Pipe Penetration Seals
F2HR Firestop

The Pipeseal F-2HR provides a superior method for making a firestop penetration seal. With the F-2HR, you get a UL classified firestop seal with a two hour F-rating. The systems include metallic and PVC piping and copper tubing through concrete walls. The holes can be either core drilled or use pipe sleeves. (See systems C-AJ-1423, C-AJ-1424, and C-AJ-2369) You must determine which model and how many links will be needed for your penetration. Assistance can be provided, or the sizing program below can be used.
