Fire Collar 50mm 4 hour 

4 hour fire rated stainless steel pipe collar is suitable for fitting to concrete, masonry, porous concrete or stud wall constructions.

It has been designed to intumesce (rapidly expand) inwards during the event of a fire, squeezing the pipe and sealing the resulting gap, which prevents the spread of fire throughout a building.
