MetraSeal WALKER

The wall penetration seal that keeps its seal and stays in place when pipes move due to thermal expansion and contraction

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 wall penetration seal.

A wall penetration seal that stays right where you put it...
The MetraSeal WALKER is the wall penetration seal/mechanical seal for pipes that move. Creating a snug, water-tight seal, the unique design permits unlimited axial pipe movement, while at the same time keeping the MetraSeal WALKER wall penetration seal properly positioned in the hole. When pipes move axially, you know the fire stop is right where it was installed.

Instantly verifiable
The MetraSeal WALKER is a fast, permanent, seal made of interlocking links, filling the gap with an instantly verifiable thickness around any metallic, steel or copper tubing.

The MetraSeal WALKER can be used anywhere a round piping penetrates a round hole in floors and ceilings, as well as foundations, and works 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.
