As core precision components of hydraulic systems, hydraulic fittings tend to retain contaminants such as processing oil, iron filings and polishing dust inside their threads, micro-holes, blind holes and inner walls. These residues are the primary cause of hydraulic system stalling, leakage, component abrasion and shortened service life. Conventional water washing and simple spray cleaning fail to thoroughly clean hidden crevices, deliver uneven drying and leave parts prone to rusting with inconsistent cleanliness, which cannot meet the assembly and operation standards of high-end hydraulic equipment. To address these industrial pain points, Bakr has developed a precision vacuum hydrocarbon cleaning solution specially designed for mass cleaning procedures of hydraulic fittings.

Centered on core equipment including vacuum hydrocarbon cleaning machines, modified alcohol cleaning machines and vacuum ultrasonic cleaning machines, this solution integrates composite processes of ultrasonic cavitation stripping, targeted spray flushing and vacuum enclosed descaling. It completely removes micron-sized contaminants on the surface, inside micro-holes and within thread gaps of hydraulic fittings, eliminating the blind spot residue issue plaguing traditional cleaning methods. The equipment operates in a fully enclosed cycle with eco-friendly dedicated cleaning solvents that can be recycled via distillation, drastically cutting consumable costs and pollution emissions to realize low-consumption eco-friendly production.

Equipped with an automatic low-temperature vacuum drying system, the integrated unit completes washing, rinsing and drying in one go, eliminating water stain residues and oxidative rust to fully preserve the dimensional accuracy and surface quality of hydraulic fittings. The stable process consistently achieves high-tier NAS cleanliness standards, suiting mass cleaning of all types of products including high-pressure hydraulic fittings and precision hydraulic tubes. Furthermore, the equipment can be seamlessly connected to automatic production lines for large-volume manufacturing, greatly boosting cleaning efficiency and cutting labor costs. It delivers reliable cleanliness assurance for hydraulic component assembly and finished machine delivery.
