Nylon Expanding Pipe Stopper (Through Bore) 4″

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 Pipe stoppers are also available for pressure testing.

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, nylon, aluminium and steel.

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 as well as applications in all other industries where pipes are used or where there are holes to be blocked.

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.
