The AR41866 is the genuine flange assembly for Annovi Reverberi (AR) RRV-series pressure-washer pumps used on Hydro-Tek Hot-2-Go skids and machines. The flange is the mounting interface between the pump and the engine or motor, and a cracked, worn, or leaking flange is a common cause of pump misalignment, vibration, and oil seepage.
Built for the job
Installing the correct OEM flange restores proper pump-to-drive mounting and sealing, so the RRV pump runs true and delivers full pressure without the wobble or leaks that lead to premature seal wear.
Common uses
- Rebuild or repair an AR RRV-series pump on a Hot-2-Go unit
- Replace a cracked or worn flange causing vibration or misalignment
- Correct oil seepage traced to a damaged pump flange
- Keep a pressure-washer fleet in service with genuine AR parts
