Nullifire FP302 Intustrap

October 21, 2026

Plastic pipework passing through compartment walls and floors requires an appropriate firestopping solution. Nullifire FP302 Intustrap is an intumescent pipe wrap designed for use in specified systems to help maintain compartmentation when combustible pipes pass through a building element.


What is Nullifire FP302 Intustrap?

FP302 Intustrap is a flexible, graphite-impregnated intumescent pipe closure product supplied in roll form. It is designed to be installed around suitable pipes in accordance with the manufacturer's tested system details.


When exposed to fire, the intumescent material expands to help close the opening created as a combustible pipe softens or burns away.


Where is FP302 Intustrap used?

FP302 is used in approved configurations involving combustible pipes and compatible wall or floor consturctions. The required number of layers and installation arrangement depend on factors such as the pipe diameter and the tested system.


The manufacturer's technical documentation must be checked to confirm the correct installation for the specific application.
