45B Fuel Dispenser Universal Joint(Multi-angle Rotating Joint for Fuel Nozzles)

A core dedicated accessory for gas stations, enabling flexible and durable connection between fuel dispenser hoses and nozzles via a **three-metal composite structure** (copper for threaded end + aluminum alloy for middle movable end + zinc alloy for rear end).

1. Materials & Core Advantages
- Threaded End (Pure Copper): Excellent conductivity for rapid static dissipation; wear-resistant and anti-slip, ensuring stable sealing/connection after repeated assembly.
- Middle Movable End (Aluminum Alloy): Lightweight with high strength, reducing operation fatigue; good corrosion resistance, free from rust caused by oil-gas or moisture.
- Rear End (Zinc Alloy): High structural strength for stable support; cost-effective with excellent impact resistance.

2. Technical Specifications
- Nominal Pressure: 0.2 MPa (≈29 psi)
- Thread Specification: 3/4″ (compatible with NPT/BSPT/G standards)
- Temperature Range: -20℃ ~ +60℃
- Rotation/Deflection: 360° radial rotation + 45° angular deflection (compact hinge, precise angle control).

3. Applications, Scenarios & Principle
-Core Function：Connects fuel dispenser hoses and nozzles; adapts to high-frequency, multi-angle refueling via the multi-metal composite’s "lightweight + weather resistance + conductivity".
- Applicable Scenarios：
- Busy urban stations: Aluminum alloy reduces handling fatigue; copper ensures static safety.
- Large temperature difference regions: Al-Zn alloy synergy resists embrittlement/softening for year-round stability.
- Cost-performance-focused stations: Zinc alloy controls cost; Cu-Al ensures key-component performance.
- Working Principle：
Copper threaded end: Conducts static + seals; aluminum alloy middle: 360° rotation/45° deflection to compensate deviations; zinc alloy rear: structural support. The three work together for safe static discharge, flexible operation, and durability.
