MetraSeal 120 Firewalker

The fire stop for pipes in motion

Reality check – caulk just can't handle the pipes thermal expansion and contraction. The constant movement will pull and tear, compromising the integrity of the fire stop. And that means safety is compromised as well.

A fire stop that stays right where you put it...
The MetraSeal 120 FIREWALKER is the fire stop for pipes that move. Creating a snug, fire-tight, water-tight seal, the unique design permits unlimited axial pipe movement, while at the same time keeping the fire stop properly positioned in the hole. When there is a fire, you know the fire stop is right where it was installed, providing valuable time to protect life and property.

Instantly verifiable
The MetraSeal 120 FIREWALKER is a fast, permanent, intumescent, mechanical seal made of interlocking links that works as a fire stop, filling the gap with an instantly verifiable thickness around any metallic, steel or copper tubing.

UL listed with up to a 2-hour fire-protection rating it has an intumescent formulation which forms a hard, crust-like barrier when exposed to fire.

The MetraSeal 120 can be used anywhere a round piping penetrates a round hole in floors and ceilings, as well as foundations, andÊworks in core-drilled applications, as well as with pre-cast sleeves.

Quick, snug, permanent
A quick-to-install, snug, permanent rubber seal, it takes minutes to install around electrical conduit and other round pipe, including steel, cast iron and copper. It installs fast, saving time and money. And no drying or curing time is needed, so it instantly meets code. For sizes and selection chart and other our other seal products, click here.
