Prevost Conex Micro Bulkhead Fitting

Description

Prevost Conex Micro Bulkhead Fitting

Ultra-Compact Transition for Panel-Mount Applications

The Prevost Conex Micro Bulkhead Fitting is a high-performance, miniaturized solution designed to pass pneumatic lines through machine panels, cabinet walls, or bulkheads. Part of the specialized Micro series, this fitting is engineered for high-density environments where space is at a premium and standard bulkhead connectors are too large to be practical.

By providing a secure, fixed mounting point, it protects tubing from friction and mechanical stress at the transition point, ensuring an airtight seal and a professional, organized finish for your equipment.

Key Features

• Miniaturized Footprint: Specifically designed for small-bore tubing (typically 3mm, 4mm, or 6mm). Its low-profile design allows for multiple connections to be mounted in close proximity on a single control panel.
• Instantaneous “Grip” Technology: Features Prevost’s signature stainless steel gripping rings on both sides. Simply push the technical tubing (PU, PA, or PE) into the fitting for a tool-free, vibration-proof connection.
• Secure Threaded Mounting: Equipped with a rugged threaded body and locking nut, allowing the fitting to be tightened securely against a panel. This prevents the pneumatic line from moving or “sawing” against the panel edge, which can lead to tubing failure.
• Nickel-Plated Brass Construction: Manufactured with a high-grade nickel-plated brass body for superior mechanical strength and resistance to corrosion, ensuring the bulkhead can withstand the tension of connected tubing.
• Full-Bore Flow Efficiency: The internal geometry is optimized for micro-pneumatics, maintaining consistent pressure and airflow with zero restriction—a critical requirement for sensitive sensors and miniature actuators.

The Professional Finish for Compact Enclosures

In precision automation, routing air lines through an enclosure without a bulkhead is a risk; vibration can cause the enclosure edge to cut through the tubing over time. The Prevost Conex Micro Bulkhead Fitting eliminates this risk by creating a rigid “anchor point.” It provides a clean interface for the user, allowing external lines to be disconnected and reconnected without disturbing the internal plumbing of the machine.

Ideal Applications

• Control Cabinets: Creating high-density pneumatic interfaces on the exterior of small electrical or control boxes.
• Medical Diagnostic Equipment: Passing sensitive gas or air lines through the chassis of desktop medical instruments.
• Lab-on-a-Chip & Analytics: Managing intricate micro-fluidic or pneumatic signals in laboratory hardware.
• Robotics & Cobots: Serving as a transition point for air lines passing from a robot’s internal arm to the end-of-arm tooling (EOAT).

Installation Tip

When drilling your panel, ensure the hole diameter matches the outer thread of the bulkhead body. For a perfectly square and leak-free connection, always use a dedicated tube cutter to prepare your micro-tubing. Tighten the lock-nut firmly against the panel to ensure the fitting remains stationary under vibration.
