• Inflatable PVC Sealing Bags are ideal for use in areas where access is smaller than the test diameter, or where the test area is some distance from the access point. • Bags are fitted with a Schrader Valve for inflating the Bag. • Use a Foot Pump or Bicycle Pump to inflate. • Maximum care must be excercised when inflating the Bags. • Rapid inflation will lead to the Bag bursting. • With care, Bags can be inflated to the maximum size shown in the Table. • DO NOT try to over inflate. • At the maximum inflation, the sealing area will be severely restricted, reducing the maximum allowable Back Pressure. • Pipe: Ø 124-160 mm
