Dongfeng kinland Bent through quick insertion tube connector RQ83222N8E

At the core of the RQ83222N8E connector is its innovative quick-insertion technology, which allows tool-free, one-step tube connection. Users simply align the compatible tube (matching the connector’s inner diameter specification, usually 8mm) with the connector’s inlet, push until a distinct “click” is heard—indicating secure engagement—and the connection is complete. This design drastically reduces installation time compared to traditional threaded or crimped connectors (cutting assembly time by up to 70%), making it ideal for high-volume production lines or emergency on-site repairs. The quick-insertion mechanism also eliminates human error from over-tightening or under-tightening, ensuring consistent connection quality across every use

Exclusively developed for Dongfeng Kinland heavy-duty trucks, the RQ83222N8E connector is engineered to match the OEM’s strict dimensional and performance standards, ensuring flawless integration with the truck’s hydraulic, fuel, or air brake systems. It is compatible with a range of tube materials commonly used in Dongfeng Kinland vehicles, including nylon, polyurethane, and reinforced rubber tubes (with outer diameters corresponding to the connector’s 8mm inner bore). The connector’s inlet and outlet ports are precision-machined to ensure a tight seal with the tube’s outer surface, preventing fluid or air leakage even under high operating pressures (up to 1.6 MPa, suitable for most heavy-duty truck hydraulic/air systems)

The RQ83222N8E connector is constructed from a combination of industrial-grade reinforced nylon (for the housing) and stainless steel (for the internal locking components), delivering exceptional resistance to wear, corrosion, and temperature fluctuations. The nylon housing undergoes a UV-stabilization treatment, protecting it from degradation caused by prolonged exposure to sunlight—critical for undercarriage or engine bay installations. The stainless steel locking clips and O-rings (made of nitrile rubber) resist rust, oil, and chemical erosion (compatible with diesel fuel, hydraulic oil, and brake fluid), ensuring a long service life (up to 80,000 miles under standard operating conditions). Additionally, the connector’s structure is impact-resistant, withstanding minor collisions or vibrations common in heavy-duty truck operations

The Dongfeng Kinland Bent through Quick Insertion Tube Connector RQ83222N8E complies with global automotive safety standards, including ISO 14001 (environmental management) and SAE J2494 (quick-connect fittings for fluid systems). It undergoes rigorous testing to validate its reliability: pressure retention tests (maintaining 1.6 MPa for 24 hours without leakage), pulse pressure tests (100,000 cycles of pressure variation from 0 to 1.6 MPa), and temperature cycle tests (-30°C to 120°C, 100 cycles). The connector’s internal O-ring creates a hermetic seal, eliminating the risk of fluid or air leaks that could lead to system failures (e.g., hydraulic power loss or brake inefficiency). Furthermore, the quick-insertion locking mechanism includes a secondary safety tab, preventing accidental disconnection during vehicle operation—adding an extra layer of protection for critical truck systems
