Dongfeng Kinland truck parts Bent through quick insertion tube connector RQ83216N6E

Built as a critical component for efficient pipeline connection and maintenance, this tube connector adopts an advanced push-to-connect design that eliminates the need for tools like wrenches or crimpers. The connector features a built-in stainless steel locking claw and a pre-assembled EPDM seal ring; technicians only need to insert the matching Φ16mm tube into the connector until a “click” is heard (indicating secure locking), completing installation in 10 seconds—80% faster than traditional threaded connectors. The 90° bending angle is optimized for Dongfeng Kinland’s compact chassis layout, allowing pipeline routing around other components without excessive bending (which causes tube fatigue). A built-in release ring enables easy disassembly by pressing and pulling the tube, facilitating quick pipeline maintenance or replacement

Engineered to prevent fluid or gas leakage in critical truck systems, the RQ83216N6E connector integrates a three-layer sealing structure for reliable performance. The primary seal is a food-grade EPDM rubber ring (Shore A hardness 75) that forms a tight bond with the tube’s outer wall, tested to withstand 1.2MPa pressure (air brake system peak pressure) with no leakage for 24 hours. A secondary O-ring (FKM material) seals the thread interface, resisting corrosion from diesel fuel and coolant. The third layer is a labyrinth structure between the locking claw and tube, blocking dust and moisture from entering the sealing area. This multi-layer design ensures leak-proof operation in air brake systems (preventing brake failure) and fuel systems (avoiding fuel waste and fire risks)

Optimized to endure the harsh operating environment of truck chassis, the connector is crafted from high-performance materials for long-term durability. The main body is made of zinc-plated brass (CuZn39Pb3) with a thickness of 2.5mm, achieving a tensile strength of 320MPa and resisting deformation from chassis vibration (10-500Hz). The zinc plating (8μm thickness) undergoes passivation treatment, passing 1500-hour neutral salt spray testing (ASTM B117) with no rust—ideal for use in coastal or snowy regions with road salt. The locking claw is made of 304 stainless steel (HRC 45), ensuring no fatigue or deformation after 100+ insertion/removal cycles. The EPDM and FKM seals maintain elasticity across a temperature range of -40℃ to 120℃, avoiding hardening or swelling

This quick-insert tube connector delivers significant cost savings and system protection for Dongfeng Kinland operators. Its tool-free installation reduces labor costs by 60% compared to traditional connectors, while the fast disassembly design cuts maintenance time for pipeline repairs by 70% (critical for minimizing downtime in logistics fleets). The leak-proof sealing prevents costly issues: air brake leaks (which cause brake inefficiency and $500+ repair costs) and fuel leaks (costing $0.8-1.2 per liter of wasted fuel). As a genuine OE part, it avoids mismatched aftermarket connectors that cause tube damage (replacing a 5m air brake hose costs $150+). Backed by a 1-year/150,000km Dongfeng warranty, it provides reliable pipeline connection and predictable maintenance expenses, ensuring the safe operation of critical truck systems
