Steel pipe plug
1.5" (37 mm) PipeStoppers

Single steel plugs

In addition to the ranges of Nylon and Aluminium plugs and Inflatable Stoppers, the Pipestoppers Division of Huntingdon Fusion Techniques Limited, also manufactures a range of Steel plugs from 2" to 72" in diameter.
These plugs are typically suitable for more arduous duties such as long immersion in water and use at higher temperatures or for contact with acidic or alkaline environments for which the Nylon and Aluminium plugs might be unsuitable.
The plugs are merely inserted into the pipe and the wing nut tightened to force the top and bottom plates together, thereby expanding the rubber ring to seal tightly in the pipe. The patented Friction Free washer enables easy tightening of the wing nuts.

The Steel Plugs are manufactured with 1/2", 1" & 2" outlets.

1/2" outlet for plugs up to 6" ,

1" outlet for diameters 8" to 18" and

2" outlet for 20" and greater diameters.

The standard seals are made from natural rubber although special rubber seals are available for applications which may need a greater chemical resistance and/or higher temperature tolerances.
(alternative rubber rings options are: Silicone, Nitrile & Viton)

All plugs conform to British Standards BS 8005 for low pressure testing and sealing of pipes.
