Nylon Pipestoppers - PipeStoppers - #2

To complete the Pipestoppers™ range of nylon expanding plugs we offer all sizes of aluminium plugs.

These are provided in sizes from 3" (75mm), for more arduous duties such as long immersion in water and higher temperature and are manufactured with ¹/₂", 1", 2" (12mm, 25mm, 50mm) outlets.

The standard seals are made from natural rubber and special rubber seals are available for chemical applications where greater resistance is required.

Acetal Washer

As can be seen from the sectioned view, the unique assembly of the central waterway into the base plate via a snap taper fit and "0" ring seal provides a positive water and air tight joint. The provision of a friction reducing acetal copolymer thrust washer inserted between the wing nut and top plate facilitates easy expansion and release.

Sizes available are for pipe bore sizes.

These plugs conform to ISO Standards for low pressure testing and sealing of pipes.

Notes:

(1) They are slightly less efficient at the extreme higher limits of expansion than in the middle and lower ranges.

Available as cylindrical, spherical or rectangular stoppers for use when breaking into existing lines for repairs, maintenance and new sections.

These are especially useful where entrance and exit apertures are difficult to access with solid plugs.

(2) Pressure testing depends upon the cleanliness and condition of the pipe bore.

(3) Nitrile, Silicone and Viton rubber seals to resist different chemicals and higher temperatures are available from stock as accessories.

(4) Operators using air or other gases to make leak tests must take the appropriate precautions.

Each stopper is available in 1" (25 mm) sizes from 2" (50 mm) up to 82" (2m) as standard and larger to special order.
