Our intumescent pipe collars are manufactured from a high performance material bonded to the inside of a steel sleeve.
On exposure to heat from a fire they 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.

The pipe collars are light and compact, easy to install, maintenance free and find uses in multi- storey office buildings, flat level developments, hospitals and hotels.
Suitable for use and anywhere plastic soil and waste pipes pass through fire compartment walls and floors.
Also tested to EN1366-3, NHBC Type Approval.
