-Product Model: 803080628
-Product Name: Filler Cap
– Material specifications: High-quality oil-resistant polymer material, strong toughness and anti-aging, excellent sealing performance, original standard size, tight fit without gaps during installation.
– Processing technology: One-piece injection molding, fine treatment of sealing surface, multiple sealing and pressure resistance quality inspections, dimensional compliance, easy disassembly and assembly for easy maintenance.
The 803080628 filler cap solves common problems associated with ordinary fuel filler caps, such as poor sealing, insufficient toughness, vibration-induced loosening, aging and cracking, pressure relief failure, and fuel evaporation loss. It is a core original equipment manufacturer (OEM) part for sealing and protecting fuel tanks in construction machinery, balancing air pressure, and facilitating routine maintenance and replacement. Made of high-quality polymer material in a single molding process, it undergoes anti-aging, oil-resistant, and corrosion-resistant treatments, and is structurally reinforced. It boasts strong sealing performance, pressure resistance, and durability, making it suitable for harsh working conditions such as high-frequency vibration, dusty and oily environments, and large outdoor temperature differences. It is widely used for sealing and protecting the fuel filler port of construction machinery equipment and for air pressure stabilization.
