545 | Anderson Closed Inflatable Plugs - Small Sizes 3/4" to 1-1/4"

Inflatable plugs expand like a balloon inside pipes to seal off lines when pressure testing. They are not as durable as mechanical plugs, but provide a versatile solution for "out-of-round" plumbing or hard-to-reach locations. They can also be slid down the line to isolate sections of plumbing. Each plug comes with a standard tire valve attachment for inflataion. Adding an extension inflataion hose is recommended.
