  • These Multi-Flex plugs feature ballistic nylon reinforced polyurethane construction for prolonged use.
  • They have a small deflated plug diameter for allowing insertion through a small hot tap.
  • They can withstand pressures up to 200 psi and have deflated plug diameters ranging from 1 to 41 inches.

Compatible Accessories
