Keep your RV central vacuum system connected and airtight. The Dirt Devil 5531-W inlet reducer bridges the gap between your vacuum hose and the inlet valve, stepping down from the 2-inch tubing side to the 1.66-inch inlet fitting -- no suction loss, no improvised tape-and-clamp workarounds.
Central vacuum systems are only as good as their connections. A loose or ill-fitting inlet reducer means lost suction at the wall valve -- exactly where you need pickup power most. The 5531-W is purpose-built for the Dirt Devil CV1500 RV Central Vacuum System, using a simple press-fit design that seats firmly into the inlet valve without complex locking hardware.
Made from high-grade PlastiFlex PVC, this reducer is rigid enough to hold its shape under repeated hose insertions and light enough not to stress the wall-mounted inlet plate. Pair it with the HP Products part 4865 mounting plate for a complete, code-correct inlet installation.
Seats firmly into the inlet valve opening without threading or locking mechanisms -- quick to install and easy to service.
Reduces the standard 2-inch vacuum tubing side to the 1.66-inch inlet valve port for a secure, suction-tight transition.
High-grade rigid PVC resists cracking and deformation through repeated use and normal RV vibration in transit.
Engineered specifically for the Dirt Devil CV1500 RV Central Vacuum System -- not a generic fitting adapted from residential stock.
The 5531-W is designed for use with the Dirt Devil CV1500 RV Central Vacuum System. It is intended to be used alongside the HP Products part 4865 mounting plate, which provides the wall-mount bracket and inlet valve housing. If you are replacing a worn or broken reducer in an existing CV1500 installation, the 5531-W is the correct OEM-spec replacement part.
The 5531-W attaches to the inlet valve using a press fit -- it does not lock in place. This is by design and matches the OEM specification for the CV1500 system. The fit should be snug enough to prevent suction loss during normal vacuuming operation.
