Push to Connect Fittings

Fast, Reusable Pneumatic Connections for Inch and Metric Tubing

Push-to-connect fittings provide a fast way to connect pneumatic tubing to valves, cylinders, manifolds and other compressed air equipment. PneumaticHub supplies push-in fittings for both inch and metric tube sizes with multiple thread options for industrial automation and machine building.

The fitting design grips the tube mechanically while an internal seal provides the air connection. Tubing can be installed by pushing it fully into the fitting and released using the collet, allowing circuits to be assembled and serviced quickly without compression nuts or special tools.

Frequently Asked Questions

How does a push-to-connect fitting work?

The tube is pushed through a release collet into an internal seal while a gripping mechanism holds the tube in place.

How do I release tubing from a push-in fitting?

Depress the release collet evenly toward the fitting body while pulling the tube straight out.

Can push-to-connect fittings be reused?

Yes. Quality fittings are designed for repeated tube connection and disconnection when the tubing and fitting remain in good condition.

What tubing works with push-to-connect fittings?

Common compatible tubing includes polyurethane and nylon, but tube material and dimensions must match the fitting specification.

What is Universal Thread?

In applicable Pneuforce fittings, Universal Thread is designed to connect with several common female pipe thread standards, reducing the number of thread variants that need to be stocked.

Can push-in fittings be used for vacuum?

Many pneumatic push-in fittings can be used for vacuum within their specified rating.

How do I prevent leaks?

Use correctly sized, undamaged tubing cut squarely and push it fully into the fitting. Threaded ends also need the correct sealing method where applicable.
