Original Cummins engine auto parts oil filter ZPC4389022

Built as the first line of defense for the X15/ISX15’s high-performance lubrication system, this oil filter adopts an advanced multi-layer filtration media design. The primary layer is a 15μm micro-glass fiber membrane with electrostatic adsorption technology, capturing 99.9% of particles as small as 3μm—including metal shavings from piston rings, carbon deposits from combustion, and dust ingress. A secondary cellulose layer enhances dirt-holding capacity to 28g, 50% higher than aftermarket filters, allowing extended service intervals of 30,000km for long-haul applications. A tertiary synthetic mesh layer reinforces structural stability, preventing media collapse even under 600kPa oil pressure surges during cold starts

Engineered to endure the harsh operating conditions of heavy-duty engines, the ZPC4389022 filter features a rugged, industrial-grade structure. The housing is crafted from cold-rolled steel (ST37-2) with a 2.5mm wall thickness, undergoing powder coating for corrosion resistance and achieving a burst pressure rating of 1200kPa—far exceeding the X15 engine’s maximum oil pressure of 500kPa. The internal filter core is supported by a galvanized steel skeleton, resisting deformation from engine vibration (10-2000Hz) during off-road or construction site operations. A reinforced hexagon base (80mm) ensures easy installation and removal with standard tools, even after long-term exposure to 150℃ engine temperatures

The oil filter integrates two critical functional designs to maintain continuous engine protection. A precision-calibrated bypass valve (set at 150kPa) opens automatically when the filter is clogged (e.g., due to extended service), ensuring oil flow to critical components like the crankshaft and camshaft—preventing oil starvation and catastrophic engine damage. An anti-drainback valve (made of FKM rubber) creates a tight seal when the engine is shut down, retaining oil in the filter and oil lines. This eliminates dry starts, reducing initial wear on bearings by 70% and extending their service life to ≥300,000km. The valve operates reliably across a temperature range of -40℃ to 180℃, adapting to extreme climates

The ZPC4389022 filter delivers significant cost savings and reliable performance in diverse environments. Its extended service interval (30,000km vs. 15,000km for aftermarket filters) reduces maintenance frequency by 50%, lowering labor costs for fleet operators. By capturing 99.9% of contaminants, it extends the life of engine oil by 30% and reduces the risk of expensive overhauls (costing up to $15,000). The filter’s powder-coated housing and galvanized components pass 2000-hour neutral salt spray testing (ASTM B117), resisting rust in coastal or saline-alkali areas. Backed by a 2-year/30,000km Cummins warranty, it ensures compliance with engine maintenance requirements and minimizes unplanned downtime—critical for time-sensitive logistics and heavy-duty operations
