Dongfeng xinjiang truck parts Right trailer hook pin cover 8406040-TXGG01T

Built to protect the right trailer hook pin from harsh operating conditions, this cover provides multi-layer defense against corrosion, debris, and physical wear. The cover’s main body is made of weather-resistant TPO (thermoplastic polyolefin) material, which resists water, road salt, and chemical contaminants—preventing rust on the hook pin’s metal surface (a common issue with unprotected pins). Its closed-top design blocks dust, sand, and mud from entering the pin’s locking mechanism, avoiding jamming that could delay trailer coupling. Additionally, the cover acts as a buffer against minor impacts (e.g., from loading equipment or road debris), preventing scratches or dents on the hook pin’s precision-machined surface. In tests, hooks protected by this cover showed 80% less corrosion after 12 months of use in coastal or winter road conditions compared to unprotected hooks

Engineered for long-term durability in trucking applications, the cover uses high-performance materials and reinforced structures to resist wear and tear. The TPO material has a tensile strength of ≥20MPa and elongation at break of ≥300%, ensuring it doesn’t crack or break under temperature fluctuations (-40℃ to 80℃) or repeated handling. The cover’s snap-fit edges are reinforced with 1.5mm-thick ribbing, enhancing resistance to deformation from frequent removal and installation (tested to 500+ cycles without loss of fit). A built-in rubber gasket (EPDM material) around the inner edge creates a tight seal with the hook body, preventing water intrusion while maintaining flexibility. Unlike cheap plastic covers that become brittle in cold weather, this unit retains elasticity and structural integrity even in extreme environments, ensuring a service life of over 5 years

Designed for convenience during trailer coupling operations, the cover features an intuitive, tool-free design that simplifies use for drivers or maintenance staff. It includes a raised, non-slip grip tab (15mm wide) on the top surface, providing a secure hold for easy removal—even when wearing gloves or with greasy hands. The snap-fit mechanism requires only moderate force (30-40N) to attach or detach, eliminating the need for tools like screwdrivers or pliers. The cover’s lightweight design (only 85g) reduces fatigue during repeated handling, and its compact size (outer diameter: 45mm) ensures it doesn’t interfere with the hook’s coupling range. A color-coded red indicator dot on the grip tab helps quickly identify the right-side cover (matching Dongfeng Xinjiang’s left-right color standard), reducing confusion during busy loading operations

Beyond functionality, the cover is designed to align with Dongfeng Xinjiang’s truck aesthetics and safety standards. Its exterior surface features a matte black finish that matches the factory trailer hook assembly’s color, maintaining a cohesive, professional look for the truck’s rear end. The cover’s smooth, rounded edges eliminate sharp protrusions, reducing the risk of injury to personnel during hook maintenance. Additionally, it complies with industry safety standards for trailer components (e.g., ISO 1103) by not obstructing the hook pin’s visibility or the trailer coupling’s safety lock. A small drainage hole at the bottom prevents water accumulation inside the cover, avoiding freeze-thaw damage in cold weather while maintaining protection. This combination of aesthetics and safety ensures the cover meets both practical needs and brand consistency for Dongfeng Xinjiang truck owners
