1002166148 Fuel Pre-Filter Paper Core The 1002166148 paper core is an OEM-grade primary fuel pre-filter inner element specially designed for Weichai WP6H and WP7 Euro VI electronic common rail diesel engines, perfectly matched for mainstream domestic heavy-duty commercial trucks and construction machinery. Manufactured strictly in accordance with IATF 16949 automotive quality system standards, this deep-pleated composite filter paper core adopts imported gradient-density Ahlstrom filter paper medium, which can efficiently intercept large sediment, rust particles, coarse solid contaminants and free water mixed in diesel fuel at the primary filtration stage. It greatly reduces the impurity load for the fine filter at the rear end, fully protecting high-pressure fuel pumps, precision injectors and core engine fuel system components from abrasive wear and water cavitation damage. Rigorously tested to withstand long-time high-load highway operation, severe off-road vibration, high-temperature engine bays and low-temperature frigid working environments, this filter core maintains stable and consistent primary filtration efficiency during its full service cycle. With precise OEM dimensional molding, it supports direct plug-and-play installation on matched filter housings without modification, serving as an essential daily maintenance consumable for domestic and overseas logistics fleets, freight transportation companies, construction and mining machinery operation teams.
Product Material Description:
Main Filter Medium: Premium imported Ahlstrom HV composite wood pulp filter paper, with uniform stable pore structure, excellent coarse dirt holding capacity and outstanding hydrophobic water separation performance for heavy-duty primary filtration work.
End Cap Structure: Reinforced rigid black engineering plastic upper and lower end caps with positioning buckles, high structural rigidity to resist deformation and collapse under frequent fuel pressure fluctuations.
Sealing Components: High-grade HNBR nitrile rubber sealing gaskets, with excellent oil resistance, wide working temperature range (-40℃ ~ 130℃) and superior anti-ageing performance to achieve complete leakproof sealing.
Bonding Adhesive: Environmentally friendly high-temperature oil-proof hot melt adhesive, which firmly laminates multi-layer filter paper tightly, and will never dissolve or peel off after long-term immersion in standard diesel fuel.
