The long multi-size inflatable pipe plug DN 300–600 is made for large-diameter pipes, leak tests and temporary closures, also when there is a risk of flooding. Its stable round body is made in one piece without a longitudinal seam, and the fabric insert keeps it dimensionally stable.
The flexible natural rubber adapts to uneven pipe walls, and strong profiled grooves give a secure hold. 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.
