How it works

A central spindle/shaft on which two plates are fitted with a natural rubber tire (ring) between them, a wing nut on the shaft moving the two plates together compressing the tire 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.

Aluminium Plugs – 11/2 – 36″ (40 mm – 900 mm)

To complement the range of nylon expanding plugs, we offer all sizes of Aluminium
plugs. These are provided in sizes from 11/2″ upwards and are suitable for more arduous
duties such as i mmersion in chemicals and/or higher temperatures.

Nylon Plugs – 11/2 – 6″ (38 mm – 150 mm)

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.

Steel Plugs – 11/2 – 36″ (40 mm – 900 mm)

PPM Pipe Purge System also manufactures a range of Steel plugs from 11/2 – 72″ in

immersion in water and use at higher temperatures or contact with acidic or alkaline
environments for which the Nylon and Aluminium plugs may be unsuitable.
