Jinqi PU Series Straight-Through Pneumatic Quick Connector for 4-16mm Tubing in Automation

This Jinqi pneumatic connector provides a straightforward, reliable linking point for PU air lines in automated machinery and systems. Supplied in a bulk pack of 100 units, it offers a practical solution for installers and maintenance technicians who require multiple connection points. The connector's core function is to join sections of PU tubing quickly and securely, supporting a working pressure of up to 1 MPa and functioning within an ambient temperature range of 0 to 60 degrees Celsius. Its design is focused on the needs of automation equipment, where consistent air flow and ease of assembly are key considerations.

Features and Construction

The Jinqi connector is built around a practical quick-insertion mechanism, allowing tubing to be connected without the need for tools or complex procedures. This section details the materials used in its construction and the specific sizing that determines its application.

Material and Build

The connector body is manufactured from low-shrinkage grades of POM (Polyoxymethylene) and PBT (Polybutylene terephthalate) plastics. This material choice is geared towards maintaining dimensional accuracy and mechanical strength under the stated operating conditions. The sealing function is handled by imported O-rings integrated into the design, which are responsible for creating an airtight seal once the PU tubing is inserted. The product is confirmed to be made from a blue PU material, referring to its colour and plastic type.

Size and Practical Fit

This connector series is not a one-size-fits-all product; it is produced in specific models to match standard PU tubing outer diameters. The model number directly corresponds to the tube size it accepts: a PU-04 connector is for 4mm outer diameter tubing, PU-06 for 6mm, PU-08 for 8mm, PU-10 for 10mm, PU-12 for 12mm, PU-14 for 14mm, and PU-16 for 16mm tubing. This range from 4mm to 16mm covers common sizes used in many pneumatic control applications, ensuring you can select the correct fitting for your system's tubing.

Uses and Placement

With its specified parameters and quick-connect design, this connector has clear applications in industrial and mechanical settings. Its use is defined by the environment it is designed for and the scenarios where its bulk packaging offers an advantage.

Event or Professional Use

The primary and stated application for this connector is within automation equipment. This includes assembly lines, packaging machinery, material handling systems, and other automated processes where pneumatic controls are used. The pack of 100 connectors is particularly relevant for professional installers, factory maintenance teams, or system integrators who are building or servicing multiple machines or extensive pneumatic networks, reducing the need for frequent reordering.

Everyday Home Use

While designed for automation equipment, these connectors could also be utilised in advanced hobbyist or workshop settings where small-scale pneumatic systems are built, such as in custom robotics, model-making, or small tooling applications. Users must ensure their intended use falls within the product's performance limits of 0-60°C and 1 MPa pressure.

Benefits and Buying Value

The value of this product lies in its specificity and practicality. It addresses common needs in pneumatic system setup with a no-frills approach focused on reliable performance and supply convenience.

Reuse and Low Maintenance

The connector is designed for a push-to-connect action, which generally allows for tubing to be disconnected and reconnected as needed during system reconfiguration or maintenance. The use of durable POM and PBT plastics suggests a construction intended for repeated use within its rated parameters, though no specific lifespan data is provided. The imported O-rings are central to maintaining a seal over time.

Why Choose This Product

Choosing this Jinqi connector is a decision based on matching a specific need: connecting PU tubing in an automation context. Its advantages are clear: the availability of seven precise sizes (4mm to 16mm), the convenience of a 100-piece bulk pack for projects requiring many connections, and construction from engineered plastics suited to the task. It provides a component that fits defined technical requirements without superfluous features, making it a logical choice for its intended purpose.
