Nullifire FS709 HP Graphite Intumescent Sealant

October 20, 2026

Service penetrations can create potential routes for fire to spread through compartment walls and floors. Choosing the correct firestopping system helps maintain the intended compartmentation of a building.

Nullifire FS709 HP is a high-expansion graphite intumescent sealant designed for suitable firestopping applications.

How does Nullifire FS709 HP work?

Intumescent materials expand when exposed to high temperatures. In a suitable tested system, this expansion helps close openings around certain services as they are affected by fire.

FS709 HP is designed for specified penetrations involving combustible services and other approved configurations. The product can be used in a range of tested arrangements, including compatible FB750 Intubatt and FR230 Intucompound systems where the technical details permit.

Why choose the correct intumescent sealant?

Different services and construction types require different firestopping details. The type of pipe or cable, opening dimensions, substrate and required fire resistance must all be considered.

FS709 HP is not a universal replacement for every pipe collar, wrap or sealant. Always confirm that the specific installation is covered by the manufacturer's technical documentation.
