All plugs conform to British Standards BS8005 for low pressure testing and sealing of pipes.

The basic principle - effective sealing is simple, insert the plug into a pipe opening and tighten the wing nut clockwise. The rubber ring will expand and provide a positive seal. To remove simply reverse the process.

Tightening the wing nuts is easy with the Pipestoppers patented friction free washer.
