The high-pressure inflatable pipe plug DN 200–300 works with an inflation pressure of 6 bar and holds a back pressure of up to 3 bar. It safely closes pipes and sewers with a diameter of 188 to 315 mm. Its round body is made in one piece without a longitudinal seam, from very robust natural rubber with a fabric insert.
The material adapts well to all pipe materials, and slight unevenness is no obstacle. Strong profiled grooves give a secure hold in pipes and sewers. The plug is inflated through the compressed air coupling.
