PU Series Pneumatic Quick Connector for Straight Through Tubing Connections in Multiple Sizes

This pneumatic plastic connector provides a practical solution for creating secure connections between tubing ends in automation and pneumatic systems. Designed specifically for PU tubing series with blue colour identification, it offers a straightforward installation process through its quick insertion mechanism that requires no special tools. The connector's straight through butt configuration creates a direct passage between connected tubing, minimising flow restrictions and maintaining consistent pressure transmission throughout pneumatic circuits. With temperature resistance from 0-60°C and pressure handling up to 1 MPa, it suits various industrial automation applications where reliable tubing connections are essential for equipment operation.

Features and Construction

This connector combines practical design elements with materials selected for dimensional stability under varying operating conditions. The quick insertion mechanism streamlines installation processes, while material choices ensure reliable performance across the specified temperature and pressure ranges.

Material and Build

The connector housing utilises low shrinkage POM (Polyoxymethylene), a material known for maintaining dimensional accuracy and providing chemical resistance in industrial environments. Additional components are manufactured from PBT (Polybutylene terephthalate), offering thermal stability across the specified 0-60°C operating range. Imported O-rings create the sealing interface between the connector and tubing, designed to maintain integrity at pressures up to 1 MPa. This material combination ensures the connector performs reliably in automation equipment applications where consistent operation is required.

Size and Practical Fit

Available in seven distinct model sizes, each connector corresponds to specific tubing outer diameters for precise matching. The PU-04 model accepts 4mm outer diameter tubing, while the PU-06 accommodates 6mm tubing, PU-08 fits 8mm tubing, PU-10 suits 10mm tubing, PU-12 matches 12mm tubing, PU-14 accepts 14mm tubing, and PU-16 is designed for 16mm tubing. This sizing system ensures users can select exactly the connector needed for their specific pneumatic tubing, with the blue colour coding providing visual confirmation of PU tubing series compatibility across all available sizes.

Uses and Placement

Designed primarily for automation equipment applications, this connector serves various functions in pneumatic systems where tubing connections must be secure yet accessible for maintenance or reconfiguration. Its operating parameters make it suitable for environments with controlled temperature conditions and moderate pressure requirements.

Event or Professional Use

In professional automation settings, these connectors enable efficient assembly of pneumatic circuits where multiple tubing connections are required. The quick insertion design reduces installation time compared to threaded or clamped alternatives, while the colour-coded identification helps technicians quickly identify PU series tubing compatibility during system assembly or troubleshooting. The temperature and pressure specifications suit controlled industrial environments rather than extreme condition applications.

Everyday Home Use

While designed for automation equipment, these connectors may find application in home workshop pneumatic projects where PU tubing connections are needed. The straightforward insertion mechanism makes them accessible for DIY enthusiasts working on small-scale pneumatic systems, provided the temperature and pressure requirements remain within the specified 0-60°C and 0-1 MPa limits. Their simple design allows for connections that can be made and unmade as projects evolve or require modification.

Benefits and Buying Value

This connector offers practical advantages through its simplified installation process and material choices that support reliable operation within defined parameters. The availability of multiple sizes ensures users can match their specific tubing requirements without compromise.

Reuse and Low Maintenance

The quick insertion design allows connectors to be disconnected and reused when system reconfiguration is necessary, provided tubing ends remain undamaged. Material choices contribute to low maintenance requirements, with POM and PBT resisting degradation under normal operating conditions within the specified temperature range. The O-ring sealing system maintains performance through multiple connection cycles when used within pressure limits.

Why Choose This Product

This connector provides a specialised solution for PU tubing connections with its colour-coded identification and range of available sizes. The straight through butt configuration maintains consistent inner diameter for minimal flow restriction, while the quick insertion mechanism reduces assembly time compared to more complex connection methods. For applications requiring multiple connectors of the same type, the product's standardised design ensures consistent performance across installations.
