Product Overview
Hydraulic Banjo is a compact fluid transfer fitting used to connect hydraulic hose assemblies or tubing to ports where installation space is restricted and conventional straight or elbow fittings are difficult to install.
Compact Installation Benefits
Space-Efficient Connection
The hollow bolt and ring-body design allows fluid transfer through the side of the fitting, reducing the installation envelope compared with conventional threaded connections.
Multi-Angle Hose Positioning
The banjo body can be positioned before final tightening, making it easier to route hoses around pumps, motors, cylinders, and valve blocks in confined spaces.
Reliable Fluid Passage
Cross-drilled flow channels provide continuous hydraulic flow while maintaining secure mechanical attachment through the banjo bolt assembly.
Suitable for Medium- and High-Pressure Systems
Commonly used in hydraulic circuits operating up to 250–350 bar, depending on size, material, and application requirements.
Precision Component Manufacturing
CNC Machined Flow Passages
Internal bores and cross-drilled channels are machined to maintain consistent flow characteristics across production batches.
Controlled Banjo Eye Machining
The sealing faces on both sides of the banjo eye are machined to ensure proper contact with sealing washers.
Bolt Thread Verification
Banjo bolts are inspected using calibrated thread gauges to verify dimensional compliance with specified thread standards.
Surface Protection Inspection
Plated components undergo coating appearance and coverage checks before assembly and shipment.
Assembly Traceability
Production batches are traceable through machining, plating, and inspection records.

Common Applications
Hydraulic Pumps and Motors
Used where ports are positioned close to housings and require low-profile hose routing.
Mobile Hydraulic Equipment
Commonly found in compact excavators, loaders, lifting equipment, and agricultural machinery.
Hydraulic Cylinders
Provides fluid connections in locations where standard fittings would interfere with machine movement.
Industrial Machinery
Suitable for hydraulic systems with restricted installation space around manifolds and actuators.
FAQ
Q: Why choose a banjo fitting instead of an elbow fitting?
A: A banjo fitting typically requires less installation space because the hose connection rotates around the banjo bolt axis rather than extending outward like a conventional elbow fitting.
Q: How is sealing achieved in a banjo connection?
A: Sealing is normally provided by washers positioned on both sides of the banjo eye and compressed when the banjo bolt is tightened.
Q: Can the fitting orientation be adjusted during installation?
A: Yes. The banjo body can usually be positioned to the required angle before the bolt is fully tightened.
Q: What are the most common causes of leakage?
A: Damaged sealing washers, incorrect torque, scratched sealing surfaces, or reused sealing washers are common causes.
Q: What information is required for quotation?
A: Thread size, banjo size, material requirement, sealing washer type, operating pressure, and application details help ensure correct product selection.
