Jinqi PU Straight Through Pneumatic Connector for 4mm to 16mm Tubing in Automation Equipment

The Jinqi PU straight through connector serves as a practical component for pneumatic systems in automated machinery and industrial equipment. Designed as a quick insertion connector, it enables straightforward joining of trachea without requiring specialised installation tools. This connector accommodates tubing with outer diameters ranging from 4mm to 16mm, with specific model designations (PU-04 through PU-16) corresponding to each size. It operates effectively within temperature parameters of 0-60°C while handling pressures up to 1 MPa, making it suitable for various automated applications where reliable air connections are necessary.

Features and Construction

The connector's design focuses on functional reliability and straightforward installation. Its quick insertion mechanism allows users to connect pneumatic tubing directly without additional fasteners or tools, streamlining maintenance and assembly processes in automated environments. The construction addresses common requirements in industrial settings where repeated connections and disconnections may occur during equipment servicing or reconfiguration.

Material and Build

This pneumatic connector utilises low shrinkage POM (polyoxymethylene) and PBT (polybutylene terephthalate) in its construction. These materials provide dimensional stability under varying temperature conditions while maintaining mechanical integrity. The inclusion of imported O-rings ensures consistent sealing performance between connector components, preventing air leaks in pneumatic systems. The material selection supports the connector's specified operating range of 0-60°C without compromising its structural form or sealing capability.

Size and Practical Fit

The connector series includes seven distinct size designations from PU-04 to PU-16, each corresponding to a specific trachea outer diameter measurement. The PU-04 model accommodates 4mm tubing, PU-06 fits 6mm tubing, PU-08 accepts 8mm tubing, PU-10 matches 10mm tubing, PU-12 suits 12mm tubing, PU-14 fits 14mm tubing, and PU-16 accommodates 16mm tubing. This graduated sizing system enables precise matching between connector and tubing dimensions, ensuring secure connections across various pneumatic applications in automation equipment.

Uses and Placement

This connector series finds application in automated systems where pneumatic components require reliable interconnection. The quick insertion design facilitates efficient assembly and maintenance procedures, particularly in environments where tubing connections need regular attention or modification. The temperature and pressure specifications make it suitable for typical industrial pneumatic applications rather than extreme operating conditions.

Event or Professional Use

In professional automation equipment, these connectors serve as junction points between pneumatic actuators, valves, and control systems. Their quick insertion capability allows technicians to make connections efficiently during machine assembly, repair, or reconfiguration. The availability in a whole package of 100 pieces supports bulk usage scenarios commonly encountered in manufacturing facilities, maintenance workshops, and equipment assembly operations where multiple identical connections are required across various machines or production lines.

Everyday Home Use

While primarily designed for automation equipment, these connectors may find application in home workshop pneumatic systems, hobbyist automation projects, or small-scale compressed air setups. The straightforward installation without specialised tools makes them accessible for users with basic technical skills. The temperature range of 0-60°C accommodates typical indoor environments, while the pressure resistance up to 1 MPa covers common low-to-medium pressure pneumatic applications outside industrial settings.

Benefits and Buying Value

The connector offers practical advantages through its material composition and design approach. The low shrinkage materials maintain dimensional accuracy across the specified temperature range, while the imported O-rings contribute to consistent sealing performance. The quick insertion mechanism reduces installation time compared to threaded or clamped connection methods, potentially streamlining maintenance procedures in automated systems.

Reuse and Low Maintenance

The connector design allows for repeated connection and disconnection cycles without significant degradation, supporting maintenance and reconfiguration activities in automated equipment. The material properties help maintain structural integrity through multiple use cycles under the specified operating conditions. The O-ring sealing approach provides reliable performance while allowing component replacement if necessary, rather than requiring complete connector replacement for minor seal issues.

Why Choose This Product

This connector series addresses specific requirements in pneumatic system connectivity through its graduated sizing system, material selection, and operating specifications. The availability in a whole package of 100 pieces provides economical sourcing for applications requiring multiple identical connectors. The combination of low shrinkage materials, imported O-rings, and quick insertion design creates a functional solution for joining pneumatic tubing in automated environments where reliability and straightforward installation are priorities.
