Heavy-Duty Filtration System

Lube/Oil Filter P550920

Essential Engine Core Protection & High-Efficiency Particle Isolation

Product Description

The Lube/Oil Filter P550920 provides essential engine core protection by isolating abrasive soot, fine wear metal flakes, and atmospheric dust before they can compromise precision internal oil films. Precision-engineered as a direct factory replacement for Donaldson P550920 and matching the exact original equipment requirements of Caterpillar 2698325, this robust unit is optimized for heavy-displacement engine platforms including the Caterpillar C6.6, C7.1 ACERT, and Perkins 1106/1200 series. It features a versatile engineering cross-reference profile across top global brands, matching Class 7988220, Doosan 40050400196, Hamm/Voegele 2050089, Massey Ferguson 4226293M1, and Perkins 4627133. Utilizing an advanced cellulose media structure laboratory-certified under rigorous ISO 16889 multi-pass guidelines, this filter achieves an outstanding 99% efficiency rating at 26 microns. Equipped with an integrated anti-drainback valve and dual-stage internal bypass valve limits (ranging from 30 psi to 37 psi), it ensures immediate full-flow lubricant circulation during cold-weather startups while mitigating high-viscosity restriction spikes under maximum mechanical load.

Product Advantages

■ 99% High-Efficiency Particle Isolation

Engineered with high-grade multi-pass cellulose media to extract 99% of microscopic 26-micron contaminants, protecting vital bearings, crankshaft journals, and valvetrains from friction-induced fatigue.

■ Dual-Stage Internal Bypass Valve Safety

Features precision-calibrated pressure relief safeguards (30 psi LR / 37 psi HR) to guarantee constant oil volume delivery to the engine block during high-viscosity cold starts or media saturation.

■ Integrated Anti-Drainback Control

Built with a highly resilient anti-drainback valve mechanism that maintains oil volume inside the filter housing when the equipment is shut down, completely preventing destructive metal-on-metal dry starts.
