Nylon plugs are the standard drain plugs for testing the leak-tightness of foul water lines at the time of installation.
Furthermore, the range of sizes makes 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.
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.
