How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Drain Pipe Plugs
Seal unthreaded pipe ends with these plugs. They come with a band that clamps over the outside wall of your pipe and tightens with a screwdriver.
Plugs with a ventilation hole have a chamber with a ball that seals the plug when your pipe system is filled and purges air when it’s not.
Plugs with a faucet let you easily direct flow and drainage in your system.

Floor Drain Backflow Preventers
Put an end to water damage from backed-up sewers. To install, place a preventer into your floor drain pipe and tighten the screws—the rubber collar will expand for proper fit. When water backs up, the rubber float will rise to seal off the drain. When water recedes, the float will drop for normal drainage.
Square-Head Expansion Plugs
Turn the square head of the plug into the sealing ring to close off pipe openings. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.
