Quick-Snap Expansion Plugs
Turn the cam handle to expand the seal, then snap the handle down to hold it in place and 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.
Plugs with a zinc-plated steel plate have fair corrosion resistance.
Plugs with a stainless steel plate have excellent corrosion resistance.

Expansion Plugs for Cleanout Tees
Seal cleanout tees when testing your drain, waste, and vent systems for pressure and leaks—no need to inflate these plugs with an air compressor or hand pump. To install, insert the plug end into your pipe so the curved foot is on the bottom threads of the cleanout tee, then push down the handle to lock it into the foot. The foot has a two-stage release latch: lift the handle one notch to release the plug and allow liquid to drain slowly, then lift the handle again until the foot fully disengages to take out the plug.
