High-Performance Replacement Hydraulic Filters for Parker Series

Product Overview:

This series of filter elements is engineered as a premium replacement for Parker hydraulic filters, widely used in industrial power units, construction machinery, and precision lubrication systems. In the demanding industrial environments of 2026, models such as 937405Q and 932670Q utilize advanced Microglass media to provide top-tier wear protection for hydraulic pumps, servo valves, and actuators, ensuring systems operate at ideal cleanliness levels.

Featured Model Matrix:

• 937xxx Series: 937405Q, 937406Q, 937407Q, 937398Q

• 932xxx Series: 932670Q, 932669Q, 932612Q, 932610Q

• Standard Series: 940803

Key Technical Advantages:

• High-Efficiency Q-Class Technology: Models with the “Q” suffix (e.g., 937406Q) feature patented multi-layer Microglass media with an exceptional beta ratio of $\beta_x(c) \ge 1000$, improving retention of fine particles by over 40% compared to standard media.

• Deep Pleated Capacity: Precision pleating technology maximizes the effective filtration area, delivering massive Dirt Holding Capacity while maintaining a low initial pressure drop, significantly extending service intervals.

• Pressure Shock Resistance: Equipped with thickened galvanized center cores for superior collapse resistance. The structural integrity remains secure even during high-viscosity cold starts or frequent pressure fluctuations.

• $100\%$ Physical Interchangeability: Manufactured strictly to OEM dimensional tolerances with high-grade NBR or Viton seals, ensuring a $100\%$ leak-proof fit with the filter housing.

Detailed Specifications:

• Filtration Ratings: $2\mu\text{m}, 5\mu\text{m}, 10\mu\text{m}, 20\mu\text{m}$ (model dependent).

• Filter Media: Composite Microglass / High-strength Cellulose.

• Operating Temperature: $-30^\circ\text{C}$ to $+120^\circ\text{C}$.

• Compatible Mediums: Anti-wear hydraulic oils, synthetic lubricants, water-glycols, and oils.
