Product Description:

In order to obtain effective Fire Prevention it is necessary to consider the actual penetrations through fire compartment walls and floors. Synthetic pipes should be especially considered as they are a transporter of fire and smoke from one compartment to another.

The Firestem™ Pipe Collar consists of a one part system, 1.5mm thick and closed by use of a toggle clip. The shells are lined with a new generation intumescent impervious to water.

One side of the collar has 4 mounting lugs with four holes of 7mm diameter for fixing by means of metal expanding (or through) bolts 6mm diameter.


PVC and PE starts to soften at about 115°C, consequently in a short period of time an opening will develop in a fire compartment wall or floor allowing flames and smoke to breach it.

The Firestem™ Intumescent Collar counteracts this and at around 140°C the Firestem™ Flex starts to react under the influence of heat, expanding to seal off the pipe thereby stopping the spread of smoke and fire.
