Weichai WP10H WP12 lube filter

611600070119 OEM Long Life Engine Oil Filter  611600070119 is an OEM standard long-life cartridge oil filter paper core, interchangeable with part number 611600070065, specially customized for Weichai WP7, WP10H, WP12 series heavy-duty diesel engines, widely matched for FAW Jiefang Han V375 heavy trucks. As the core protection component of the engine lubrication system, this high-density pleated paper core efficiently captures metal wear debris, carbon sludge, oxide residue and fine dust suspended in circulating engine oil during long-hour heavy-load transportation and engineering operation. It keeps lubricating oil continuously clean, maintains stable oil pressure for crankshafts, bearings, pistons and camshaft assemblies, effectively avoiding abrasive scratches and premature wear of precision internal engine parts. Manufactured strictly in accordance with original Weichai OEM dimensional standards and IATF16949 automotive quality certification, this upgraded long-service filter reduces engine abnormal noise, excessive oil consumption and unexpected mechanical failures, greatly extending overall engine service life. Every finished paper core passes strict burst pressure, high-temperature endurance and multi-pass filtration efficiency tests compliant with ISO 16889 standards. We provide abundant spot stock, neutral export packaging & private label customization and a 12-month quality warranty, which is a cost-effective aftermarket spare part for global heavy truck parts wholesalers, professional repair service centers and large logistics & construction fleet maintenance teams.  Product Material Description: Filter Media: Imported multi-layer gradient composite full-adhesive fiber filter paper, with uniform stable micropores, ultra-large dirt holding capacity, excellent high-temperature resistance and sustained stable precision filtration under sustained heavy engine operating temperature. Matching Sealing O-Ring: Premium NBR nitrile butadiene rubber gasket included, resistant to high-temperature engine oil corrosion, low-temperature hardening and aging deformation, realizing full tight sealing to eliminate oil bypass and leakage completely. Upper & Lower Reinforced Plastic End Caps: High-strength integrated injection molded plastic end covers, rigid structure that resists deformation and cracking under long-term fluctuating internal oil pressure impact. Internal Central Support Skeleton: Molded reinforced plastic central tube, firmly supports the pleated filter paper core to avoid collapse and distortion caused by instantaneous high oil flow pressure.
