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.

Zinc-Plated Steel Plate—Plugs with a zinc-plated steel plate have fair corrosion resistance.

Stainless Steel Plate—Plugs with a stainless steel plate have excellent corrosion resistance.

Maximum Air Back Pressure—Maximum air back pressure is the amount of pressure a plug can withstand without moving.

Maximum Water Back Pressure—Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.

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.

Maximum Air Back Pressure—Maximum air back pressure is the amount of pressure a plug can withstand without moving.

Maximum Water Back Pressure—Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.
