This is a good door gasket to use on almost all 1957 to 1962 and 1964 Airstreams.  It works on most Airstreams from 1957 to 1962 for both the main door seal and the inner "door within a door" (if present) when the door edge overlays the exterior trailer wall.  It does not work in situations where the door edge is flush inset into the trailer exterior.  On 1964 Airstreams, it works on the main door only, but not the inner door because the inner door is flush inset.  It does not work on most 1963 Airstreams at all because both your main door and your door within a door are flush inset.

To work on the main door, your door edges must overlap the trailer sides rather than close flush inset with the trailer side. It is installed in up to three locations, each requiring the purchase of a separate length of gasket:

First - The most important location is installed around the perimeter of the door, itself.  When the door closes, it compresses against the exterior shiny trailer skin.

Second - It is installed on the flange on the door's jamb.  When the door is closed, this gasket compresses against the inside skin of the door. This creates a double seal or a backup seal for the first gasket described.  It is not absolutely necessary, but it was original to Airstream trailers of the era and is your insurance against leaks around the outer gasket. 

Third - On trailers with an overlay-style "door within a door" it is used on the inner door too. It is used once for this "door within a door."

Always attach the gasket to the mounting flange with the gasket's flap-like protrusion pointing to the outside edge of the mounting flange.

Please contact us before ordering if you are unsure about installation or whether this fits your trailer.

NOTE: If your door or hinges have been bent over the years, installing a new gasket may not fully stop your leaks. Or in some extreme cases, the new gasket can prevent the door from closing correctly.  Please inspect the gap between the door flange and trailer skin to make sure it is consistent all the way around.  If it is not, you may have to adjust your hinges or door curvature by re-bending them.
