Mini Type Pneumatic Push In Fittings

What are mini quick connect fittings?

Mini Type Pneumatic Push In Fittings are a category of mini quick connect fittings specifically designed for small-diameter pneumatic systems (typically for tubing with outer diameters of Φ4, Φ6, Φ8, Φ10, and Φ12mm). The core principle of quick connect fittings is to enable tool-free connection by simply "pushing in" the tubing, utilizing an internal grip ring and O-ring to achieve quick installation, secure locking, and reliable sealing.

Core Features

One-Touch Installation: No tools are required—simply push the tubing straight into the fitting until it seats fully to complete the connection.

One-Touch Disassembly: Press the transparent/colored release ring (collet) on the fitting to easily pull out the tubing.

Compact Design: Small in size and space-saving, especially suitable for modern highly integrated pneumatic control cabinets, valve manifolds, and precision equipment.

High Reliability: The internal stainless steel grip ring firmly holds the outer wall of the tubing, preventing it from loosening due to pressure or vibration; the O-ring ensures airtightness.

Multiple Materials: The body is commonly made of nickel-plated brass, stainless steel, or engineering plastics.

Excellent Flow Performance: The internal flow path is optimized to minimize pressure loss.
