Oil Drain Valve ESOC
Detroit Diesel

This ESOC oil drain valve is a high-performance control valve designed to manage oil drainage in the engine’s oil circuit. Featuring a threaded connection sized M27X2, the valve provides a secure, leak-tight interface that stands up to the rigors of routine oil changes and maintenance workflows. The valve is engineered to tolerate hot oil and frequent cycling, preserving system integrity while enabling efficient drainage during servicing. In practice, it supports controlled evacuation of oil from the ESOC subsystem, aiding in maintenance efficiency and minimizing potential spills or contamination. The VMRS 045-013-018 categorization places it within the oil drain valve family, guiding technicians through proper replacement and compatibility checks within Detroit Diesel platforms. The part is primarily used where an accurate, reliable drain point is required for service procedures, offering predictable performance and long service life in demanding operational environments.
