Product Description
The 865891-4 is a hydraulic return line filter designed to remove particulates and contamination from aircraft fluid systems. It protects downstream pumps, valves, and actuators by capturing debris before hydraulic fluid re-enters the reservoir. This filter element uses a pleated media construction to maximize surface area while maintaining flow efficiency.
Installation follows the aircraft Maintenance Manual specifications, typically positioning the filter in the hydraulic return circuit. Verify applicability and service intervals in the aircraft Illustrated Parts Catalog before installation.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
