JCB HIGH-QUALITY EXCAVATOR PARTS MADE IN CHINA NEW ME074442 OIL COOLER SPARKLING MACHINERY
SPARKLING MACHINERY NEW ME074442 Oil Cooler is a core thermal management component for JCB excavators (heavy-duty construction/mining use). It cools high-temperature hydraulic oil or engine oil to maintain optimal oil viscosity and system efficiency.
Meeting JCB OEM standards (ME074442), it resists -30°C to 120°C temps, corrosion, and oil contamination, ensuring seamless compatibility and long-term reliable cooling performance.
VOLVO EXCAVATOR PARTS MADE IN CHINA NEW L90E L70E L60E A30D L150E 22996281 PRESSURE SWITCH SPARKLING MACHINERY
SPARKLING MACHINERY NEW L90E L70E L60E A30D L150E 22996281 Pressure Switch is a critical hydraulic safety monitoring component for Volvo L90E, L70E, L60E, A30D, and L150E excavators (widely used in construction, mining, and material handling projects). As the "hydraulic pressure alert trigger", it real-time monitors pressure fluctuations in hydraulic circuits—automatically sending signals to the excavator’s control unit when pressure exceeds or drops below safe thresholds. This ensures timely protection during tasks like lifting heavy loads or digging, preventing overpressure damage to pumps/valves and underpressure-related operational failures.
