Expanding Pipe Stoppers - Nylon
Nylon plugs - 11/2 - 6" (38 mm - 150 mm)
Nylon plugs are the standard drain plugs for testing leak tightness of foul water lines at the time of installation. Furthermore, the range of sizes make these plugs ideal for a number of other applications in the water and gas industries as well as applications in all other industries where pipes are used or where there are holes to be blocked.
Pipe stoppers (or drain plugs) are used to temporarily seal the end of a pipe or opening for many different testing applications. Pipe stoppers are mainly used to seal off from water, gases and foreign objects in newly laid pipes, or pipework systems that are under repair.
PPM's range of pipe stoppers is available in a number of different styles to suit many applications for pipe sizes from 11⁄2 - 72" (38 mm - 1,829 mm). Special pipe stoppers are also available for pressure testing.
How it works?
The pipe stopper consists of a central spindle/shaft on which two plates are fitted with a natural rubber tyre (ring) between them. A wing nut on the shaft moves the two plates together, compressing the tyre and making the seal in 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.
Expandable pipe stoppers are available in three different types.
