Swivel Barb Fitting

Swivel Barb Fitting (For Gas Station Large-Diameter Nozzle-Hose Connection)

Core Differentiation: Made of copper + aluminum alloy composite material, with two sizes (1.5", 2") and an integrated 360° no-dead-angle swivel design — distinguishing from ordinary barb fittings with “split structure, rotation jamming, and poor adaptability”. It is engineered for large-diameter (1.5", 2") nozzle-hose connections in gas stations, featuring no-disassembly installation, reliable sealing, and superior swivel performance.

1. Performance & Specifications
- Size Specifications: 1.5", 2";
- Material Combination: Copper (thread end, for strong sealing) + aluminum alloy (barb end, lightweight and fuel-corrosion resistant);
- Thread Types: NPT, BSP (compatible with mainstream dispenser thread standards);
- Working Parameters: Operating temperature -30℃~80℃, 360° no-dead-angle swivel, and leak-proof sealing.

2. Working Principle, Scenarios & Usage
- Working Principle:
The integrated structure houses internal swivel components, enabling 360° free rotation between the barb end and copper thread end. During refueling, the hose rotates flexibly (no dead angles) with operation, while the copper-aluminum composite material ensures robust thread sealing and impact resistance of the barb end.
- Application Scenarios:
Used between 1.5" and 2" diameter nozzles and oil hoses in gas stations, ideal for large-diameter fuel pipelines requiring high swivel flexibility and easy installation.
- Usage:
1. Selection: Choose the specification matching the nozzle/equipment thread (NPT/BSP) and hose diameter (1.5", 2");
2. Installation: Connect the thread end to the nozzle/equipment, insert the barb end into the hose, and tighten — **integrated structure, no disassembly required**;
3. Operation: The hose rotates 360° freely without dead angles, with no need for extra maintenance.

3. Product Advantages & Selection Logic
- Advantages:
① Copper-aluminum composite: Copper thread end ensures strong sealing; aluminum alloy barb end offers lightweight and fuel-corrosion resistance;
② Integrated 360° swivel: No-disassembly installation and no-dead-angle rotation eliminate large-diameter hose entanglement;
③ Large-size adaptation: Covers 1.5", 2" diameters, NPT/BSP threads adapt to mainstream dispensers.
