When your RV slideout seal wears out, you'll be looking for a combo that includes the 018-312-EKD and 018-341 EK profiles. Two nearly identical kits cover these part numbers: the Combo RV Slide Out Seal and the RV Slide Out Seal Combo. Both come in black, both are new, and both share the same money-back-or-replacement promise. The real difference is price, and that's what we'll unpack.
Quick Verdict
For most RV owners, the RV Slide Out Seal Combo is the better buy. It matches the pricier kit on the seal profiles, color, and condition, but comes in at the lower end of the price range. Its description also emphasizes weather and corrosion resistance, which the other kit doesn't call out. The Combo RV Slide Out Seal is the only one that mentions a high-quality finish, so if that detail matters, it may be worth the extra cost.
Price and Specs at a Glance
| Kit | Price | Price Bar | After-sales | Special Note |
|---|---|---|---|---|
| Combo RV Slide Out Seal | USD 63.99 | Money back or replacement (buyer's choice) | Notes a high-quality finish | |
| RV Slide Out Seal Combo | USD 53.00 | Money back or replacement (buyer's choice) | Emphasizes weather and corrosion resistance |
Both kits list the same dimensions for the 018-312-EKD and 018-341 EK seals, so the fit matches between the two.
Where Each Product Wins
Combo RV Slide Out Seal wins if you want a finish detail. The higher-priced kit is the only one that mentions a high-quality finish. If that finish detail is important to you, this is the direction to go. The rest of the specs line up with the cheaper kit, so you're mainly deciding whether the finish is worth the extra cost.
RV Slide Out Seal Combo wins on price and weather protection. The lower-priced kit is the cheaper option. Its description calls out resistance to rain, snow, dust, dirt, and noise, plus corrosion and extreme weather. That makes it a compelling choice if your camper sits outside in harsh conditions.
Product Notes
Combo RV Slide Out Seal 018-312-EKD & 018-341 EK For RV Camper Slideout System
At USD 63.99, this is the higher-priced kit. The concrete reason to choose it is the high-quality finish mentioned in the specs, which is something the cheaper kit doesn't call out. The installation method is straightforward: slide the 018-312-EKD D seal onto the 018-341 EK seal base and screw the rubber into place, and both kits share that easy-install design. The limitation is the extra cost: you're paying more for the finish note, while the description leaves out the weather and corrosion resistance that the lower-priced kit emphasizes. If you don't care about the finish detail, you may be better off saving the money.
RV Slide Out Seal Combo 018-312-EKD + 018-341 EK for RV Camper Slideout System
For USD 53.00, this kit is the lower-priced choice. The reason to choose it is the price and the weather-ready emphasis in its description: it specifically says the seals keep out rain, snow, dust, dirt, and noise, and resist corrosion and extreme weather. The installation is the same easy slide-and-screw approach as the pricier kit, so you're not sacrificing ease of fit. The limitation is that it doesn't mention a high-quality finish, so if that visual detail matters to you, you'll find it only on the more expensive kit. Overall, the cheaper combo offers the same core seal profiles for USD 10.99 less.
Final Choice by Use Case
If your main priority is saving money and getting a replacement that handles weather and corrosion, choose the RV Slide Out Seal Combo. If you're willing to spend a little more for a high-quality finish note, pick the Combo RV Slide Out Seal. For the majority of RV owners, the lower-priced kit delivers the same core seal profiles for less.
