AP 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.

Why 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.
