ESI Tailgate Seal for Ford F150/F250/F350/F450/Raptor/Lightning — Large Tapered EPDM with 3M Adhesive, Made in USA

This upgraded kit from ESI replaces the original configuration with fewer cut pieces while keeping backward compatibility across all Ford model years for F150, F250, F350, F450, Raptor and Lightning trucks. Engineered from automotive-grade EPDM and pre-lined with 3M ST1200 adhesive tape, the seal adheres to painted metal and spray-on bed liners. The kit is made in the USA and includes clear installation instructions; proper bonding requires surface and air temperatures between 55°F and 104°F (13°C–40°C) and 25 pounds of applied pressure.

How does this tailgate seal reduce dust and water intrusion?

The ESI Ultimate Tailgate Seal creates a tight barrier along the tailgate’s bottom edge and sidewalls so airborne dust and driving spray have fewer entry points into the truck bed when a cap or cover is installed. Its tapered design compresses against uneven gaps without deforming, preserving seal integrity over time.

• Automotive-grade EPDM rubber resists weathering and retains flexibility.
• Tapered profile conforms to tailgate edges and sidewall contours.
• 3M ST1200 adhesive secures the seal to painted and textured surfaces.

Which Ford trucks and tailgate types are compatible with this kit?

This kit is intended for use on all Ford model years of F150, F250, F350, F450, Raptor and Lightning pickups. It uses the Large Tailgate Seal for the sidewalls to eliminate two smaller cut pieces used in the original design, simplifying installation for these specific trucks.

• Compatible: All Ford model years — F150, F250, F350, F450, Raptor, Lightning.
• Not compatible: Ford Ranger, Ford Maverick, or trucks with Pro Access Tailgate configurations.
• If you need the Standard Tailgate Seal for other pickups, search the alternate part (ASIN B00IPQWXZQ).

What materials and installation conditions should I know about?

The seal is manufactured from automotive-grade EPDM rubber for long-lasting elasticity and weather resistance. Adhesion comes from factory-applied 3M ST1200 double-sided tape, but correct surface prep and application conditions are essential for a durable bond.

• Material: EPDM rubber — resists UV, ozone and temperature cycling.
• Adhesive: 3M ST1200 tape — bonds to painted and spray-on bed liners.
• Installation: Surface temperature 55°F–104°F (13°C–40°C); 25 lbs of applied pressure needed for full bond.

Will installation change the look or clearance of my tailgate?

The taper profile is low-profile and meant to fit discreetly along the tailgate bottom and sidewalls without interfering with normal operation of the tailgate or tailgate accessories. When applied correctly, it maintains a clean factory-like appearance while improving protection from the elements.

• Low-profile design preserves tailgate operation and clearance.
• Adheres flush to painted surfaces and textured bed liners.
• Packaged or online instructions show exact fitment and trimming points.

Who is this for: The ESI Ultimate Tailgate Seal with Taper Seal is aimed at Ford pickup owners who use a truck bed cap or tonneau cover and want a reliable, long-lasting solution to reduce dust and water entry. It’s especially suitable for F150, F250, F350, F450, Raptor and Lightning drivers who prefer an easier-install kit built in the USA with robust materials. If your truck is a Ford Ranger, Maverick, or has a Pro Access Tailgate, select the model-specific kit designed for those configurations.
