# Industrial Specification: Female Half

## 1. Technical Definition
The female component of a hydraulic quick coupler that receives the male half to establish a fluid connection.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-350 bar (0-35 MPa) hydraulic pressure, -40°C to 120°C temperature range**. Failure boundary: **Material yield strength exceeded at 450 MPa for steel variants, seal extrusion at 380 bar, surface hardness reduction below 58 HRC**, Mechanism: **Hertzian contact stress exceeding material fatigue limit at sealing interface, leading to micro-pitting and fluid leakage; thermal cycling causing differential expansion between steel body and elastomer seals**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding ISO 4406 18/16/13 cleanliness level | 8 | Seal abrasion and scoring of sealing surfaces causing 0.1 L/min leakage at 210 bar | Integrate 10 μm absolute filtration with beta₃≥200 rating in hydraulic circuit |
| Misalignment exceeding 0.5° angular or 0.2 mm radial offset during coupling | 8 | Asymmetric loading causing plastic deformation of locking mechanism at 150% rated pressure | Implement self-aligning spherical seat with ±3° compensation and visual alignment indicators |
