►HOW IT WORKS

The pipe stopper consists of a central spindle/shaft on which two plates are fitted with a natural rubber tyre (ring) between them.

A wing nut on the shaft moves 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.
