## Summary description

Set of two Creality pneumatic push-fit connectors sized 2.5 mm and 4 mm for secure tubing connections in 3D printer filament feeds, pneumatic lines or small air systems. Each connector supports quick insertion and release of flexible tubing without tools and is suitable for replacement or upgrade of feed and air fittings. Compatible where these inner diameters are required.

## Long description

Set of two Creality pneumatic push-fit connectors designed for secure and tool-free connections of flexible tubing in 3D printers, pneumatic lines and compact air systems. The set includes connectors for 2.5 mm and 4 mm inner-diameter tubing, allowing straightforward replacement or upgrade of filament feed fittings and small pneumatic joints. Each connector provides a sealed grip that enables quick insertion and release of tubing while maintaining a compact footprint suitable for tight assemblies.
Advantages
The push-fit connectors offer simple, fast installation without the need for clamps, adhesives or specialized tools. Their sealing mechanism reduces the risk of air leaks and ensures reliable filament feed or pneumatic performance. The compact design fits well into constrained printer frames and small pneumatic manifolds, and the two-size set covers common tubing diameters used in consumer 3D printers and hobby pneumatic systems.
Suitable for
 3D printer filament feed lines where 2.5 mm or 4 mm inner-diameter tubing is used
 Replacement or upgrade of pneumatic fittings on hotends, extruders and Bowden tubes
 Small pneumatic circuits, air tools and hobby projects requiring quick-connect tubing
Key specifications
 Connector types: push-fit pneumatic connectors for flexible tubing
 Compatible tube inner diameters: 2.5 mm and 4 mm
 Connection method: quick insertion with release collar for tool-free disengagement
 Sealing: built-in O-ring style seal for leak-resistant joints
 Material characteristics: durable plastic body compatible with low-pressure pneumatic and filament feed applications
 Application environment: indoor use with non-corrosive gases and standard 3D printing environments
How to use
Ensure tubing ends are cut square and free of debris before insertion. Push the tubing firmly into the connector until it seats against the internal stop; you should feel a positive engagement. To remove tubing, depress the release collar and pull the tubing out while maintaining pressure on the collar. Install connectors in-line or in fittings on printer frames and pneumatic manifolds as required, taking care not to over-bend the tubing near the connection point.
Usage recommendations
Inspect connections periodically for wear or deformation, especially in high-temperature areas near hotends. Use tubing with the correct inner diameter (2.5 mm or 4 mm) for a secure fit; mismatched tubing may leak or disengage. For high-pressure or specialty gas applications, consult system specifications and select fittings rated for the operating conditions.
