Nylon pipe plug
12.5 mm - 150 mm (0.5" - 6") PipeStoppers

NYLON PLUGS from 0.5" (12mm) through to 6" (150mm)
Pipestoppers™ Nylon plugs are used internationally as 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.
Testing and sealing of all pipes, pipe joints and pipe work assemblies can be done with the Pipestoppers plugs. They can be supplied with a hollow shaft version for screwing on standard hose connections or for using our own fixed nipple caps or the free nipple and cap assemblies that we manufacture.

Or for the smaller sizes, they can be supplied with solid shafts for greater pressure testing capabilities.
Other applications include: Sealing holes in castings, tanks, other assemblies for spraying and blasting to protect the insides. Maintenance and installation of swimming pool and water spa pipework.

Nylon 6 is an engineered polymer which is resistant to salt water corrosion it is also resistant to many other chemicals. Along with natural rubber rings they provide a high quality leak tight seal in the selected orifice.
There are two types:

- A solid shaft version with five sizes from 0.5" (12mm) up to 1.5" (38mm) and
- A hollow shaft version with eleven sizes from 0.5" to 6" inclusive.

All plugs have:
A central spindle/shaft on which two plates are fitted with a natural rubber tyre (ring) between them, a wing nut on the shaft moving the two plates together compressing the tire and making the seal in the pipe or orifice. Natural rubber tyres which can be substituted for different rubbers where additional chemical and/or heat resistance is required. Alternative rubber rings options are: Silicone, Nitrile & Viton)

The hollow shaft version with sizes from 0.5 inch to 6 inches allows:
