Description
Overview:
The Goodman Type gas stopper bag is available in sizes 50mm and above and comes complete with a 450mm long neck tube complete with a Shrader valve for inflation purposes. The long neck makes it easy to insert the bag into a gas main through a small hole drilled into the top of the main. This type of stopper is used predominantly for stopping off mains operated at pressures below 75Kpa and for larger diameter mains in excess of 300mm diameter.
