Each inflatable stopper comes with an inflation hose fitted with a Schrader valve enabling inflation with a standard airline, bicycle or foot pump. These inflatable stoppers are supplied as standard with no through tube. Through tubes can be supplied when the stoppers are required for weld purging applications. When deflated, the inflatable stoppers can be inserted and withdrawn with ease.
