# Industrial Specification: Sealing Head

## 1. Technical Definition
A precision component that creates an airtight seal against beverage containers during pressure testing.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-12 bar**. Failure boundary: **15 bar (material yield strength) or 0.1 bar (seal detachment pressure)**, Mechanism: **Elastomer compression set exceeding 25% permanent deformation at 70°C, or seal lip tensile failure at 15 MPa stress**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
