Parker 931018Q Hydraulic Filter Element 20 Micron

Product Description

The PARKER 931018Q is a hydraulic filter element designed to remove oil contaminants from hydraulic fluid systems. Constructed from microglass filter media, this element delivers a 20-micron filtration rating for reliable particulate capture in demanding fluid power applications. It measures 1.6 inches inside diameter and 4.0 inches outside diameter, making it a compact, direct-fit replacement in compatible filter housings. Hydraulic system technicians and fluid power specialists install this element during scheduled maintenance or when filter differential pressure indicators signal a change is needed. The microglass construction supports consistent flow while maintaining filtration efficiency across operating cycles.

This filter element is suited for use in industrial and mobile hydraulic systems where oil contamination control is critical to component longevity. Typical applications include hydraulic power units, presses, injection molding machinery, and mobile equipment hydraulic circuits. The 931018Q serves as a cross-reference replacement for elements from multiple manufacturers, making it a practical stock item for shops that service mixed-brand hydraulic equipment. It is sold individually and is appropriate for both routine filter change intervals and corrective maintenance situations.

Key Features

• 20-micron filtration rating for effective oil contamination removal
• Microglass filter media construction for consistent particle capture and flow performance
• 1.6-inch inside diameter and 4.0-inch outside diameter for direct housing fitment
• Cross-references multiple OEM part numbers across major hydraulic filter brands
• Single-element packaging suits both unit replacement and low-volume stocking

Compatibility

The PARKER 931018Q is a direct replacement for Hydac part number HK-020BN, Hycon part number HK-020BN, PTI part number HF4-050-JF-B, Pall part number HC9700FKT9H, and Vickers part number V4051V3C20. Verify housing dimensions and connection type against the 1.6-inch ID and 4.0-inch OD before installation.

Installation Notes

Installation is performed by a qualified hydraulic technician. Always depressurize and de-energize the hydraulic system fully before opening any filter housing. Dispose of used elements and drained fluid in accordance with local environmental regulations. Inspect housing O-rings and seals at each element change and replace as needed to prevent bypass leakage.
