Fresh Air Outlet Hose

OE Match fresh air outlet hose for Porsche 356 models, designed to replace the original rubber sleeve located beneath the dashboard within the passenger compartment.

Fits:

• Porsche 356B 1959-63
• Porsche 356C 1963-65

Diagram ref no 39

The hose connects the fresh-air flap control box to the passenger compartment ventilation system, helping direct incoming air through the correct ventilation outlet. Porsche parts documentation identifies separate left and right versions, with one required for each side.

What Does the Fresh Air Outlet Hose Do?

The outlet hose forms part of the Porsche 356 fresh-air ventilation system. It provides the flexible connection between the flap control box and the passenger compartment air duct, allowing fresh air to be directed into the cabin.

The left and right hoses are handed components rather than identical universal pieces. Porsche documentation specifies 64457269106 for the left side and 64457269206 for the right.

Why Do Fresh Air Hoses Fail?

After decades of service, the original rubber components can deteriorate through age and environmental exposure.

Typical problems include:

Hardened or brittle rubber Cracking and splitting Loss of flexibility Poor sealing at the connections Distortion or deterioration Damage during dashboard or ventilation repairs

Deteriorated hoses can allow air to escape behind the dashboard instead of being properly directed into the passenger compartment.

When Should They Be Replaced?

Replacement is recommended when the hose is cracked, perished, damaged or no longer fits securely.

The hoses are also worth inspecting during dashboard restoration or refurbishment of the fresh-air and ventilation system, particularly where original rubber components remain fitted.
