901662 Parker filter element

Product Description

901662 Parker Filter Element is specifically engineered for hydraulic pipeline systems,

 serving as a critical suction-line or pressure-line filtration component. It effectively removes metallic particles, 

sand grit, and colloidal contaminants from fluid media, significantly reducing equipment wear and failure risks. 

The element features a deep-bed pleated glass fiber medium, offering high dirt-holding capacity and 

low initial pressure drop, while the fully stainless steel end caps and center tube ensure structural

 integrity and consistent filtration performance under high-pressure surges and extreme temperature fluctuations.

 It is an ideal choice for safeguarding precision actuators and critical valves in hydraulic systems, ensuring long-term, 

trouble-free operation.

FAQ 

Q1: Is the 901662 filter element suitable for high-viscosity hydraulic fluids?

A: Yes. With a wide operating temperature range (-30℃~+110℃), the glass fiber media is insensitive to viscosity variations. 

However, for cold-start conditions, we recommend pre-heating the system to avoid instantaneous excessive

 differential pressure.

Q2: What is the recommended replacement interval for this filter element?

A: The replacement cycle depends on system contamination levels, operating environment,

 and target oil cleanliness. We recommend using a differential pressure indicator and replacing the element 

when the ΔP reaches 0.35–0.5 MPa, or following the maintenance schedule specified by your equipment manufacturer.

Q3: How do I choose the right filtration rating from 1 to 100 μm?

A: The selection should be based on the critical clearances of your system components 

(e.g., servo valves, proportional valves, pumps). High precision (1–10 μm) is suitable for precision servo systems; 

10–25 μm is common for general industrial equipment; and 50–100 μm is used for coarse filtration or return lines. 

Custom ratings are available upon request.

Q4: Can this filter element directly replace the original Parker 901662?

A: Absolutely. This product is manufactured strictly to Parker's original dimensions and performance standards. 

The external size, seal geometry, and filtration grade are fully interchangeable with the OEM version,

 meeting equivalent performance requirements with confidence.

Q5: Are there any installation precautions to keep in mind?

A: Yes. Ensure the system is depressurized and clean the filter housing interior before installation.

 Lubricate the O-ring with a small amount of working oil, and tighten the housing to the torque

 value indicated on the assembly – avoid over-tightening (which may damage seals) or 

under-tightening (which may cause internal bypass leakage).

Q6: Is the stainless steel frame corrosion-resistant?

A: Yes. Both the end caps and the center tube are made of stainless steel, providing excellent resistance to water, 

oil, and rust, making it suitable for humid environments or systems with high moisture content in the oil.
