Choosing a replacement seal for your RV camper slideout usually comes down to matching the part. Here, two kits offer the same seals, but at different price points. The RV Slide Out Seal Combo is the more affordable of the two, while the 018-312-EKD 018-341-EK 2 in 1 RV Slide Out Seal US kit carries a higher price. Which one should you order?
Quick verdict
The good news is that both kits carry the same part numbers and are described as new black rubber sets. The real decision is whether the higher-priced 2-in-1 US kit buys you anything beyond the lower-priced combo kit. For most RV owners, the RV Slide Out Seal Combo is the practical pick because it delivers the same part set for less money.

Where each product wins
RV Slide Out Seal Combo wins on price. It asks for less money while sharing the same part set and color as the 2-in-1 US kit.
2 in 1 US Kit wins on title clarity and pre-order confidence. It spells out "2 in 1" and "US," and the description tells you to match the model number, part number, and photo before ordering. That extra step can help you avoid ordering the wrong seal.
Product notes
RV Slide Out Seal Combo 018-312-EKD + 018-341 EK
This kit bundles the D seal with the base seal and walks you through sliding the D seal onto the base and screwing the rubber into place. The description calls out tough rubber that keeps away rain, snow, dust, dirt, and noise. It is the lower-priced of the two options, so if these are the seals your slideout uses, this is the financially sensible pick. The main trade-off is the title: it leads with "Combo" rather than "2 in 1" or "US," so you need to be comfortable that the model numbers in the title match your rig.
018-312-EKD 018-341-EK 2 in 1 RV Slide Out Seal For RV Camper Slideout System US
This kit uses "2 in 1" and "US" in the title, which makes it easy to spot if you are looking for a set described that way. The description goes a step further by telling you to confirm the model number, part number, and photo before you order, and it includes an easy-install reminder to remove the tape from the base seal before sliding the D seal into place. It is the higher-priced of the two options, so the extra cost is the trade-off. If you do not need that pre-order confirmation, the combo kit would probably be enough.
Final choice by use case
- If you want the lower-priced kit: Go with the RV Slide Out Seal Combo. It has the same dimensions and fit as the 2-in-1 US kit, and the after-sales policy is the same money-back-or-replacement option.
- If you want the "US" label and the extra part-match reminder: Go with the 018-312-EKD 018-341-EK 2 in 1 RV Slide Out Seal US kit. You pay more, but the title and the order-check note give you an extra layer of confirmation.
