Description

Prevost Conex Micro Equal Straight Union

Ultra-Compact Connectivity for Precision Micro-Pneumatics

The Prevost Conex Micro Equal Straight Union is a miniaturized push-to-connect fitting designed to join two sections of small-diameter pneumatic tubing in a straight line. Engineered for applications where space is the primary constraint, the Micro series provides all the reliability of standard industrial fittings but with a significantly reduced footprint.

This union is the ideal solution for high-density automation, medical devices, and intricate laboratory instrumentation where traditional fittings are simply too large to fit.

Key Features

• Miniaturized “Micro” Design: Specifically optimized for small-bore tubing (typically 3mm, 4mm, or 6mm). Its ultra-slim profile allows for high-density tubing runs in confined spaces like robotic arms, small control boxes, and dental equipment.
• Instantaneous “Grip” Technology: Despite its small scale, it features Prevost’s signature stainless steel gripping rings. Simply push the tubing in for an immediate, airtight, and vibration-resistant seal—no tools or clamps required.
• Full-Flow Internal Path: The internal bore is precision-molded to match the tubing’s inner diameter. This ensures zero restriction and prevents pressure drops, which is critical for the low-volume air signals used in micro-pneumatics.
• Rapid Disconnection: The ergonomic manual release collars allow for instant removal of the tubing.¹ This makes maintenance and reconfiguration fast and easy, even in tightly packed assemblies.
• Corrosion-Resistant Composite: Manufactured from high-impact technical polymer, this union is lightweight yet durable, resisting common industrial chemicals, moisture, and oils.

The Solution for Modern “Nano” Automation

In modern manufacturing, machines are becoming smaller while performance demands stay high. The Prevost Conex Micro Equal Straight Union addresses this by allowing for “floating” connections that don’t add weight or bulk to the system. It is particularly effective for:

1. In-Line Splices: Repairing a damaged micro-line without replacing the entire run.
2. Extending Lines: Adding length to miniature sensor lines or pilot signals.
3. Weight-Sensitive Applications: Reducing the load on high-speed robotic “pick-and-place” heads.

Ideal Applications

• Electronic Assembly: Routing air to miniature grippers on SMT (Surface Mount Technology) machines.
• Medical & Lab Devices: Connecting gas and air lines inside compact diagnostic and analysis equipment.
• Pneumatic Pilot Circuits: Joining small-diameter signal lines in complex air-logic control panels.
• Micro-Robotics: Managing air distribution in small-scale robotic grippers and articulating joints.

Installation Tip

Because micro-tubing has thinner walls than standard tubing, it is essential to use a sharp, dedicated tube cutter (like the Prevost R22 CT) to avoid deforming the tube during the cut. Ensure the tube is pushed firmly until it “seats” past the internal O-ring to guarantee a 100% leak-free connection.
