plain end connection for caulking into a soil pipe hub or joining to plain end pipe with a mechanical coupling.

THREADED OUTLET (TAPPED OUTLET): Internally threaded drain connection for joining drain to a threaded pipe drain line with American Standard & Taper pipe threads (NPT).

PUSH-ON OUTLET: "Push-on" is a unique labor saving compression gasketed connection designed to simply push on the stub end of the pipe. The Push-on drain body and gasket can be utilized with plastic, steel, No-Hub and service weight soil pipe. A unique pipe stop cast in each drain body ensures that water will not accumulate around the connecting pipe.
