The COUPLING ELEMENT RV PUMP is a rubber replacement part made for Edwards RV3 and RV5 rotary vane pumps This small rubber piece sits between the motor coupling and the pump coupling. Its job is to transfer power from the motor to the pump while soaking up vibration and shock. If your RV pump is noisy or shaking too much, this part is likely worn out.
