Closed Inflatable Plugs - Small Sizes (1/2" - 3")

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.

Required inflataion pressure varies by plug size and is noted on plug packaging and in this blog post.
