FP302 Intustrap is a rubber based product with graphite impregnation, designed to close off combustible elements whilst maintaining compartmentation. FP302 is also a component product incorporated within many Nullifire fire stopping products.

Fire Rating: 240 Minutes


FP302 is a tested and proven closer device to be used around combustible pipes, insulated non-combustible pipes, and conduits (filled or empty). FP302 is suited to a range of combustible elements, up to a maximum diameter of 160 mm in floors, and 110 mm in walls.
FP302 is required to be restrained within a suitably tested substrate or included within other Nullifire tested system solutions. These include but are not limited to : Rigid Walls and Floors, FB750 Intubatt and FR230 Intucompound.
Always refer to the relevant and correct Nullifire Application Sheet, to ensure compliance with tested methodology.

Always read SDS, pre-application guidance and relevant application detail prior to application. Ensure the latest documents are downloaded prior to every project commencement.

Individual rolls of FP302 must be separated by a release paper when stacked unpackaged.
FP302 is tested with inspection in mind. The product should protrude from all substrates by a maximum of 10 mm. This enables easy inspection.
FP302 may also be installed anywhere within the floor slab, up to 300 mm from the underside of the soffit. We recommend installation is either at the top or the bottom face to prevent destructive inspection requirements.
FP302 should be installed symmetrically in flexible wall systems, within FB750 Intubatt.
Do not use around CPVC pipes; for this specific application, please use FS719 HP Blue for CPVC.
If used around Pegler X-Press Carbon steel pipes, the pipe manufacturer should be consulted and their recommendations followed.
When using FR230, if the service type requires thermal expansion, FP302 should be the full depth of the FR230 primary seal if an alternative thermal accommodation joint has not been used.
The product is tested with or without the release tape in position, so it can be used with or without the tape present.
