Expanding Aluminium Pipe Stopper x 11″ [274 – 328mm]

Expandable test plugs for purging and general pipe blocking 

Pipe stoppers, or drain plugs as they are sometimes known, 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.

The range of Pipe stoppers are available in a number of different styles to suit many applications for pipe sizes from ½” to 72”. Special Pipestoppers are also available for pressure testing.

Sizes up to 72″ [1828mm]

How it works: 

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 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.

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.

Expandable Plugs are also available in Nylon and Steel

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


A carriage charge is applied to orders, for standard 1-2 day shipments to mainland destinations within the United Kingdom. Other destinations and premium services are available but subject to additional freight charges.
