Car 7-Way Blade to 4-Way Flat Trailer Adapter, Waterproof & Heat-Resistant Trailer Adapter Plug, RV Connector for Signal Light Display, for Commercial Vehicles, Semi-Cars, Trucks (Black)

1. The 7-pin blade-to-4-pin flat trailer adapter is constructed from engineering plastic and copper contacts. It is robust and durable while ensuring current transmission with minimal loss. The copper contacts do not generate excessive heat2. The housing features a sealed design with excellent waterproofing and superior insulation. It operates reliably in harsh weather conditions like rain, preventing safety hazards such as short circuits or fires

• Thermal & Abrasion Resistance: The housing utilizes high-temperature-resistant engineering plastic, offering durability, abrasion resistance, and excellent insulation. It withstands moderate impacts without damage, resists softening or deformation under intense summer heat, and remains crack-free in winter cold.
• Precision Conversion: The connector enables seamless conversion between 7-pin blade connectors and 4-pin flat connectors, perfectly resolving interface mismatch issues. Whether addressing factory incompatibility or temporary trailer swaps, it ensures rapid connection.
• Superior Conductivity: Contact points are crafted from premium copper metal. Compared to inferior metal terminals in standard adapters, this design minimizes transmission loss and prevents terminal overheating caused by excessive resistance.
• Sealed Waterproof Design: Constructed with a sealed structure and high-temperature resistant materials, this converter effectively blocks rainwater and car wash water from infiltrating internal circuits. This prevents short circuits and safeguards your usage safety.
• Packaging Specifications: You will receive one 7-pin blade-to-4-pin flat trailer adapter. Its dimensions are 3.74 " x 2.75 ", with a base diameter of 1.61 ". Widely compatible with various commercial vehicles, semi-trailers, and trucks. Please verify dimensions before purchase.
