When your RV slideout starts letting in drafts, moisture, or road noise, the seal between the slideout and the coach wall is usually the culprit. Replacing that seal is a straightforward project, but you have to pick the right profile and base. The New For RV Camper Slideout System RV Slide Out Seal 018-312-EKD 018-341 EK US combines a D-seal with an EK base so you can rebuild the sealing surface without replacing the entire slideout system.
Quick Verdict
If you need a black rubber D-seal with a matching EK base and are comfortable with the listed 35-foot lengths, this kit is a practical choice. The tough rubber construction is designed to handle weather and corrosion, and the easy-install design makes it a candidate for a weekend DIY job.
Who It Suits
This is a good fit for RV owners who already have an EK-style slideout seal base or those who want a complete two-piece replacement set for the slideout perimeter. The dimensions-1" x 15/16" x 35' for the D seal and 1/2" x 2.75" x 35' for the base-mean you'll want to measure your current seal and slideout opening before ordering.
What Stands Out
The description highlights that the D seal slides onto the EK seal base and screws into place, which should make installation more manageable. The rubber material is said to resist corrosion and extreme weather, which matters for an exterior seal. It also blocks rain, snow, dust, dirt, and noise, and the easier cleaning and longer life are practical benefits for any camper van owner.
Meaningful Trade-Offs
The main trade-off is that this kit is sold as a specific size: 35-foot lengths for both pieces. If your slideout needs a different length or a different seal profile, this won't be a universal fit. Also, there is no information about compatibility with specific RV brands or slideout mechanisms, so you need to measure carefully. The listed price is $53.99, and you should confirm that the dimensions match your existing setup before purchasing.
Bottom Line
If the 35-foot lengths and EK base style fit your RV, the 018-312-EKD D seal paired with the 018-341 EK base offers a durable, weather-resistant sealing solution at a clear price point. Just check your current seal base style and slideout measurements to avoid a mismatched kit.
