H-P Products Metal Fire Wal...

Product details
Part 7465 is a metal sleeve, 2 inches outer diameter and 6 inches long, sized for central vacuum pipe passing through a fire-rated wall. Where code requires a non-combustible pathway at a fire barrier penetration, this tube is the fitting installed in the framing opening before the vacuum pipe is run through it, keeping the penetration itself compliant with the rated assembly.
It is a standard-size fitting for 2-inch central vacuum pipe rather than a part built to one manufacturer's system, so it suits H-P Products installations and other central vacuum lines built on the same 2-inch pipe. Confirm your local code requirements and the wall's rated assembly with whoever is inspecting the work, since fire-stop details and acceptable methods vary by jurisdiction.
Plan on one of these sleeves at each point a run crosses a fire-rated partition, whether you are roughing in a new whole-home system or extending an existing installation into a previously unpiped area of the house. The tube sits inside the framing opening and the vacuum pipe threads through its center, so it does not change how the system performs, only how that fire-rated penetration is protected against the spread of fire.
- Part: 7465
- Outer diameter: 2 inches
- Length: 6 inches
- Material: metal, for fire-rated wall penetrations
Keep this on the materials list any time a central vacuum run is planned across a garage wall, a mechanical room partition, or any other assembly with a fire rating attached to it. It is easy to overlook during a rough-in, and adding it after the wall is closed up is far more work than including it while the framing is still open.
