The SWCQ-A25×80 hydraulic oil filter element is a high-performance replacement filter cartridge designed specifically for Leemin dual-tank lubricating oil filtration systems. This filter element is the core consumable component used within SWCQ series duplex filters, commonly found in thin oil lubrication systems for industrial machinery and power generation equipment.
The SWCQ-A25×80 hydraulic filter cartridge is installed at the oil pump outlet or upstream of the cooler within the lubrication system, where it continuously removes mechanical impurities, metal wear debris, rubber particles, and other contaminants from the hydraulic fluid and lubricating oil. By maintaining the cleanliness of the working medium, this replacement hydraulic oil filter cartridge helps protect downstream equipment such as pumps, valves, bearings, and hydraulic actuators from premature wear and failure.
SWCQ-A25×80 replace Leemin hydraulic oil filter elements are manufactured and tested according to international standards to ensure quality and reliability.

At Huahang Filter, we recognize that standard replacement parts are not always the perfect fit. We offer a robust Custom Service to tailor the filters to your specific needs . If you require a variation from the standard model, we can engineer it.
Custom Dimensions: Need a different length, outer diameter, or inner diameter to fit a non-standard housing? We can modify the core structure to meet your space constraints .
Custom Filtration Ratings: Choose from a range of filtration efficiencies from 1μm to 100μm to achieve your desired cleanliness levels .
Custom Packaging: From bulk packaging to individual retail boxes, or specific labeling requirements for OEM projects, we can customize the packaging to suit your inventory and branding needs .
Custom End Caps: We can manufacture alternative end cap configurations or materials (stainless steel, aluminum, reinforced nylon) to ensure the element seals correctly in various housing designs .
Custom Filter Media: Choose from a variety of media types, including microfiber glass, stainless steel wire mesh, stainless steel sintered mesh, cellulose, or synthetic blends, to achieve different filtration efficiencies, dirt-holding capacities, or chemical compatibilities .
Special Seal Materials: In addition to standard NBR (Nitrile), we offer seals in Viton (FKM) , EPDM, or Silicone to handle aggressive fluids or extreme temperatures

Q: How is this different from the OEM Leemin filter?
A: Huahang’s element is manufactured to meet or exceed the original Leemin specifications for filtration efficiency, dirt-holding capacity, pressure drop, and dimensional accuracy. The difference is price and availability. Huahang’s factory-direct pricing is significantly lower, and lead times are often shorter.
Q: What filtration efficiency can I expect?
A: The glass fiber media provides βₓ ≥ 100 for the specified micron rating, which means at least 99% of particles at or above the rated size are captured in a single pass through the element. Multi-pass testing per ISO 16889 confirms performance.
Q: Do you ship internationally?
A: Yes. Huahang ships worldwide via air freight, sea freight, and express couriers (DHL, FedEx, UPS). Delivery times vary by destination and quantity.
Q: How do I install the element correctly?
A: Installation steps: Shut down the hydraulic system and relieve all pressure. Remove the filter housing cover. Carefully remove the old element. Clean the housing interior. Install the new element with new seals if included. Reinstall the housing cover and tighten to the torque specified in your equipment manual. Restart the system and check for leaks.
