Your RV slide-out seal takes a beating every time you extend or retract the room. When it starts letting in wind, dust, or road noise, you need a replacement that fits the 018-312-EKD and 018-341 EK profiles. In rv camper systems accessories, those two profiles show up together in these kits. The challenge: two similar kits are vying for the same slot, one at $53.99 and one at $65.99. Both cover the same two part numbers, so which one is the right call for your camper?
Quick verdict
The $53.99 New For RV Camper Slideout System seal is the straightforward pick. It gives you the 018-312-EKD and 018-341 EK profiles together in black, in new condition, with money-back-or-replacement after-sales. The $65.99 2 in 1 RV Slide Out Seal is the same pair of profiles but with a higher price and a title that leads with '2 in 1.' Unless you specifically want the version that calls out the 2-in-1 format and the tape-removal prep step, the lower-priced kit is the better buy.

Where each kit wins
- The $53.99 New For kit wins if you want the same two profiles at a lower price. It uses tough rubber that handles extreme weather and corrosion, making it a solid all-purpose replacement.
- The $65.99 2 in 1 kit wins if you prefer the product name that explicitly says 2 in 1 and if you value the pre-installation reminder to verify your part numbers and remove tape from the EK seal before assembly.
Product notes
New For RV Camper Slideout System RV Slide Out Seal 018-312-EKD 018-341 EK US
This kit gives you both the 018-312-EKD D seal and the 018-341 EK base in one $53.99 order. The 018-312-EKD profile measures 1" x 15/16" x 35', and the 018-341 EK profile is 1/2" x 2.75" x 35'. It arrives black and new, and the after-sales policy lets you choose a money back or a replacement. The rubber is tough enough to stand up to extreme weather and resist corrosion, which matters when your slide-out faces rain, snow, and road grit. To install, you slide the D seal onto the EK base track and screw it into place. If you're comfortable with that process and want the same profiles without the higher price tag, this is the kit to get.
018-312-EKD 018-341-EK 2 in 1 RV Slide Out Seal For RV Camper Slideout System US
This $65.99 version carries the '2 in 1' name, which tells you up front that the 018-312-EKD and 018-341 EK profiles are bundled together. The dimensions match the cheaper kit exactly: 1" x 15/16" x 35' for the D seal and 1/2" x 2.75" x 35' for the EK seal. It's also black and new, with the same money-back-or-replacement after-sales promise. What sets it apart is the extra prep guidance: make sure your model number and photo match before ordering, and when you install, remove the tape from the 018-341 EK seal first. That's a helpful nudge for someone doing this replacement for the first time. The trade-off is the $12.00 difference for the same two profiles.
Final choice by use case
- First-time replacement: the $53.99 New For kit.
- Buyer who wants the explicitly labeled 2-in-1 bundle and the tape-removal reminder: the $65.99 kit.
- If both kits fit and you just need a working seal, choose the lower-priced one.
