The PPM Nylon Expanding Pipe Stopper 4" (Model NES100) is an essential tool designed for temporarily sealing pipe ends or openings in various testing and blocking applications. Manufactured by PPM, this stopper is 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 upon request for specific pressure testing requirements. This particular Nylon Expanding Pipe Stopper is the standard choice for testing the leak tightness of foul water lines during installation. Its robust design features 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 seal within the pipe. Some stoppers are also available with a hollow shaft, enabling connections for standard hoses or the use of fixed or free nipple caps. With an extensive range of sizes (1.5" - 6" / 38 - 150 mm), these plugs are ideal for numerous applications across the water, gas, and other industries where pipes are utilized or where openings need to be blocked. All PPM Nylon Expanding Pipe Stoppers conform to British Standards BS8005 for low pressure testing and sealing of pipes.
