The P550848 Separator Filter is a precision‑engineered fluid management component designed for the fuel or hydraulic systems of SINOTRUK Howo heavy‑duty trucks, ensuring efficient separation of water, particulates, and contaminants. As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM‑grade separator filter as a direct replacement for the original factory unit. The P550848 separator filter delivers superior water separation and particulate removal, protecting sensitive system components from corrosion, wear, and premature failure, even under the most severe operating conditions.
Engineered with a high‑capacity coalescing media and a robust, corrosion‑resistant steel housing, the P550848 separator filter effectively removes water, dirt, and other contaminants from fuel or hydraulic fluid, ensuring clean, dry fluid circulates through the system. Its advanced design incorporates a sediment collection bowl with a convenient drain valve, allowing for easy removal of accumulated water and debris during routine maintenance.
OEM P550848 • Water separation • Coalescing media • Sediment bowl • Direct OEM fit
The P550848 is a premium separator filter designed specifically for SINOTRUK Howo trucks, commonly used in fuel or hydraulic systems to remove water and particulate contaminants. It is an essential component for maintaining fluid cleanliness, preventing corrosion, and ensuring the reliable operation of pumps, injectors, valves, and other precision components.
The P550848 separator filter incorporates a high‑efficiency coalescing medium that effectively separates water from the fluid stream, causing water droplets to coalesce and drop into the collection bowl. The bowl is transparent or translucent, allowing for visual inspection of water and sediment levels. A manual drain valve is provided for quick and easy removal of accumulated water and debris.
The filter element itself is constructed from high‑quality synthetic fibers that provide excellent particulate capture, removing particles down to 5 microns. The robust steel housing is internally coated to resist corrosion and is designed to withstand system pressures up to 15 bar, ensuring reliable performance in demanding applications.
Common symptoms of a clogged or water‑saturated separator filter include reduced system pressure, sluggish operation, water‑in‑fuel warnings, and accelerated component wear. Replacing the filter with the P550848 restores proper fluid separation, protects sensitive components, and extends fluid service life. This OEM‑spec filter is the ideal choice for preventative maintenance and system protection.
Whether you are servicing the fuel system of a long‑haul truck or maintaining the hydraulic system of a construction vehicle, the P550848 Separator Filter delivers the reliability, efficiency, and durability that SINOTRUK Howo professionals expect.
The P550848 separator filter is specifically designed for SINOTRUK Howo trucks equipped with fuel or hydraulic systems that incorporate a separator filter housing, including the widely used A7, T7H, and mixer chassis. It is a direct OE replacement and is fully compatible with factory filter heads and fluid connections.
This filter is essential for applications where water and particulate contamination are common, such as long‑haul transport, construction, mining, and agriculture. In these environments, fuel or hydraulic oil can become contaminated with water from condensation, storage, or washdown, leading to corrosion, pump wear, and injector sticking. The P550848 provides the separation and filtration needed to maintain fluid cleanliness and system reliability.
When replacing the separator filter, it is recommended to inspect the housing, drain valve, and sealing surfaces for any damage or debris. The P550848 is compatible with diesel fuel, biodiesel blends (up to B20), and various hydraulic fluids, offering versatility for fleet operators.
For fleets with multiple Howo trucks, standardizing on the P550848 simplifies inventory management and ensures that the correct filter is available for scheduled services. Always verify the filter thread and dimensions on your specific truck to confirm compatibility, though the P550848 is the standard separator filter for most Howo heavy‑duty models.
Replacing the P550848 separator filter is a straightforward procedure that can be performed by most technicians using standard hand tools. Begin by relieving system pressure (if applicable) and placing a suitable container under the filter to catch any spilled fluid.
Remove the old filter by turning it counterclockwise with a filter wrench. Clean the mounting surface on the filter head, ensuring the old gasket is completely removed. Apply a thin film of clean fluid to the new filter’s gasket to ensure a proper seal. Screw the new P550848 filter onto the head until the gasket contacts the sealing surface, then tighten an additional ¾ to 1 full turn (or to the manufacturer’s torque specification of 18‑22 Nm).
After installation, top up the fluid level and start the engine (or operate the hydraulic system) to purge air and check for leaks around the filter. If the filter has a drain valve, open it briefly to ensure it is functioning and to remove any air from the bowl.
For maintenance, replace the separator filter at every recommended service interval, typically every 1,000 operating hours or annually, whichever comes first. In applications with high water contamination, more frequent replacement may be necessary. Regularly inspect the collection bowl for water accumulation and drain as needed. A visual check of the bowl can indicate when the filter needs changing. Keep a log of filter changes to track maintenance schedules and identify trends in fluid contamination.
The P550848 separator filter is manufactured in an ISO 9001‑certified facility using advanced coalescing media technology and precision assembly processes. The synthetic fiber media is sourced from leading global suppliers and is tested for efficiency, water separation performance (SAE J1488), and dirt‑holding capacity. The steel housing is formed from high‑grade steel and coated with a durable anti‑corrosion layer.
Each filter undergoes rigorous quality control checks, including media integrity testing, water separation verification, burst pressure testing, and leak testing under vacuum and pressure. Random samples from each production batch are subjected to endurance testing on a fluid system test bench to validate filtration performance, pressure fatigue resistance, and structural durability over the filter’s service life.
We back the P550848 with a comprehensive 12‑month warranty against material and workmanship defects. Our commitment to quality ensures that every filter delivers the same level of protection and performance as the original equipment, giving you confidence in your fluid system’s reliability.
