The PPM Nylon Expanding Pipe Stopper 6" (NES150) is an essential tool designed for temporarily sealing pipe ends or openings in various testing and blocking applications. Manufactured by PPM, these pipe stoppers are primarily used to block water, gases, and foreign objects in newly installed pipes or during repairs of existing pipe work systems. PPM offers a diverse range of pipe stoppers, available in multiple styles and sizes to suit a wide array of applications, with custom-made options also available for specific pressure testing requirements. This expanding pipe stopper operates with a central spindle/shaft fitted with two 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 seal within the pipe. Some models are also available with a hollow shaft, enabling connections for standard hoses or the use of fixed or free nipple caps. Nylon plugs, such as the NES150, are the standard choice for testing the leak tightness of foul water lines during installation. Their extensive range of sizes makes them suitable for numerous applications across the water, gas, and other industries where pipes are utilized or where openings need to be blocked.
