View partAP Products RV Compartment Door D-Seal & Foam Weatherstrip Guide
Compare adhesive D-profile and foam RV weatherstripping used around appropriate doors, storage compartments and windows. Unlike clip-on bulb seals, these profiles rely on a pressure-sensitive adhesive or specified mounting method. The numbers below identify actual AP Products rolls, not a universal fitment list for every cargo door.
Manufacturer profile drawings
For cross-section illustrations and original dimensional tables, see AP Products illustrated catalogs and the factory door/window seal listings. The profiles below are identified by their published nominal width, height and tape type; compare the dimensions and cross-section with your existing gasket before ordering.
Functional gasket-location guide
A D-bulb compresses against the mating panel or flange. Check the closing clearance and whether the original seal compresses vertically or sideways.
Identify the body-side versus door-side adhesive surface; hinges and latches must still engage fully after adding a seal.
Use a foam or ribbed strip only when the original gasket geometry and compression require that profile; not every ribbed strip is D-shaped.
HATS tape and white PSA tape are separately specified. Verify surface preparation, temperature and original door material with the manufacturer.

View partWhy similarly sized gaskets may not interchange
018-206 is a ribbed black 1 × 1-inch foam D seal with HATS tape; 018-023-PT is a black foam D seal of the same nominal width and height with white PSA tape; 018-1097 is the white HATS-tape variant. The manufacturer's adhesive, surface shape and material details must match the application. The smaller 018-204/018-224 profiles measure ½ × ⅜ inch, so they should not be used to fill a 1-inch original gasket space without evidence.
Entry-door seals are a different application
Lippert's entry-door inner-frame seal 2020218613 (supersedes 250947) is not confirmed interchangeable with any AP Products seal here, even if one dimension appears similar. For the factory Lippert door seal and hinge, see the entry-door hinge and seal guide.
This page covers adhesive and foam weatherstrips. For different clip-on bulb, double-bulb and J-bulb sections, see the door and window bulb-seal guide.
Installation caution: An incorrect gasket height can keep a baggage door from latching, deform hinges or prevent full sealing. Check the original closing clearance before replacing the entire perimeter, and do not seal required drains or vents.
