Jinqi Pneumatic Plastic Straight Through Quick Insertion Connector for 4-16mm Tubing in Automation Systems

In pneumatic automation setups, every second saved on connection time improves overall efficiency. The Jinqi pneumatic plastic connector straight through butt design allows you to quickly insert trachea tubing of various outer diameters from 4mm up to 16mm. Made from low shrinkage POM and PBT with imported O-rings, this connector provides a reliable seal without the need for additional tools. Its temperature resistance range of 0-60°C and pressure capacity of 0-1 MPa make it a practical choice for industrial air lines and control systems.

Features and Construction

The connector builds on straightforward engineering principles: a one-piece body with a collar release mechanism and an internal O-ring. Each component is chosen for its performance in continuous use environments.

Material and Build

Low shrinkage POM and PBT form the main body. These materials keep dimensional tolerance tight, so the connector holds the tube securely even after multiple insertion cycles. Imported O‑rings sit inside the connector to create an airtight seal, reducing leakage risk.

Size and Practical Fit

Seven models correspond to standard tube diameters: PU-04 (4mm), PU-06 (6mm), PU-08 (8mm), PU-10 (10mm), PU-12 (12mm), PU-14 (14mm), and PU-16 (16mm). You can use one connector type for a specific tube size, or mix models across a system to handle different line diameters.

Uses and Placement

These connectors are designed for straight through butt connections in pneumatic circuits. The quick‑insert mechanism is suited for high‑density panels where fast assembly matters.

Event or Professional Use

Automation engineers and maintenance teams working on production lines, packaging machinery, or robotic cells can rely on this connector for rapid tubing changes. The 100‑piece pack covers large installations without frequent re‑ordering.

Everyday Home Use

Workshops and hobbyists using compressed air for tools or small automation projects can replace worn connectors in seconds. The standard tube sizes match many hobby‑grade pneumatic components.

Benefits and Buying Value

The connector’s value lies in its simplicity, repeatable performance, and quantity packaging.

Reuse and Low Maintenance

Push‑to‑connect fittings allow tube removal and re‑insertion without damaging the connector or tube. The POM/PBT body resists creep and cracking at operating temperatures up to 60°C, so the connector stays functional through many cycles.

Why Choose This Product

If you need a reliable straight‑through connector for pneumatic tubing of 4mm to 16mm, made from materials known for low shrinkage and thermal stability, this Jinqi part is a direct fit. The black colour suits standard industrial aesthetics, and the 100‑unit pack supports bulk installations.
