The Decision: Which RV Slide Out Seal Combo Should You Order?
When your RV camper needs fresh slide out seals, the 018-312-EKD D-seal and 018-341 EK base seal are often sold together as a combo. Two listings in rv camper systems accessories are offering this kit, and they look nearly identical. One is priced at USD 63.99 and the other at USD 85.99. Both are new, black rubber seals with the same dimensions for the D-seal and the base seal. So the real question is whether the higher-priced listing gives you anything extra.
Quick Verdict
For most buyers, the Combo RV Slide Out Seal 018-312-EKD & 018-341 EK at $63.99 is the better pick. It has the same listed dimensions and the same money-back-or-replacement after-sales policy as the costlier 2-in-1 listing. The only meaningful difference is the $22 price gap. Unless the "2 In 1" wording in the other listing makes you significantly more confident about the kit contents, go with the $63.99 combo.

Where the $63.99 Combo Wins
The Combo RV Slide Out Seal listing wins on price. At USD 63.99, it costs $22 less than the 2-in-1 listing while sharing the same 018-312-EKD and 018-341 EK dimensions, the same black new condition, and the same after-sales promise. If you're replacing both seals and don't need any extra wording in the title, this listing makes the most financial sense.
Where the $85.99 2-in-1 Wins
The 2-in-1 listing's only concrete edge is the title phrase "2 In 1," which makes the bundled nature of the kit explicit. Some shoppers may prefer that clarity when they're matching part numbers. Otherwise, every listed spec matches the cheaper combo: the D-seal is still 1' x 15/16' x 35' and the base seal is still 1/2" x 2.75" x 35'. You're paying $22 more for the same listed kit.
Product Notes
Combo RV Slide Out Seal 018-312-EKD & 018-341 EK
The Combo RV Slide Out Seal bundles the 018-312-EKD D-seal with the 018-341 EK base seal in black. At USD 63.99, it's the lower-priced way to get both seals. The dimensions are exactly what you'd expect for this style: the D-seal measures 1' x 15/16' x 35' and the base seal measures 1/2" x 2.75" x 35'. The listing includes a note to confirm that the model numbers and photos match your existing setup before ordering, which is standard for this type of replacement part. The after-sales option is money back or replacement, so you have a clear remedy if something's off. The main limitation is that the title doesn't say "2 In 1," even though the combo includes both pieces. If you're comfortable matching part numbers yourself, this is the listing to choose.
For Rv Camper Slideout System 2 In 1 Rv Slide Out Seal 018-312-Ekd & 018-341 Ek
The 2-in-1 listing spells out "2 In 1" in the title, which can be reassuring if you want to see that both seals are included before you click. The listed price is USD 85.99, and you get the same black, new seals with the same dimensions: 1' x 15/16' x 35' for the 018-312-EKD and 1/2" x 2.75" x 35' for the 018-341 EK. It also offers the same after-sales policy of money back or replacement. The limitation is the price: you're paying $22 more for a kit that is listed with identical dimensions and the same installation approach. If the "2 In 1" wording matters to you, it's a valid choice, but there's no extra seal material or different sizing in the listing.
Final Choice by Use Case
If you want the lower listed price and you're confident the 018-312-EKD and 018-341 EK part numbers match your existing seals, the Combo RV Slide Out Seal at $63.99 is the pick. If you'd rather have a listing that explicitly says "2 In 1" in the title and you're willing to spend $85.99 for that clarity, the 2-in-1 listing will also work. For most RV owners, the $63.99 combo gives you the same listed kit for $22 less.
