COCK DRAIN (Komatsu KO34B04111140)

A worn cock drain can allow coolant or oil to seep past the valve seat, leading to gradual fluid loss. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO34B04111140. The cock drain functions as a manually operated valve that opens to drain fluids from a reservoir or system. Over time, the sealing surface may degrade, causing a slow drip that wastes fluid and creates a mess. A cock drain that fails to seal fully may also let air enter the system, reducing efficiency. The item ships at approximately 0.02 pounds. Verify the serial number or application, then call (562) 693-7748.
