326-1643 diesel filter with high filtration accuracy and strong pollutant capacity-reduces equipment loss and is more worry free

326-1643 Caterpillar diesel filter is a key fuel system filtration component, efficiently intercepting impurities and water in diesel to protect injectors and fuel pumps, compatible with Caterpillar engine series. Ningbo Qiuning Trading Co., Ltd. offers original and aftermarket options: Original meets Caterpillar standards with high filtration accuracy; aftermarket passes tests with excellent cost-effectiveness, satisfying diverse needs.

Product Details

	326-1643 Caterpillar diesel filter plays a core filtration role in the fuel system. Through multi-layer composite filter materials (including glass fiber and resin-coated filter paper), it can intercept over 99.5% of particles larger than 10 microns and free water, preventing impurities from entering precision components such as injectors and fuel pumps, reducing wear and failure risks, and improving engine combustion efficiency.

	The diesel filter adopts a high-strength zinc alloy shell and nitrile rubber sealing ring, with a temperature resistance range of -30℃ to 80℃ and a pressure resistance of 10bar, compatible with Caterpillar 320D, 336D, 349D series excavators and C7.1, C9 engines. Its filtration flow reaches 80L/h, dirt-holding capacity is ≥15g, and the replacement cycle under normal working conditions is 500-800 hours, effectively extending the maintenance interval of the fuel system.

	As a professional supplier, Ningbo Qiuning Trading Co., Ltd. provides both original and aftermarket 326-1643 diesel filters. Original products strictly follow Caterpillar technical specifications, with filter materials and processes completely matching the original system, suitable for heavy-duty operations with extremely high requirements for filtration accuracy; Aftermarket products pass ISO 4020 standard tests, with filtration efficiency reaching over 95% of the original, and the price is only 60%-70% of the original, suitable for scenarios with limited budgets but requiring reliable filtration.

	We have sufficient inventory to enable global delivery within 48 hours, and our technical team can provide compatible model inquiry and installation guidance. Welcome to consult and purchase according to actual needs:
