Hose Inlet 003970133

The hose inlet (part# 003970133) is a genuine Lindhaus replacement for the fitting where the suction hose enters the machine body. This hose inlet forms the sealed connection between the hose and the internal airway, so its condition directly affects how much suction actually reaches the nozzle.

Because it is a shared component, the same fitting is used across a family of Lindhaus uprights and their Eco-Force variants. It takes the repeated push-and-pull of connecting the hose and the strain of the hose flexing during use, and over time the collar can crack, wear loose, or lose its seal, letting air leak in right at the entry point.

Replace the hose inlet if the hose no longer seats tightly, if you feel air drawing in around the connection, or if the fitting is cracked or worn. A fresh hose inlet restores a tight, sealed hose connection and full suction. For the matching hose, wands, and body parts, browse our genuine Lindhaus vacuum parts.
