Komatsu 07030-00252 Breather Assembly

The 07030-00252 breather is a screw-in type ventilation component designated as P60, engineered to maintain atmospheric pressure equilibrium within hydraulic reservoirs and fuel systems on Komatsu construction machinery. It prevents ingress of airborne contaminants and moisture while allowing bidirectional airflow during fluid level changes. Constructed with a metal housing and integrated filter element, this disposable breather installs directly onto the hydraulic tank or radiator sub-tank neck. It serves as a direct OEM replacement for Komatsu part number 07030-00252 and crosses to HiFi Filter FS 127. Verified compatibility includes S6D140E, SA6D140E, and SAA6D140E diesel engines powering D135A-1, D135A-2, D150A-1, D155A-1, and D155A-2 crawler dozers.
