P551604 Full-Flow Spin-On Lube Oil Filter for Fiat, Iveco Trucks, Fiatallis
Product Overview
The Donaldson P551604 Spin-On Full-Flow Lube Filter is a heavy-duty engine lubrication component designed to maintain peak oil purity and continuous lubrication in demanding industrial, construction, agricultural, and commercial transportation engines. Built according to SAE J1858 testing standards, it features high-density cellulose filtration media, precise 1-12 UN mounting threads, and integrated bypass valves (1.3 / 1.4 bar setting). The P551604 reliably captures carbon deposits, soot, wear metals, and contaminants to prevent engine friction and extend equipment service life.
Key Advantages
- Full-Flow Engine Protection: High-capacity cellulose media provides continuous 100% oil filtration, meeting SAE J1858 standards for high particle separation efficiency.
- Built-in Dual Bypass Protection: Dual bypass valve setting (1.3 bar LR / 1.4 bar HR) ensures continuous oil supply to critical engine components during cold starts or high pressure drops.
- High Burst Strength Canister: Robust steel spin-on housing delivers a collapse/burst pressure resistance of up to 6.9 bar, preventing casing deformation under pressure surges.
- Precision 1-12 UN Threading: Factory-machined thread interface guarantees an airtight, leak-resistant fit and easy spin-on replacement.
- Broad Engine & Equipment Fitment: Compatible with a wide range of diesel engines including Fiat 8205/8215/8365, Iveco, MWM, and Perkins power units.
