Your RV slide-out seal has seen better days. The rubber is worn, the slide-out doesn't close as snugly, and you're already thinking about rain, snow, and the noise coming through the gap. You need a kit that covers both the 018-312-EKD D-seal and the 018-341 EK base, in the right dimensions, and you'd rather not overpay. Two kits are on the table: one with a higher list price, one with a lower list price. Both are new, black, and designed for the same seal model numbers. So what's the real difference? Let's compare.
Quick verdict
Both kits match the same 018-312-EKD and 018-341 EK dimensions, come in black, and are listed as new. The main differentiators are the listed price and the specific points each description calls out. See the table below for the price spread.

Where each kit stands out
- The lower-priced kit stands out for weather-protection messaging: its description highlights keeping away rain, snow, dust, dirt, and noise, plus tough rubber and extreme-weather resistance.
- The higher-priced kit stands out for installation guidance: it's the one whose description explicitly says "EASY INSTALLATION" and points to a concrete first step-remove the tape from the 018-341 EK seal before sliding the D-seal onto the base.
- Both list the same 018-312-EKD and 018-341 EK dimensions, so sizing doesn't separate them.
Product notes
For Rv Camper Slideout System 2 In 1 Rv Slide Out Seal 018-312-Ekd & 018-341 Ek (USD 85.99)
This is the pricier kit of the two. If you want the product description to spell out the installation flow, this one is explicit: it says "EASY INSTALLATION" and tells you to remove the tape from the 018-341 EK seal before sliding the D-seal onto the base track. That can be reassuring if you are doing the job yourself. However, at $85.99, it is the higher-priced option by $32.00, and it does not mention weather protection or tough rubber the way the other description does. If your main goal is simply to get the right model numbers at the lowest listed cost, this kit isn't the one.
New For RV Camper Slideout System RV Slide Out Seal 018-312-EKD 018-341 EK US (USD 53.99)
At $53.99, this kit is the lower-priced choice and it leans into weather-readiness. The description says it "keeps away rain, snow, dust, dirt and noises," is "made from tough rubber," and can "withstand extreme weather." That is a big deal if your camper sits outside. The trade-off is that it does not call out an "easy installation" step like the more expensive option does, so you may need to work through the tape removal and base alignment without that explicit prompt. If you are shopping on price and want the weather-protection messaging, this kit is the stronger pick.
Final choice by use case
Choose the higher-priced kit if you want a product description that explicitly highlights easy installation and a step-by-step start. Choose the lower-priced kit if your priority is a lower list price and weather-resistance messaging for rain, snow, dirt, and noise. For most shoppers looking to cover both seal models at the lowest listed cost, the $53.99 kit is the natural pick.
