Pipe collars are manufactured from a high performance material bonded inside a steel sleeve, which on exposure to heat from a fire will rapidly expand inwards to squeeze the collapsing plastic pipe until the aperture is completely sealed.
Pipe collars are tested in accordance with the performance requirements of BS476: Part 20: 1987 and EN1366-3.
