Dongfeng KR truck spare parts clamp 1109034-KS111 in stocked

Crafted for the rigorous operating conditions of commercial trucks, this clamp features a dual-material construction that balances strength and durability. The band and bracket are made of 304 stainless steel, offering tensile strength ≥515MPa and excellent resistance to fatigue caused by road vibrations (5-2000Hz, ISO 16750-3). The 1.5mm-thick stainless steel band resists deformation even under constant pressure from pressurized hoses (up to 1.2MPa for fuel lines), preventing hose slippage or displacement. The mounting bolt uses grade 8.8 high-strength steel with a zinc-plated finish, ensuring secure attachment to the chassis without thread stripping—even after repeated maintenance. This robust material selection ensures the clamp maintains structural integrity for ≥150,000km of service

Beyond fixation, the clamp is optimized to protect hoses and pipelines from abrasion and leakage. The inner surface of the stainless steel band is lined with a 2mm-thick EPDM (Ethylene Propylene Diene Monomer) rubber pad, which creates a tight seal between the clamp and hose while preventing metal-to-rubber friction. The EPDM pad resists high temperatures (up to 130℃) from engine heat and chemical corrosion from fuel, coolant, and brake fluid, maintaining elasticity for years. The band’s smooth, deburred edges eliminate the risk of cutting into hose surfaces, a common issue with low-quality clamps that leads to leaks. This design not only extends hose lifespan by 30% but also ensures reliable fluid and air transfer, reducing the risk of system failures

Designed to endure Dongfeng KR’s diverse operating regions—from coastal high-salt areas to dusty construction sites—the clamp exhibits exceptional anti-corrosion performance. The 304 stainless steel components undergo a passivation treatment, forming a protective oxide layer that resists rust and pitting. The zinc-plated bolt and nut pass 1000-hour neutral salt spray testing (ASTM B117) with no red rust, while the EPDM rubber pad is inert to road salt, diesel, and industrial contaminants. Even in harsh conditions like Xinjiang’s dusty deserts or southern China’s humid climates, the clamp remains free from corrosion-related degradation, ensuring consistent performance and avoiding premature replacement

Optimized for fleet maintenance efficiency, the clamp features a user-friendly design that streamlines installation and adjustment. It uses a worm-drive locking mechanism that allows tool-free tightening with a standard screwdriver, enabling precise adjustment of clamping force (50-100N) to match different hose diameters. The U-shaped bracket’s pre-drilled hole aligns perfectly with the chassis’s original mounting points, requiring only a torque wrench (25-30N·m) to secure the M8 bolt. A single technician can install or replace the clamp in 5 minutes, a 60% reduction in time compared to traditional bolted clamps. Clear laser markings on the band indicate the maximum tightening range, preventing over-tightening and hose damage, while the compact size (65mm×35mm) fits in tight spaces within the engine compartment
