COCK - DRAIN (Komatsu KO3EF-04-41170)

A drain cock that does not seal properly can allow coolant or other fluids to leak, leading to system inefficiency or component damage. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO3EF-04-41170. The drain cock functions as a manual valve to release fluid from a reservoir or system when opened. A common failure consequence is that a stuck or corroded drain cock may prevent complete fluid drainage during service. In a typical usage context, this part is accessed periodically to drain accumulated water or sediment from a system. The part is a simple mechanical valve that relies on a threaded or lever-operated mechanism to open and close. Verify the serial number or application, then call (562) 693-7748.
