When you're browsing rv camper systems accessories, replacing the slideout seal is one of those small jobs that keeps the whole rig comfortable. If drafts, water, or dust are sneaking in around a slide, a worn D seal or EK base seal is often the culprit. The 2-in-1 kit is designed to cover both pieces at once. You might find two very similar offers separated by about $20. Both describe the same seal, and the main difference on paper is the price and the wording of the product name. So which should go into your cart?
Quick verdict
For most RV owners, the cheaper option is the better buy because it lists the same part numbers and carries a $20 lower price. The only reason to consider the higher-priced kit is if you prefer its title wording.

Where each product wins
- Price: The lower-priced option clearly wins. The $20 gap is the deciding factor when the other specs match.
- Product-name wording: The higher-priced option starts with "For Rv Camper Slideout System" and uses a different word order. If that phrasing matches how you look up parts, you might find it easier to recognize.
- Shared strengths: Both include a new high-quality finish.
Product notes
018-312-EKD 018-341-EK 2 in 1 RV Slide Out Seal For RV Camper Slideout System US
The lower-priced kit matches the higher-priced kit on the dimensions shown in the table, so you're getting the same 018-312-EKD and 018-341-EK set. Its title leads with the part numbers, which makes it easy to identify before you order. You also get the same after-sales choice of money back or replacement. The limitation is that the title doesn't begin with "For Rv Camper Slideout System," so if that wording matters to you, the other option will be easier to recognize. Paying $20 less for the same seal makes this the stronger choice for most RV owners.
For Rv Camper Slideout System 2 In 1 Rv Slide Out Seal 018-312-Ekd & 018-341 Ek
The higher-priced kit matches the cheaper kit on the listed specifications and installation method. Its product name begins with "For Rv Camper Slideout System," which can help if you identify the seal by the system description rather than the part number. The finish and condition are the same. The drawback is the $20 higher price for what appears to be the same 2-in-1 seal. Unless you prefer the title wording, you're paying extra for the same kit.
Final choice by use case
If you're replacing a worn slideout seal and want the lower price, choose the $65.99 option. If you specifically want the title to begin with "For Rv Camper Slideout System," the $85.99 option is there. For most buyers, the lower-priced kit is the right call.
