Expanding Pipe Stoppers

Expanding Pipe Stoppers

Sizes: up to 72” (1828 mm)

Pipe stoppers 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.

GBC’s range of Pipe stoppers are available in a number of different styles to suit many
applications for pipe sizes from 1/2” to 72”. Special Pipestoppers are also available for
pressure testing.

Nylon Plugs

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.

Aluminium Plugs

To complement the range of nylon expanding plugs, we offer all sizes of aluminium plugs. These are provided in sizes from 1.5” upwards and are suitable for more arduous duties such as immersion in chemicals and/or higher temperatures.

Steel Plugs

GBC also offer a range of Steel plugs from 2” to 72” in diameter. These plugs are typically suitable for more arduous duties such as long immersion in water and use at higher temperatures or for contact with acidic or alkaline environments for which the Nylon and Aluminium plugs may be unsuitable.

All plugs conform to British standards BS8005 for low pressure testing and sealing of pipes.
