Cummins engine parts V-shaped clamp C5547632 for dongfeng trucks

Built to address the high-vibration environment of Cummins engines, this V-shaped clamp features a structural design that maximizes clamping force and stability. The clamp body is crafted from 304 stainless steel, offering a tensile strength of ≥515MPa and yield strength of ≥205MPa—resisting deformation even under continuous vibration (5-2000Hz, ISO 16750-3). The V-shaped contact surface (80mm opening) distributes clamping force evenly across the pipe’s outer circumference, increasing contact area by 40% compared to U-shaped clamps. This design prevents pipe slippage during engine operation, especially for high-pressure fuel lines (up to 1600 bar) in Cummins common rail systems. Finite element analysis confirms the clamp maintains a stable clamping force of 80-100N, avoiding pipe displacement that leads to leaks or performance loss

Beyond fixation, the clamp is optimized to protect hoses and pipes from abrasion and leakage. The inner V-surface is lined with a 2mm-thick EPDM (Ethylene Propylene Diene Monomer) rubber pad, which creates a tight seal between the metal clamp and rubber/plastic pipes. The EPDM material resists high temperatures (up to 130℃) from the engine, chemical corrosion from fuel and coolant, and UV aging—maintaining elasticity for ≥150,000km. The rubber pad also eliminates metal-to-rubber friction, a common cause of hose cracking, extending pipe lifespan by 30% compared to unlined clamps. The clamp’s smooth, deburred edges prevent cutting into pipe surfaces, ensuring the integrity of the engine’s fluid and air transfer systems

Designed for Dongfeng trucks operating in diverse and harsh environments—from coastal high-salt areas to dusty construction sites—the clamp exhibits exceptional anti-corrosion performance. The 304 stainless steel body undergoes passivation treatment, forming a protective oxide layer that resists rust and pitting. The M10 fastener is made of 316 stainless steel, passing 2000-hour neutral salt spray testing (ASTM B117) with no red rust. The EPDM rubber pad is inert to road salt, diesel, engine oil, and industrial contaminants, avoiding swelling or degradation. Even in extreme conditions like Xinjiang’s sandy deserts or southern China’s humid climates, the clamp remains free from corrosion-related damage, ensuring consistent performance and avoiding premature replacement

Optimized for fleet maintenance efficiency, the V-shaped clamp features a user-friendly design that simplifies installation and adjustment. It uses a worm-drive locking mechanism that allows precise tightening with a standard screwdriver, enabling technicians to adjust clamping force based on pipe diameter (compatible with 50-70mm outer diameter pipes). The clamp’s compact size (120mm×40mm×20mm) fits in tight spaces within the engine compartment, and the pre-assembled rubber pad eliminates the need for additional gaskets. 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 worm drive indicate the maximum tightening range, preventing over-tightening and pipe damage. This streamlined design reduces fleet downtime and maintenance costs, ensuring quick return of vehicles to service
