Parker Filter Replacement | 940803 | 937406Q | 937407Q Hydraulic Element | Microglass Filtration

High-Performance Replacement Hydraulic Filters for Parker Series

Product Overview:

This series of filter elements is specifically engineered as premium replacements for Parker hydraulic filters, featuring core models 940803, 937406Q, and 937407Q. In the high-intensity industrial environments of 2026, hydraulic systems demand unprecedented fluid cleanliness. These elements utilize advanced inorganic microglass pleated technology to provide comprehensive wear protection for hydraulic pumps, motors, and proportional valves.

Featured Models: 940803, 937406Q (High-Performance Q-Class), and 937407Q (High-Performance Q-Class).

Key Technical Advantages:

• High-Efficiency Q-Class Microglass: Models with the “Q” suffix (e.g., 937406Q) feature patented microfiber technology. With an exceptional beta ratio of $\beta_x(c) \ge 1000$, they precisely intercept micron-level contaminants, maintaining stable ISO 4406 cleanliness levels.

• Deep Pleated Dirt Loading: Scientifically optimized pleat density significantly increases the effective filtration area. This reduces the initial system pressure drop and provides superior Dirt Holding Capacity, substantially extending maintenance intervals.

• Heavy-Duty Support Core: Featuring a high-strength galvanized inner core with excellent collapse resistance, these elements remain structurally sound even during high-viscosity cold starts or sudden flow surges, preventing media failure.

• Precision Physical Compatibility: Manufactured strictly to OEM physical tolerances, ensuring end cap dimensions and seal placement are a $100\%$ match with the original housing. This eliminates bypass and achieves zero-leakage filtration.

• Multi-Medium Compatibility: Suitable for mineral oils, synthetic lubricants, and anti-rust fluids. Equipped with high-grade NBR seals to maintain flexibility under continuous thermal stress.
