Access Tonneau Tailgate Seal

Access Tonneau TRAILSEAL® Tailgate Gaskets: Closing the Gaps That Matter

Even the most rugged pickup truck leaves gaps around the tailgate — and those gaps are an open invitation for dust, rain, and snow to settle onto your cargo. Access Tonneau, the brand behind the industry's first roll-up tonneau cover, engineered a direct solution: the patented TRAILSEAL® Tailgate Gasket, a purpose-built tailgate seal designed to close those perimeter gaps once and for all.

What Makes the TRAILSEAL® Stand Out?

Access Tonneau developed the TRAILSEAL® with the real-world demands of truck owners in mind — from daily drivers on dusty back roads to work trucks in wet, wintry climates. The key features that set it apart include:

• Patented full-perimeter seal: The TRAILSEAL® gasket runs the entire perimeter of your tailgate, eliminating the gaps that standard factory weatherstripping leaves behind.
• Adhesive-backed molded rubber construction: The rubber gasket uses a 3M adhesive backing for a secure, lasting bond to your tailgate frame — no drilling, no hardware required.
• Universal sizing with custom trimming: The seal is thick enough to bridge large gaps yet compresses down to accommodate smaller ones, making it compatible with virtually any pickup truck on the market.
• 3-step installation: Install is as simple as measure and cut, peel the red backing tape, and stick — a process most truck owners complete in minutes.
• Broad compatibility: The TRAILSEAL® works seamlessly with any tonneau cover, soft or hard topper, canopy, or lid, making it the natural complement to any Access roll-up cover or third-party bed cover.

Why a Tailgate Seal Matters — Especially with a Tonneau Cover

Tonneau covers do an excellent job protecting the top of your truck bed, but low pressure created inside the bed while driving can actually draw dust and moisture in through tailgate gaps. This is the exact problem the TRAILSEAL® was built to solve. By sealing the tailgate perimeter, it completes the protective envelope that a tonneau cover starts — keeping cargo, tools, groceries, and gear genuinely clean and dry.

It's no coincidence that Access Tonneau bundles the TRAILSEAL® Tailgate Gasket as a standard included accessory with their premium ACCESS® Limited Edition Roll-Up Cover, recognizing that a cover without a sealed tailgate is only doing half the job.
