Prevost Conex Plug

The Simple Solution for Secure System Termination

The Prevost Conex Plug is a vital accessory for any pneumatic circuit, designed to quickly and securely seal off unused ports in push-to-connect fittings. Whether you are blanking off a spare outlet on a manifold or temporarily sealing a line during maintenance, the Conex Plug provides an airtight, pressure-rated termination that is just as easy to install as your air tubing.

Built with the same high standards as the rest of the Conex range, these plugs ensure that your system remains pressurized and leak-free without the need for permanent caps or messy adhesives.

Key Features

• Instant “Push-In” Installation: Designed to mimic the outer diameter (OD) of standard pneumatic tubing. Simply push the plug into any Conex or push-to-connect fitting to create an immediate, high-pressure seal.
• Tool-Free Removal: To open the port back up, simply depress the release collar on the fitting and pull the plug out. This makes it the ideal choice for modular systems that require frequent reconfiguration.
• High-Integrity Seal: Precision-molded to ensure a perfect fit against the internal O-ring of the fitting. This prevents the “slow leaks” often associated with improvised or lower-quality port blockers.
• Ergonomic Head Design: Features a knurled or flared head that provides a solid grip for manual insertion and removal, even in oily or damp workshop environments.
• Durable Technical Polymer: Constructed from high-impact, corrosion-resistant technical polymer that is compatible with compressed air, vacuum, and neutral gases.

Why Use a Dedicated Conex Plug?

In a professional pneumatic setup, improvising with “stub” pieces of tubing and folded ends is a common source of energy loss and safety hazards. The Prevost Conex Plug is a purpose-built component that:

1. Eliminates Leaks: Provides a factory-level seal that won’t degrade under vibration.
2. Improves Safety: Prevents the accidental discharge of air if a valve is bumped.
3. Looks Professional: Maintains the clean, organized aesthetic of a high-quality Prevost installation.

Ideal Applications

• Manifold Management: Sealing off unused ports on multi-station solenoid valve blocks.
• System Maintenance: Temporarily “capping” an air line while downstream tools are being repaired or replaced.
• Modular Workstations: Closing off air drops that are only used for seasonal production runs.
• Pressure Testing: Isolating specific sections of a pneumatic circuit during leak detection or commissioning.

Selection Tip

Conex Plugs are sized according to the Internal Diameter of the Fitting (which matches the Outer Diameter of the Tubing). For example, if you are using 8mm tubing, you will need an 8mm Conex Plug.
