AP Products EK/EKD Slide-Out Seal Bases, D Seals & Wipers
Identify the correct AP Products EK and EKD slide-out seal components by the actual part number, wiper length, D-bulb profile and mounting method. EK wiper bases, double EKD bases, slide-on D seals and separate channels have different functions. Two parts with EK/EKD in their descriptions are not automatically a matched pair.
Manufacturer seal-profile illustrations and numbered catalog
Consult AP Products' current illustrated service catalog and the original manufacturer slide-out seal listings for factory cross sections, colours and published dimensions. Compare the illustrated seal profiles and original dimensions before choosing a replacement.
Slide-out seal components — choose the profile first
Combines a mounting base with a flexible wiper blade; the wiper must reach the proper moving surface without binding
A taller double-profile base with specific grooves and wiper dimensions; not interchangeable with a narrow EK base
Separate compressible bulb that fits a designated receiving track; exact groove compatibility must be verified
Supporting profile or wiping component; these do not replace a base, gasket and fasteners automatically

Compatibility and measurement checklist
Inspect a clean, undamaged cross section of the existing seal. Note mounting surface, HATS tape or other attachment, the receiving channel, wiper projection, bulb compression gap and total linear length. Factory dimensions are nominal and must be compared to the original. The black and white 018-316 / 018-317 bases share a maker-listed profile, but different installations may require a particular finish. For D seals, confirm track geometry instead of assuming that any D-seal fits any EKD base.
Check the seal profile and roll length
018-314 is a white slide-out rubber seal with wiper, nominally 5/8 × 1-15/16 inches in a 35-foot roll. 018-3203 is a black bulb seal with a 2-1/8-inch wiper; AP Products lists a 35-foot roll. 018-338-BLK is a black slide-in secondary seal, 13/16 × 11/16 inches in a 30-foot roll. These profiles attach and seal differently. Match the original cross-section, retaining track and required roll length before ordering.
