Nylon Expanding Plugs

nylon expandingThis line of low cost expanding pipe testing and stopping plugs provides the following features:

  • manufactured from nylon, an engineering polymer
  • resistant to salt water corrosion
  • resistant to many chemicals
  • gives a high quality leak tight seal in the selected orifice

There are two types:

  • a solid shaft version with five sizes from 0.5 inch up to 1.5 inch; and,
  • a hollow shaft version with eleven sizes from 0.5 inch to 6 inch inclusive.

All plugs have:

  • a central spindle/shaft on which two plates are fitted with a natural rubber tyre/ring between them
  • a wing nut on the shaft moving the two plates together compressing the tire and making the seal in the pipe or orifice
  • natural rubber tires which can be substituted for different rubbers where additional chemical resistance is required

The hollow shaft version with sizes from 0.5 inch to 6 inches allows:

  • water or gas to be injected or drained as required
  • sizes of 1.5 inch and above are threaded with a half inch BSP for the connection of standard nuts/hose fittings
  • is provided with a solid end cap seal
  • are fully demountable for cleaning and parts replacement
  • Optional end caps are available with fixed nipples/nozzles for hose connection or free nipples which can rotate when heavier hoses are used.

Where required, we can provide customers with end caps with their logo or company name moulded on and we can provide them with their own special colours as well if desirable.

Plugs have been tested for pressure ratings as per chart below.
