Dongfeng kinland Single tube clamp CQ68622-E in stocked

Crafted from high-grade galvanized carbon steel, the CQ68622-E single tube clamp offers exceptional resistance to corrosion, rust, and mechanical impact—essential for withstanding the harsh operating conditions of commercial trucks (e.g., road salt, moisture, dust, and constant vibration). The clamp’s surface undergoes a multi-layer galvanization process, providing a protective barrier that extends its service life to over 50,000 miles under standard use. Additionally, the clamping bolt is made of heat-treated alloy steel, delivering high tensile strength (up to 800 MPa) to prevent loosening under heavy loads or extreme temperature fluctuations (-40°C to 120°C)

Unlike multi-tube clamps that risk tube-to-tube friction and abrasion, the CQ68622-E features a dedicated single-tube configuration. This design ensures each tube is independently secured, minimizing contact between adjacent tubes and reducing the risk of leaks or damage caused by rubbing. The clamp’s closed-loop structure provides 360° contact with the tube, distributing pressure evenly to avoid deformation while maintaining a tight, secure hold. It is ideal for use with rigid or semi-rigid tubes in Dongfeng Kinland’s engine bay, chassis, or undercarriage, where space constraints or tube sensitivity demand isolated fastening

Designed for ease of maintenance, the CQ68622-E single tube clamp features a thumb-screw locking mechanism that enables tool-free installation and removal. This saves time during routine inspections or tube replacements, eliminating the need for wrenches or pliers. The clamp also offers adjustable tension: the thumb screw can be tightened to the desired firmness, ensuring a custom fit for different tube diameters (within the 8-12mm range) while preventing over-tightening that could crack or damage the tube. The mounting base includes pre-drilled holes for quick alignment with Dongfeng Kinland’s existing chassis mounting points, further simplifying the installation process

The Dongfeng Kinland Single Tube Clamp CQ68622-E meets rigorous international quality and safety standards, including ISO 9001 (quality management) and SAE J1455 (automotive tube fastening requirements). It undergoes comprehensive testing, including salt-spray corrosion tests (480 hours), vibration endurance tests (100,000 cycles at 5-200 Hz), and temperature shock tests (-40°C to 120°C, 50 cycles), ensuring reliable performance in extreme environments. By adhering to these standards, the clamp minimizes the risk of tube failure— a critical safety concern for heavy-duty trucks, as tube leaks can lead to brake system malfunctions, hydraulic power loss, or fuel system hazards
