InterVac P-25 Flanged 90 Degree Elbow – PVC Exhaust Fitting (Old Part # P013)

The InterVac P-25 Flanged 90 Degree Elbow is a special PVC fitting that connects your central vacuum exhaust piping to an exterior wall or overboard exhaust system. You can use it with InterVac overboard exhaust setups or with the RMD unit. This fitting also works with any other central vacuum system and many general applications that use standard PVC fittings.

What is a Flanged 90 Degree Elbow and Why Do You Need One? Central vacuum systems push out hot air and fine dust through the exhaust. The P-25 elbow lets you make a smooth 90-degree turn and then mount the exhaust directly to an exterior wall. Therefore, you can safely vent the air outside instead of blowing it back into your garage, RV, or utility room. So you reduce heat buildup, keep allergens out of your living space, and create a cleaner, healthier environment.

How the P-25 Flanged Elbow Works

One side of the P-25 has a standard female PVC socket that accepts 2″ pipe. The other side features a square flange with mounting holes. You glue PVC pipe into the female side, then bolt or screw the flanged side to an exterior wall or your overboard exhaust setup. After installation, the elbow creates a secure, airtight connection that directs exhaust air outside.

Key Features of the InterVac P-25 Flanged Elbow

This fitting offers a smooth 90-degree sweep for good airflow and reduced turbulence. It includes a sturdy mounting flange with pre-drilled holes for easy attachment to walls. Plus, the durable white PVC construction resists heat and corrosion, making it ideal for both indoor and outdoor exhaust applications.

Who Uses the P-25 Flanged 90 Degree Elbow? Homeowners and RV owners use it when installing or upgrading overboard exhaust systems. It works perfectly with InterVac overboard exhaust funnels and the RMD unit. Because it is compatible with any central vacuum system, installers also use it for custom exhaust routing in garages, workshops, and non-InterVac setups.

Easy Installation and Compatibility

You can install the P-25 using standard PVC cement on the pipe side and screws or bolts on the flange side. It connects easily to 2″ PVC pipe and works with all central vacuum systems. Whether you are doing a replacement, adding an exhaust vent, or building a new system, this fitting provides a reliable solution.

Built for Everyday Reliability

InterVac makes this flanged elbow from high-grade PVC, so it withstands heat, vibration, and long-term use. Whether you vent your central vacuum outside your home, RV, or coach, the P-25 delivers a strong, leak-free connection that improves air quality and system performance.
