ESI Tailgate Seal for Toyota Tundra — Ultimate EPDM Taper Seal, Weather-Resistant with 3M Adhesive

ESI's Ultimate Tailgate Seal with integrated taper seal is a patented EPDM rubber gasket that blocks dust, fumes and water from entering the bed through the Toyota Tundra tailgate gaps.

If you use a truck cap or a tonneau cover on a Toyota Tundra, the factory tailgate clearance can allow dirt, exhaust odors and moisture to sneak into the bed. The ESI Ultimate Tailgate Seal is engineered to close that gap with automotive-grade EPDM rubber and high-bond 3M ST1200 adhesive. It installs along the tailgate sidewalls and bottom edge to create a continuous seal, and it adheres to painted metal, textured spray-on liners and other common bed finishes.

How does this seal keep water and dust out of my truck bed?

The seal forms a snug barrier around the tailgate perimeter, covering the sidewall and lower gap where contaminants typically enter. EPDM rubber resists compression set and repels moisture so the seal maintains contact even after repeated tailgate use. The high-tack 3M ST1200 tape ensures the gasket stays attached to varied surfaces for a consistent barrier.

• Continuous perimeter gasket for sidewall and bottom gaps
• Weather-resistant EPDM that resists cracking and shrinking
• 3M ST1200 adhesive bonds to painted and spray-on bed liners

Will I be able to install it myself, and what conditions are required?

Yes — the product is designed for consumer installation following the supplied directions. For best adhesion, install only when the air and surface temperatures are between 55° and 104°F (13°–40°C). Prep the mounting surface by cleaning and drying thoroughly and follow the included or online instructions for correct placement.

• Follow packaged or online step-by-step installation guide
• Recommended installation temperature range: 55°–104°F (13°–40°C)
• Surface must be clean, dry and free of contaminants

What materials and durability features does the ESI tailgate seal offer?

The seal is molded from automotive-grade EPDM rubber chosen for long-lasting flexibility and resistance to UV, ozone and temperature variation. A factory-applied 3M ST1200 adhesive strip provides immediate tack and durable bonding to most truck bed finishes. The patented taper profile helps maintain a tight fit without excessive force on the tailgate latch.

• Automotive-grade EPDM for weather and UV resistance
• High-bond 3M ST1200 adhesive for reliable attachment
• Patented taper design to balance seal and tailgate operation
