Stainless Steel Flanged Swivel Jet A1 Fuel Fitting
Our flanged high-pressure swivel joints are core connection components specifically engineered for ground-based fuel delivery systems. Widely used in airport refueling trucks, hydrant pits, and bulk fuel transfer lines, they ensure efficient, leak-proof, and flexible connections for the transfer of jet fuel, diesel, and gasoline, guaranteeing absolute safety and reliability in ground fueling operations.
- Product Introduction
This product is a precision fluid transfer component engineered specifically for Modern Aviation Ground Support Equipment (GSE). Serving as the critical (hub) between fixed piping/refuelers and flexible hoses, it resolves the stress concentration issues inherent in traditional rigid connections during dynamic operations.
Core Value: It delivers 360° unrestricted rotation while withstanding high-pressure fuel surges, completely eliminating hose kinking, torsional stress, and premature wear. This ensures leak-free operations, enhances personnel safety, and maximizes equipment lifespan in demanding airport environments.
Key Application Scenarios
Airport Hydrant Dispensers
Challenge: High pressure from underground networks and hose dragging as vehicles move.
Solution: Installed at the dispenser outlet, acting as a "universal joint" that allows refuelers to park and maneuver at any angle without manual hose adjustment, significantly improving turnaround time.
Tanker Refuelers
Challenge: Torsion generated during hose reel retraction transfers stress to the pump outlet, causing pipeline fatigue.
Solution: Mounted between the pump discharge and reel inlet to absorb reactive torque, protecting the onboard pump assembly and piping.
Top Loading Arms
Challenge: Variable truck positions require large-range articulation of the loading arm.
Solution: Serves as a pivot node for the loading arm, providing multi-degree-of-freedom movement to precisely align with tank hatches of varying heights.
Emergency & Field Refueling
Advantage: Modular design allows for rapid replacement without specialized tools, ideal for quick deployment in remote or military field operations.
Typical Application Scenarios
Connection Type: Flanged (Standard sizes available, custom options supported)
Body Material: High-Strength Carbon Steel or Stainless Steel (optional)
Seal Material: Specialty Fluoroelastomer/Polyurethane (Standard), other materials available based on fluid compatibility
Working Pressure: Up to [e.g., 1.0 MPa or 150 psi] [To be filled with actual product parameters]
Temperature Range: -30°C to +100°C [To be confirmed based on seal material]
Rotation: 360° continuous rotation in a single plane
Maintenance & Lifecycle Management
Preventive Maintenance Recommendations
Daily Inspection: Visually check for smooth rotation, abnormal noise, or leaks during every shift change.
Periodic Lubrication: For non-maintenance-free models, inject specified aviation-grade grease via grease nipples every 6-12 months depending on usage frequency.
Seal Replacement: Recommend replacing the full seal kit every 3-5 years or after a specific operational cycle to prevent rubber aging failures.
Troubleshooting Guide
Stiff Rotation: Usually caused by bearing failure, foreign object intrusion, or lack of lubrication.
External Leakage: Indicates worn primary seals or aged O-rings; immediate shutdown and replacement required.
Internal Cross-Leakage: For double-seal models, observe the weep hole. Oil presence here is an early warning of primary seal failure.
