One-Touch Tube Connections for Pneumatic Valves, Cylinders and Manifolds
Push-to-connect tube fittings are used to join pneumatic tubing quickly without compression nuts or hose clamps. They connect polyurethane, nylon and other compatible pneumatic tube to valves, cylinders, manifolds and other compressed air equipment.
The one-touch design allows tube to be inserted directly into the fitting and released through the collet for maintenance or circuit changes. PneumaticHub supplies multiple configurations for compact machine plumbing and industrial automation.

Frequently Asked Questions
What is a push-to-connect tube fitting?
It is a pneumatic fitting that grips and seals tubing when the tube is pushed into the fitting body.
What tubing can I use?
Polyurethane and nylon are common, but the tube outside diameter and material must meet the fitting specification.
Can the tubing be disconnected and reconnected?
Yes. The collet releases the tube so the connection can be serviced or changed.
What pressure can these fittings handle?
Applicable models in this range are specified up to 150 psi / 10 bar working pressure, but always confirm the individual product rating.
Can they be used for vacuum?
Applicable models can be used for vacuum within their published specification.
How should pneumatic tube be cut?
Cut tubing squarely with a proper tube cutter and avoid crushed, angled or scratched ends.
What causes push fitting leaks?
Common causes include incorrect tube size, damaged tube, incomplete insertion, debris, seal wear or an improperly sealed threaded connection.
