The long multi-size inflatable pipe plug DN 200–500 is suited to demanding sealing work in sewers and pipes and to flood protection. Its robust round body is made in one piece without a longitudinal seam, from fabric-reinforced natural rubber, and adapts to different pipe materials.
Strong profiled grooves prevent slipping. The plug is inflated through the compressed air coupling with a compressor or air pump. The sturdy eye on the front is used to secure the plug with a safety line, available separately as an accessory.
