Prevost Conex Female Banjo

Description

Prevost Conex Female Banjo

Low-Profile 90° Connectivity with Integrated Threaded Port

The Prevost Conex Female Banjo is a specialized, low-profile pneumatic fitting designed for tight spaces where a standard elbow or tee would be too bulky. It combines a push-to-connect tubing port with a female threaded rotating body, allowing you to mount threaded accessories—such as gauges, sensors, or specialty valves—at a right angle to your tubing run.

The “Banjo” design is highly valued in modular machine building because it provides a compact, swivel-ready junction that can be secured with a hollow bolt (sold separately) or used as a modular stacking component in complex pneumatic logic.

Key Features

• Ultra-Compact 90° Interface: The flattened “banjo” profile allows the fitting to sit much closer to the mounting surface than a traditional elbow. This is critical for plumbing air lines in shallow control cabinets or on compact robotic arms.
• 360° Rotational Freedom: The body rotates fully around the central axis even after being tightened. This ensures that the push-in tubing port can be aimed in the exact direction needed for clean, stress-free hose routing.
• Integrated Female Thread: Features a precision-machined internal thread (typically NPT or BSPP) that accepts male-threaded components. This allows for the direct mounting of pressure switches or small-bore air tools without the need for additional adapters.
• Instantaneous “Grip” Technology: The tubing port is equipped with Prevost’s signature stainless steel gripping ring. Simply push the technical tubing (PU, PA, or PE) in for a secure, vibration-proof, and airtight seal—no tools or clamps required.
• Rugged Hybrid Construction: Combines the mechanical strength of nickel-plated brass with a high-impact technical polymer body, ensuring resistance to corrosion, moisture, and industrial oils.

The Versatile Link for Modular Pneumatics

The Prevost Conex Female Banjo acts as a “hub” for pneumatic accessories. Its unique geometry makes it the preferred choice for:

1. Direct Sensor Integration: Mounting a pressure transducer or gauge directly onto a cylinder port or manifold while maintaining a tubing connection.
2. Manifold Stacking: Creating custom distribution blocks by stacking multiple banjos together using a single long hollow bolt.
3. Restricted Clearances: Routing air lines through narrow gaps in machine frames where a standard fitting would hit the enclosure.

Ideal Applications

• Pneumatic Control Panels: Mounting pressure gauges or signal lights at 90 degrees to the internal tubing.
• Automated Machine Tools: Connecting air-cooled spindle lines where space around the motor is limited.
• Process Valves: Adding a manual test port or pilot line to a larger process valve assembly.
• Custom Manifolds: Building compact, multi-directional air distribution hubs for robotic end-effectors.

Installation Tip

When installing the banjo with a hollow bolt, ensure that the sealing washers (usually copper or nylon) are placed on both sides of the banjo body to prevent air bypass. For the tubing side, always use a dedicated tube cutter to ensure a square end, which guarantees the stainless steel gripping ring engages the tube perfectly.
