Welding Purge Plug


PlugCo offers a range of shapes and sizes of welding purge, suitable for all applications. Made from a natural rubber bladder covered in waterproof polyurethane coated nylon to prevent friction and static electricity build up.

There are six different types available:

  • Cylindrical – These are generally used for blocking pipes where Access is restricted.
  • Spherical – These purge have less contact area than cylindrical purges, and are most suited to applications where access is further limited. Due to its shape the spherical welding purge can be used at any angle.
  • Square / Rectangular – These purges have a variety of applications, including in air conditioning ducting and venting.
  • Doughnut – These purges require minimal space and are perfectly suited to larger diameter pipes as there is less inflation required.
  • Sausage – The design of this type gives more contact area between the purge and the pipe wall enabling these purges to hold back more pressure.
  • Heat Resistant – These purges are made from a specially designed kevlar and nomex mix material to withstand temperatures up to 500ºC for applications involving higher temperatures such as pre heating

Each weldng purges comes with an inflation hose fitted with a schraeder valve enabling inflation with a standard airline, bicycle or foot pump.
