The Purolator Facet 1742510 Filter Element Kit (often designated as 1742510-01) is a high-efficiency, aerospace-grade micro-porous hydraulic filter element manufactured by Purolator Facet, Inc. Engineered specifically for high-pressure aircraft hydraulic systems, actuation assemblies, and fluid power loops, the 1742510 filter element protects delicate hydraulic valves, pumps, and flight control actuators by capturing microscopic particulate contamination. Supplied as a complete service kit including replacement O-rings, it maintains low differential pressure and high particulate holding capacity under extreme thermal and pressure cycling environments commonly encountered in commercial and military aviation MRO operations.

Approved Specifications & Aviation Conformance:

Purolator Facet 1742510 filter elements meet rigorous aviation quality baselines and airframe manufacturing standards:

• FAA-PMA Approval: Certified under Federal Aviation Administration Parts Manufacturer Approval (FAA-PMA) for direct airframe replacement.
• ISO 16889 Multi-Pass Tested: Verified for high beta ratio filtration efficiency and particulate retention capability under fluid flow fatigue.
• Fluid Immunity: Non-reactive construction immune to chemical breakdown caused by synthetic fire-resistant hydraulic fluids.

Key Features & Performance Benefits

• Superior Contaminant Retention: High-density pleated media maximizes surface area, capturing metallic wear particles, silt, and carbon particulates down to low micron levels.
• Low Differential Pressure Drop: Optimized pleat spacing allows high fluid flow rates with minimal initial resistance, reducing energy loss in hydraulic power packs.
• High Collapse Resistance: Built with an internal perforated stainless steel support core to withstand high differential pressure spikes without element collapse.
• Complete Servicing Kit: Includes pre-packaged elastomer O-rings to ensure a leak-free, rapid housing seal during scheduled maintenance intervals.
• Exceptional Structural Integrity: End caps and outer wraps resist mechanical shock, high-frequency vibration, and fluid surge pressures.

Typical Applications

• Aircraft Hydraulic Systems: Main filtration element for primary and secondary flight control hydraulic power supply units.
• Landing Gear & Actuation Maintenance: Protects landing gear retract/extend mechanisms, brake valves, and thrust reverser actuators from particle scoring.
• Ground Support & MRO Equipment: Used in hydraulic test benches, ground power carts, and flush carts servicing aviation fluid loops.

At Aircraft Shop Supply, we are committed to shipping the highest quality and freshest product possible. To ensure efficient stock rotation and meet aviation industry standards, our inventory management is governed by the following policy:

1. Scope of Application
All Sales Channels: This policy applies to all orders processed by Aircraft Shop Supply, including but not limited to: website purchases, direct email orders, formal Purchase Orders (POs), phone orders, and contract agreements.

2. Inventory Management (FIFO)
All products with an expiration date are managed and shipped on a strict "First In – First Out" (FIFO) basis.

3. Minimum Shipping Margin
Standard Guarantee: We will not ship any products with fewer than 30 days of use remaining (days before expiration), unless previously coordinated and agreed upon with the customer.

No Automatic Guarantees: Outside of this 30-day minimum margin, Aircraft Shop Supply does not make any automatic guarantee as to the specific length of time remaining on any shelf-life item for standard orders.

4. Special Customer Requirements
We understand that certain projects, maintenance schedules, or regulatory standards require strict specifications. If your order has specific shelf-life requirements, please proceed as follows:

How to Request: If you require a specific Date of Manufacture (DOM), Date of Expiration (DOE), or a specific minimum shelf-life percentage (%), you must clearly state this requirement:

In the Comments/Notes section when placing an online order.

Explicitly written on your Purchase Order (PO) or quote request email for offline orders.

Validation Process: Once your requirement is received:

We will ship your order if the available stock matches your specifications.

If we do not have the exact batch, we will contact you prior to shipping with the shelf-life percentage (%) or dates we have available for your acceptance.
