High-Pressure Hydraulic Purification Element
PT676 HYDRAULIC FILTER
PREMIUM MEDIA
"
Designed for uncompromising system protection, the PT676 hydraulic filter element is meticulously fabricated utilizing advanced micro-glass media to capture silent killers like fine silt, carbon soot, and metallic wear debris. Industrial hydraulic loops operate under punishing multi-phase cycles and intense fluctuating pressures, rendering reliable fluid purification paramount to prevent abrasive internal wear and unexpected valve stiction. This filter delivers an exceptional Dirt Holding Capacity (DHC) paired with an engineered low initial pressure drop, maintaining stable flow characteristics and high beta ratios even during freezing cold starts. By controlling fluid contamination according to strict international ISO cleanliness metrics, it preserves systemic stability, minimizes mechanical friction, and significantly extends the service life of heavy-duty components operating within volatile mining, heavy logistics, construction, and global material handling industries.
Product Usage Instructions
01
Complete Isolation
Securely shut down the heavy machinery, fully depressurize the entire hydraulic circuit via the auxiliary control valves, and meticulously clean the external surfaces of the filter housing to eliminate any chance of atmospheric dust or dirt migrating into the clean side of the system.
02
Extraction and Inspection
Carefully unscrew the housing cap, extract the saturated element without tilting, inspect the internal sediment cavity for signs of unusual mechanical wear, and verify that the spent sealing rings are fully removed.
03
Seal Lubrication
Coat the new premium Nitrile rubber seals with a thin, uniform layer of clean, fresh operational hydraulic oil to prevent binding, structural twisting, or dry frictional shearing during the final reassembly phase.
04
Correct Torque Seating
Place the replacement element firmly over the alignment guide, thread the housing enclosure back into position, tighten to the machine manufacturer's precise torque specification using a calibrated wrench, run the machine to purge air, and inspect for micro-leaks.
