Basic Components
1.Housing body: usually aluminum alloy or cast iron, with strength and oil resistance
2.Sealing ring/O-ring: Ensure no leakage between the filter element and the housing
3.Filter element connection seat: threaded interface or slot type, fixed filter element
4.Oil inlet/oil outlet: threaded or flange port
5.Bypass Valve: Ensure the lubricant flow bypasses when the filter element is blocked
6.Engine oil cooler interface: integrated water-cooled or plate-fin oil cooler connection
7.Sensor interface: Pressure or temperature sensor mounting hole
Specifications
Material: aluminum alloy (Al6061, Al6082), gray cast iron, engineering plastic (some for automobiles)
Maximum operating pressure: 0.6–1.0 MPa (6–10 bar), up to 25 bar for some hydraulic systems
Working temperature range: -40℃ ~ +150℃, oil temperature of some models can reach 170℃
Import and export dimensions: M18×1.5, M22×1.5, 3/4"-16UNF, 1"-12UNF, G1/2, G3/4
Adaptive filter element type: Spin-on, Cartridge
Filter element length/diameter: Common filter element height 100–250mm, diameter 60–120mm
Installation method: flange installation, thread installation, bottom support fixation
Oil-cooled interface size: M12/M14, quick plug connector, water-cooled interface (Ø8~Ø12mm)
Advantages and Features
Fixed filter element: Provides a sealed cavity to accommodate the filter element
Conducting oil circuit: Connect the oil inlet and oil outlet to form an oil circulation path
Integrated cooling/temperature control device (part): Integrated oil cooler or constant temperature valve
Filtration status monitoring: Some housings have pressure sensor interfaces
Bypass and check function: prevent oil-free operation during blockage and avoid reflux
Application Scenarios
Internal combustion engine oil system (automotive, truck, motorcycle, ship)
Hydraulic equipment (hydraulic stations, industrial machinery)
Generator set
Compressor lubrication system
Automatic transmission oil filter system
Select Suggestions
Filter element type matching: Confirm the filter element is Spin-on or Cartridge.
Oil circuit pressure and temperature: If used in high-pressure systems, it is recommended to use cast iron or steel shells.
Is a cooling interface required: High-performance or heavy-load engines should choose a housing with a cooler integrated interface.
Size and installation space: Ensure that the installation space supports housing size and filter element removal and replacement.
Whether to bring bypass valve: It must be equipped with reliable bypass protection to prevent dry friction.
