Industrial Spin-On Lubrication Oil Filter
Heavy-Duty Fleet Protection | Part Identification: LF3854
LF3854 Product Description
This industrial spin-on lubrication oil filter is precision engineered to meet demanding oil cleanliness targets within high-load medium-duty commercial transport applications.,The canister features a heavy-gauge stamped steel outer shell housing an advanced pleated media matrix that ensures stable fluid passage during peak operational loads. Measuring an overall vertical height of 126.0 mm with an outer dome diameter of 123.0 mm, the unit relies on a robust 1"1/2-12UNF internal mounting thread for positive engagement. To protect cold-running engine blocks, the assembly integrates a precision-calibrated internal bypass valve that maintains oil flow if pressure spikes occur. A flat nitrile rubber gasket profile with a 112.0 mm tracking pattern ensures a secure, leak-proof seal against the engine mounting base.
LF3854 Core Technical Advantages
Optimized Full-Flow Filtration Media
Features a high-capacity pleated media layer designed to trap sub-micron soot, varnish particles, and metal shavings without restricting oil delivery channels.
Integrated Safety Bypass Assembly
Built with a precise internal bypass valve that ensures continuous oil flow to vital crankshaft bearings during cold-weather starts or media loading.
Thick-Walled Canister Architecture
Constructed using a rugged cold-rolled steel shell that easily resists high oil pressure spikes and road vibration without risking structural fatigue.
High-Torque Thread Engagement
Machined with an exact 1"1/2-12UNF mounting interface to prevent loosening under heavy engine thermal cycles and high-vibration logistics use.
