LFP440F Spin-On Fuel Filter

Technical Specifications

Engineering Mechanics & Material Architecture

High-Capacity Synthetic Media

Features a pleated synthetic cellulose media matrix designed to retain fine abrasives, rust scale, and organic contaminants, maintaining stable fuel flow velocity during continuous engine load.

Heavy-Duty Canister Shell

Encased in a cold-rolled steel housing designed to withstand continuous fuel supply pressure surges and external mechanical vibration without structural deformation.

Precision Thread & Gasket Sealing

Precision-machined 1"-14 UNF mounting threads paired with a high-durometer elastomeric seal ring ensure an airtight interface, preventing external fuel leakage and air ingress into the injection circuit.

Worksite Hazards & Protection Strategies

Severe Mining & Excavation Duty

Site Hazard: Airborne dust, contaminated bulk storage fuel, and heavy equipment vibration.

Protection Strategy: Filters particulate matter before raw diesel reaches high-pressure pumps, reducing plunger wear and preventing injector tip erosion.

Commercial Transport & Refrigeration Logistics

Site Hazard: Continuous long-haul running conditions and variable ambient fuel temperatures.

Protection Strategy: Maintains steady fuel pressure delivery, shielding engine fuel rails and preventing unexpected engine stalling or power loss.

Field Maintenance Protocol

Installation Sequence

• ■Drain & Remove: Unscrew the degraded filter element using a standard strap wrench and properly dispose of residual fuel.
• ■Thread & Seal Check: Clean the mounting header surface and apply a light coat of clean engine oil to the new rubber gasket.
• ■Hand Tighten: Spin the new LFP440F filter onto the header until the seal contacts the baseplate, then tighten an additional 3/4 to 1 turn by hand.
• ■Prime & Leak Test: Prime the fuel system to purge air pockets, start the engine, and inspect for fuel seal integrity.

Service Threshold Indicators

• ■Unstable engine idling or hesitant acceleration under heavy load.
• ■Reduced fuel pressure delivery at high engine operating speeds.
• ■Scheduled fleet maintenance intervals (per OEM service guidelines).

Custom Manufacturing & Supply Services

B2B Private Labeling & OEM Branding

• ■Custom Marking: Laser engraving or screen printing of part codes, batch numbers, and buyer logos directly on the canister housing.
• ■Packaging Solutions: Individual poly-bag protection, custom branded inner cartons, and palletized ocean freight preparation.
