RANGE: 1.5 - 24" / 40 - 600 mm
To complement the range of nylon expanding plugs, we offer all sizes of aluminium plugs.
These are provided in sizes from 1.5″ / 40 mm upwards and are suitable for more heavy-duty applications, heat-resistant up to 90ºC (194ºF). These plugs are typically used for general sealing of pipes and purging.
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.
