PLUG LONG FOR PIPE 200 - 400 MM Ø WITH COMPRESSED AIR ADAPTER

The long multi-size inflatable pipe plug DN 200–400 is made for professional use in pipe sealing, repair work and flood protection. Its stable round body is made in one piece without a longitudinal seam, from natural rubber with a fabric reinforcement.

Non-slip profiled grooves give a secure hold in the pipe. The plug is inflated through the compressed air coupling; a compressor or a hand pump is sufficient. The sturdy eye on the front is used to secure the plug with a safety line, available separately as an accessory.
