Truck Mixer Products Filter Element P2.0933.02 RB31203003

This hydraulic filter element carries dual part numbers P2.0933.02 and RB31203003, made exclusively for concrete mixer truck hydraulic return oil circuits. It serves as a direct aftermarket replacement matching original mounting dimensions, fitting perfectly on mixer hydraulic tank filter housings without modification. It targets heavy-duty construction sites where constant tank rotation and road vibration expose hydraulic oil to metal shavings, sand and rubber debris.

Multi-layer folded glass fiber media forms the core filtration layer, delivering stable 10-micron absolute filtration efficiency. Deep pleat layout expands dirt holding capacity, extending service intervals under dusty job-site conditions. The media undergoes high-temperature resin curing to stop fiber shedding, avoiding secondary contamination of hydraulic pumps and drive motors during long haul mixing shifts.

Full perforated steel inner support sleeve and thick stamped metal end caps boost overall structural rigidity. The integrated NBR rubber seal locks tightly against filter housing seats to eliminate bypass leakage, even under frequent vehicle jolts and wide temperature swings. Built-in bypass valve activates once blockage hits set pressure, preventing system shutdown during unplanned filter replacement delays.

Designed to safeguard mixer truck core hydraulic assemblies including slewing reducer, drive motor and main pump. Clean oil maintained by this filter cuts premature gear and bearing wear, reducing costly breakdowns and roadside service downtime. It works well with standard 46# and 68# anti-wear hydraulic oil, adapting to year-round outdoor construction operation.

Each unit undergoes bubble point and flow fatigue testing before shipment to meet industry hydraulic filter standards. Compact cylindrical cartridge design allows quick single-person swap with no special tools required. Bulk stock available for mixer fleet maintenance shops, with consistent dimensional accuracy to guarantee interchangeability with original OEM filter parts.
