Compatible With All Capser Tonneau Covers
Capser Tonneau Cover Seal Kit
Replacement rail and tailgate seals to restore a weathertight fit as your cover ages. A worn seal is the most common reason water starts getting into a covered bed — this kit fixes that without replacing the whole cover.
Shop This KitOverview
Every Capser tonneau cover relies on a weather seal strip around the frame to keep rain and road spray out of the bed. Like any rubber seal, it gradually stiffens and loses compression over years of sun and temperature exposure. This kit gives you a fresh seal strip sized to match the frame used across the Capser hard and soft cover lineup.
Replacing a worn seal is the most effective fix for a cover that used to seal tight but has started letting water through, and it’s a fraction of the cost and effort of replacing the entire cover.
What’s Included
Frame Seal Strip
Full-length seal strip sized to run the perimeter of the frame on Capser hard and soft covers.
Tailgate Seal
A separate tailgate seal strip that seats against the tailgate edge to block water from the rear of the bed.
Adhesive Backing
Both seals use a weatherproof adhesive backing for a clean, no-tools installation.
Install Guide
A printed installation guide walks through removing the old seal and seating the new one evenly.
Checking Compatibility
This seal kit is sized to fit the frame and tailgate seal channels used across the Capser hard tri-fold, soft tri-fold, soft roll-up, and soft quad-fold cover lineup. If you’re not sure which seal profile your cover uses, check the model name on your original packaging or email us your truck and cover style and we’ll confirm before you order.
How Installation Works
- Remove the old seal. Peel the worn seal off the frame, cleaning off any old adhesive residue.
- Clean the surface. Wipe the frame dry so the new adhesive backing bonds properly.
- Seat the new frame seal. Press the new seal onto the frame starting from one end, working it in evenly.
- Install the tailgate seal. Apply the tailgate seal strip along the tailgate edge per the included guide.
- Test the fit. Close the cover and check that it compresses the new seals evenly along the full length.

Frequently Asked Questions
How do I know if my seals need replacing?
If the rubber feels stiff, is visibly cracked, or you’ve noticed water getting into the bed after rain, it’s time to replace the seals.
Will this fit my specific cover style?
This kit is sized for the standard frame and tailgate seal channel used across the Capser hard and soft cover lineup. Email us your cover model if you want to confirm before ordering.
Do I need any tools to install it?
No. Both seals use an adhesive backing that presses directly onto the frame — no drilling, cutting, or special tools required.
How long does the new seal last?
The rubber compound typically holds up for several years of regular outdoor exposure before it needs replacing again.
