Replacing a slide out seal on an RV camper can be confusing when two products show the same part numbers and the same listed kit. The 018-312-EKD D seal and 018-341 EK base seal are sold as a combo, and both entries here appear to offer the same kit. Your real job is deciding which title you trust enough to choose, then double-checking compatibility before you order.
Quick verdict
Both products are functionally identical. The first one leads with 'For RV Camper Slideout System' in the title, while the second says 'Fits RV Camper Slideout System.' Because the combo, price, and dimensions shown are the same, your choice comes down to which wording makes you more confident about compatibility. Either way, verify the model number and photo before ordering.
Both combos are new, black seals that you mount by sliding the D seal onto the EK seal base and screwing the rubber into place. Before ordering, confirm that the model number, part number, and photo match your existing seal. That shared step is the most important part of the purchase, because a slide out seal needs to match the track profile on your RV.

Product notes
Combo RV Slide Out Seal 018-312-EKD & 018-341 EK For RV Camper Slideout System
Choose this combo when you want the title to state exactly what the kit is for: an RV camper slideout system. The part numbers 018-312-EKD and 018-341 EK are front and center, which makes it easier to match against the sticker on your slideout. The seals are new and black, and the set includes both the D seal and the base seal. You should still confirm that the part number and photo match your existing seal before ordering. If you skip verifying the profile, the D seal and base seal may not fit your slideout's track. If the title wording 'For RV Camper Slideout System' gives you confidence, this is a straightforward pick.
Combo RV Slide Out Seal 018-341 EK 018-312-EKD Fits RV Camper Slideout System
This combo uses 'Fits' instead of 'For' and puts 018-341 EK before 018-312-EKD in the title. It's the same kit, so the practical difference is wording. The reverse part-number order can actually be helpful if your slideout documentation lists the EK base first. The seals are new and black, and the set covers the same two parts. Pick it if 'Fits RV Camper Slideout System' reads as a clearer compatibility statement to you. The limitation is the same compatibility check: confirm the model number, part number, and photo before ordering, and remember that no title can guarantee that your slideout uses this seal profile. Use the photo as your final guide.
Final choice by use case
If you want a title that explicitly says 'For RV Camper Slideout System,' choose the first combo. If you prefer a title that says 'Fits RV Camper Slideout System,' choose the second. Since both include the same parts, your final pick should be based on which title you're more likely to match against your own slideout parts.
