The PPM Nylon Expanding Pipe Stopper 2.5" (NES63) is an essential and versatile tool designed for temporarily sealing pipe ends or openings in various testing and blocking applications. These robust drain plugs are primarily used to seal off water, gases, and foreign objects in newly installed pipes or during repairs of existing pipework systems. PPM offers a diverse range of pipe stoppers, available in multiple styles and sizes, with custom options available upon request for specific pressure testing requirements. This particular stopper, the NES63, is a standard nylon plug, specifically engineered for testing the leak tightness of foul water lines during installation. Its extensive range of sizes makes these plugs ideal for a number of other applications in the water and gas industries, as well as in all other industries where pipes are used or where holes need to be blocked. All PPM Nylon Expanding Pipe Stoppers conform to British Standards BS8005 for low pressure testing and sealing of pipes. The design of the pipe stopper features a central spindle/shaft on which two plates are fitted, 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. These stoppers can also be supplied with a hollow shaft version for screwing on standard hose connections or for using fixed or free nipple caps.
