When your RV slide out needs a fresh seal, the buying decision usually comes down to part-number matching and total cost. Two kits pair the same two components: an 018-312-EKD D seal and an 018-341 EK base seal. Both are black and marketed for RV camper slideout systems. The Combo RV Slide Out Seal is listed at USD 63.99, while the Black RV Slide Out Seal is listed at USD 85.99. That USD 22.00 spread is the main practical difference between otherwise similar kits.
Quick verdict
If you want the same part-numbered seal pair for the lower listed price, the Combo RV Slide Out Seal is the easy call. The Black RV Slide Out Seal makes sense only if you want the color spelled out in the product name and are comfortable paying the higher price.
Comparison at a glance
| Product | Listed price | Price bar |
|---|---|---|
| Combo RV Slide Out Seal 018-312-EKD \& 018-341 EK For RV Camper Slideout System | USD 63.99 | |
| Black RV Slide Out Seal 018-312-EKD \& 018-341 EK for RV Camper Slideout System | USD 85.99 |
Both kits share the same 018-341 EK base-seal dimension of 1/2" x 2.75" x 35', the same black color, and the same new condition. The 018-312-EKD D seal is part of both combos, and the installation approach described for each is identical: slide the D seal onto the EK base and screw the rubber into place.
Where each product wins
- Combo RV Slide Out Seal: wins on listed price. You get the identical two-component setup for less.
- Black RV Slide Out Seal: wins on title clarity. The name states the color directly, so there's no question about the finish from the title alone.
Product notes
Combo RV Slide Out Seal 018-312-EKD \& 018-341 EK For RV Camper Slideout System
The Combo kit brings the 018-312-EKD and 018-341 EK seals together in one listing at the lower listed price. The description walks through the installation approach: slide the 018-312-EKD D seal onto the EK seal base and screw the rubber into place, with the D seal designed to slide onto base tracks easily. If you're maintaining an RV slideout and want both components without paying more than necessary, this is the version to choose. The main limitation is that the finish is not stated in the product title. If a title that names the color matters for your order review, the other listing makes that explicit for a higher price.
Black RV Slide Out Seal 018-312-EKD \& 018-341 EK for RV Camper Slideout System
This kit is the higher-priced option, and the title makes the color part of the purchase decision upfront. Behind the name, it carries the same 018-312-EKD and 018-341 EK components, the same finish, and the same new condition as the Combo listing. The description follows the same installation sequence: slide the D seal onto the EK base and secure it with screws. Choose this one when having "Black" in the product name matters for your records. The limitation is the price gap: you pay more for the same part numbers and finish, so the extra cost is tied to the clearer title rather than additional components.
Final choice by use case
For most buyers replacing a slide out seal with these part numbers, the Combo RV Slide Out Seal gives you the same described components and color for less money. If you specifically want the product title to say "Black" and don't mind spending more for that clarity, the Black RV Slide Out Seal is the one to pick. The two kits are nearly identical in their listed details, so the listed price and title clarity are what separate them.
