InterVac P-28 90 Degree Close Elbow – Black PVC Fitting for VacPort & Central Vacuum Pipe

The InterVac P-28 90 Degree Close Elbow is a compact black PVC fitting that creates a tight 90-degree turn in your central vacuum piping. You can use it with the InterVac VacPort or other central vacuum accessories. This fitting is especially useful when you want to install a VacPort inside a standard 2×4 studded wall. It also works with many other central vacuum systems for tight pipe routing.

What is a Close 90 Degree Elbow and Why Do You Need One? Most 90-degree elbows have a long sweep that takes up more space. The P-28 is a “close” elbow, so it makes a much tighter turn. Therefore, you can install a VacPort (wall inlet) directly into a 2×4 stud wall without the pipe sticking out too far. So you get a clean, flush installation and save valuable space in walls, closets, or tight areas.

How the P-28 90 Degree Elbow Works You glue one end of the P-28 to your central vacuum pipe and the other end to your VacPort or another fitting. After installation, the tight 90-degree angle allows the VacPort to sit almost flush with the wall surface. Because it is compact, it fits easily inside standard 2×4 stud cavities where a regular elbow would not.

Key Features of the InterVac P-28 Close Elbow This fitting features a short-radius 90-degree design in durable black PVC. It provides a strong, airtight connection while saving space. Plus, the smooth interior helps maintain good airflow even with the tighter turn.

Who Uses the P-28 90 Degree Elbow? Installers use it when mounting VacPorts in 2×4 walls or when routing pipe in tight spaces. Homeowners and RV owners also choose it for repairs or upgrades. Because it works with many central vacuum accessories and systems, it is a versatile fitting for both InterVac and non-InterVac setups.

Easy Installation and Compatibility You can install the P-28 using standard PVC cement. It connects easily to 2″ central vacuum pipe and VacPorts. InterVac designs this close elbow for tight installations, so you can achieve a professional, space-saving result whether you are doing a new build or a replacement.

Built for Everyday Reliability InterVac makes this fitting from tough black PVC, so it withstands years of use without cracking or leaking. Whether you install a VacPort in a stud wall or use it for other tight pipe turns, the P-28 delivers a reliable and compact solution for your central vacuum system.
