Sealing components designed for cargo areas of pickup trucks prevent the ingress of water, dust, and debris. These components, typically made of rubber, foam, or plastic, are affixed to the tailgate, bed rails, and other junctions to create a tight barrier against the elements. A common example is the rubber seal around a tailgate, preventing water from entering the truck bed.
Protecting cargo from damage due to moisture, dirt, and dust is essential for maintaining its value and usability. A properly sealed cargo area can also prevent rust and corrosion within the truck bed itself, extending its lifespan. Historically, simpler materials like felt or basic rubber strips were used. Advancements in materials science have led to more durable and weather-resistant solutions that offer superior protection and longevity.
