The PPM Nylon Expanding Pipe Stopper NES50 is an essential tool designed for temporarily sealing pipe ends or openings in various testing and blocking applications. These pipe stoppers are primarily used to prevent the ingress or egress of water, gases, and foreign objects in newly installed pipes or during the repair of existing pipe work systems. PPM offers a comprehensive range of pipe stoppers, with the Nylon Expanding Pipe Stopper being a standard choice for testing the leak tightness of foul water lines during installation. Its versatile design makes it suitable for numerous applications across the water, gas, and other industries where pipes are utilized or where openings need to be blocked. The mechanism of the pipe stopper involves a central spindle/shaft with two fitted plates, sandwiching a natural rubber tyre (ring). A wing nut on the shaft allows for the compression of these plates, which in turn expands the rubber tyre to create a secure and effective seal within the pipe. Some models, including certain Nylon Expanding Pipe Stoppers, can also be supplied with a hollow shaft, enabling connections for standard hoses or the use of fixed or free nipple caps.
