Push-in fittings are so defined as they allow to connect the tube to the fitting in a “instantaneous” way without using tools.
The tightness of the tube takes place through an elastic clamp which holds the tube on the external diameter and releases it by pushing the suitable puller.
This type of fittings is used in order to speed up the assembly phases mainly in reduced space and timesaving during connection of different pneumatic components.

The role of Push-In Fittings in Pneumatic Systems
In industrial pneumatic systems, every connection point between a tube and a component is a potential critical element: a non-uniform seal generates pressure losses that propagate throughout the entire network, increasing compressed air consumption and compromising the repeatability of operating cycles.
Push-in fittings eliminate variables related to manual tightening, making the connection immediate, repeatable, and independent of the operator’s skill. The result is a measurable reduction in assembly times and, during maintenance operations, the possibility of replacing a tube in just a few seconds without tools.
Operating principle and sealing performance
The locking mechanism is based on an internal elastic collet that contracts radially around the outer diameter of the tube when inserted. The collet geometry is designed so that axial traction — generated by fluid pressure or external stresses — enhances the grip rather than loosening it.
