Often used for plumbing tests, these plugs thread into tees and inflate to block flow across the pipe.

These extra-long plugs allow you to seal off two pipes at the same time. They have two separate inflation chambers to release back pressure gradually and prevent splash back as water clears the drain line.

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve back pressure while testing.

Tighten the nut on these plugs to expand the seal.

Twist the easy-grip T-handle on these plugs to expand the seal.

Turn the cam handle to expand the seal, then snap the handle down to hold it in place.

Insert these plugs deep within your pipe to temporarily block off a line. Twist their wing nut to expand the seal.

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.
