ROCKWOOL Firepro Pipe Collars

A powder coated steel sleeve containing a flexible graphite based intumescent liner manufactured to suit the pipework to be fire stopped and designed for sealing UPVC, polypropylene, HDPE and ABS plastic pipes.

Integral toggles are opened up and the collar is simply fitted around the plastic pipe. The toggles are closed and the collar is pushed flush to the surface of the wall or underside of the floor. The collar is then securely fastened to the structure by means of fire resistant fixings threaded through fixing tabs. Under fire conditions the intumescent material swells filling the void left by the burnt out plastic.

Where fire protection is required from both sides of the wall, a pipe collar will be required each side of the wall.


  • Simple to install.
  • Water resistant.
  • Maintenance free.
  • Available to suit pipe sizes ranging from 55 to 355mm O.D.
  • Available from order in 48 hours.
