From approximately 1935 to 1957, Airfloat produced beautiful trailers that are highly collectable today. Their most unique identifying feature is their fixed porthole windows.  

To re-seal your windows, you'll need this silicone rubber gasket.  This gasket goes around the round opening's metal flange and then around the edge of your round piece of glass.  It is generally concealed from the outside by a wide black metal ring that goes around the window on the exterior of the trailer. 

You'll receive approximately 4 feet of gasket, which is enough to reset one window.  You will trim to the precise length.

Made of black silicone rubber. Silicone rubber does not shrink or crack with age.  However, do not stretch it while installing because it has a long memory and will retract as it settles in, leaving a gap.  If you would like to use a little adhesive, we recommend black or clear silicone sealant (like 100% silicone caulk).  Silicone caulk makes a good adhesive for silicone rubber to both glass and to itself.
