45A universal joint

45A Fuel Dispenser Universal Joint (Also known as 360° Rotating Fuel Nozzle Joint)

Core gas station component – connects fuel dispenser hoses to nozzles, sight glasses, and other pipeline parts.

1. 2 Material Options
- Zinc Alloy + Brass
Main body: Oil-gas corrosion-resistant, high-strength; Threaded end: Good conductivity, wear-resistant, stable sealing after assembly/disassembly; Seals: NBR/fluororubber (fuel-proof, leak-free).
- 304 Stainless Steel
Full 304 structure: Stronger corrosion resistance (fits humid/high-salt-fog/chemical areas); Better temperature/wear resistance, 30%+ longer lifespan; Seals: NBR/fluororubber.

2. Key Technical Specs
- Nominal Pressure: 0.18 MPa (≈26 psi)
- Threads: 3/4″, 1″ (compatible with NPT/BSPT/G)
- Temp Range: Standard: -25℃~+55℃; Low-temp: -40℃~+55℃
- Rotation: 360° radial + 45° angular (all versions)

3. Uses, Scenarios & Working Principle
- Uses & Scenarios
Core: Prevents hose twisting/wear; dissipates static via metal.
- Zinc Alloy + Brass: For standard stations (urban/highway, cost-effective).
- 304 Stainless Steel: For special areas (coastal, chemical, frigid/humid).
- Working Principle
2-piece hinged structure:
1. Rotation/deflection compensates for hose-nozzle deviation (avoids leaks).
2. Conductive metals (zinc alloy+brass/304 stainless steel) dissipate static safely (stable even in harsh environments).
