Multi-Size Inflatable Stoppers

Multi-Size Inflatable Stoppers

COB MLS and FXBP Plugs are made in the USA and usually in stock up to 60”, with larger sizes usually available within a week or two. *Also available in Nitrile and Neoprene for specialty applications.

 

COB Advantages
  • Used as a block plug, a water/air test plug, or leak locating back plug
  • Can be floated down pipe and stopped at desired location to prevent going down a manhole for installation or removal.
  • Grows shorter as it inflates to put less stress on plug.
