Dongfeng Kinland truck spare parts Bent through quick insertion tube connector RQ83222N6E

Built to eliminate the inefficiencies of traditional pipeline connections, this connector features an advanced push-to-connect mechanism that requires no wrenches, crimpers, or sealants. The integrated assembly includes a 304 stainless steel locking collet, pre-installed seal ring, and ergonomic release sleeve: technicians simply insert the Φ16mm compatible tube into the connector until a distinct “click” confirms secure engagement, completing installation in 10 seconds—80% faster than threaded connectors. The 90° elbow design is optimized for Dongfeng Kinland’s compact chassis layout, allowing pipeline routing around fuel tanks, battery boxes, and brake cylinders without kinking (which causes 15-20% pressure loss). A textured release sleeve enables easy disassembly by pressing and pulling the tube, reducing maintenance time for transmission cooling line repairs by 75%

As a critical component for preventing fluid and gas leakage, the RQ83222N6E integrates a triple-layer sealing structure that meets the rigorous demands of truck systems. The primary seal is a food-grade EPDM rubber ring (Shore A hardness 70) that conforms to the tube’s outer surface, maintaining a leak-tight seal under 2.0MPa working pressure (air brake peak pressure) for 48 consecutive hours. A secondary FKM O-ring seals the threaded interface, resisting swelling and degradation from diesel fuel, transmission oil, and road salt. The third layer is a labyrinth dust shield between the locking collet and tube, blocking debris from entering the sealing area. This system prevents catastrophic failures like air brake auxiliary leaks (compromising braking efficiency) and transmission oil leaks (causing overheating and $2,000+ repair costs)

Engineered to withstand the extreme conditions of truck operation, the connector features a rugged, durable build. The main body is precision-machined from lead-free brass (CuZn39Pb3) with a 2.5mm wall thickness, achieving a tensile strength of 320MPa and resisting deformation from chassis vibration (10-500Hz). The surface undergoes a three-step anti-corrosion treatment: zinc plating (12μm thickness), passivation, and a clear chromate topcoat, passing 2000-hour neutral salt spray testing (ASTM B117) with no rust or pitting—ideal for coastal regions and snowy areas. The locking collet is made of 316 stainless steel (HRC 45) for wear resistance, enduring 150+ insertion/removal cycles without fatigue. All seals operate stably from -40℃ to 125℃, adapting to frigid winters and high-temperature engine bays

This quick-insert connector delivers significant cost savings and system protection for Dongfeng Kinland operators. Its tool-free design cuts labor costs by 60% compared to traditional connectors, while the fast disassembly feature minimizes downtime—critical for logistics fleets where every hour of idleness costs $800+. The leak-proof sealing prevents costly issues: air suspension leaks (repair costs up to $500) and transmission oil leaks (wasting $15-20 per liter of oil). As a genuine OE part, it avoids mismatched aftermarket connectors that cause tube damage (a 5m transmission cooling hose costs $200+ to replace). The connector’s 250,000km service life—three times that of non-OE alternatives—reduces replacement frequency. Backed by a 1-year/150,000km Dongfeng warranty, it ensures reliable pipeline performance and predictable maintenance expenses, safeguarding the truck’s critical systems
