Replacing the rubber seal around your RV slideout usually starts with a part-number hunt. The confusing moment comes when two replacement kits show up with the same 018-312-EKD and 018-341 EK references, both in black, both described as new, and both following the same two-piece install path-yet they sit at different prices. That is the choice you need to make: the Black RV Slide Out Seal or the 2 In 1 RV Slide Out Seal. This head-to-head looks at what each kit offers and which one makes sense for your camper.
Quick verdict
Both kits are built around the same two-part idea: the 018-312-EKD D seal slides onto the 018-341 EK base, and the rubber is screwed into place. The after-sales choice is the same, too-money back or replacement at the buyer's option. The real differences are the price and the product name. If you already know these part numbers fit your slideout, the lower-priced Black kit is the default pick. Choose the 2-in-1 kit when the name itself makes the two-piece layout easier for you to recognize.
Comparison table
At a glance, the two kits match on part references and color, but the prices sit at different points.
| Product | Price | Price bar |
|---|---|---|
| Black RV Slide Out Seal 018-312-EKD & 018-341 EK for RV Camper Slideout System | $63.99 | |
| For Rv Camper Slideout System 2 In 1 Rv Slide Out Seal 018-312-Ekd & 018-341 Ek | $85.99 |
Where each product wins
Where the Black kit wins: price. It is the lower-cost entry point and it still uses the same 018-312-EKD and 018-341 EK references as the pricier kit. You are not sacrificing part matching to save money.
Where the 2-in-1 kit wins: name clarity. The '2 In 1' wording tells you before opening the package that both pieces are included, and that can be enough for a quick ordering decision.
Product notes
Black RV Slide Out Seal 018-312-EKD & 018-341 EK
The Black RV Slide Out Seal kit is the cost-conscious pick in this head-to-head. It pairs the 018-312-EKD D seal with the 018-341 EK base and uses the same install routine as the pricier kit: slide the D seal onto the EK base, then screw the rubber into place. The catch is in the product name: it does not include the '2 In 1' wording, so if that phrase is how you identify the two-piece kit, you may need to match part numbers instead. For shoppers focused on replacing the slideout seal without paying extra, this is the one to grab.
2 In 1 RV Slide Out Seal 018-312-EKD & 018-341 EK
The 2 In 1 RV Slide Out Seal kit is the easier one to recognize by name, with '2 In 1' right in the title. At $85.99, however, it is the more expensive way to get the same 018-312-EKD and 018-341 EK combination and the same black color. The install steps still call for sliding the D seal onto the EK base and screwing the rubber into place. Its limitation is the extra cost relative to the Black kit; you pay $22 more even though the part numbers and seal configuration described in both kits are the same. If you want the clearer name, this option works, but it costs more for the same replacement job.
Final choice by use case
Pick the Black RV Slide Out Seal when you already know that 018-312-EKD and 018-341 EK are the right references and you want the lower-cost replacement. Pick the 2 In 1 RV Slide Out Seal when having '2 In 1' right in the name makes the kit easier to identify and the higher price is acceptable. For most RV camper systems accessories repairs, the lower-cost option is the one to choose.
