Why Choose Metric Tube Fittings?

Metric pneumatic tubing is common on European and Asian machinery and on many modern automation platforms. Using the correct metric fitting avoids improper tube grip and sealing that can occur when inch and metric sizes are mixed.
Always match the marked tube outside diameter and verify the thread standard on any threaded connection.

Imported and globally designed machinery
Packaging equipment
Robotics
Pneumatic cylinders
Valve manifolds
OEM automation

Frequently Asked Questions

What is a metric push-to-connect fitting?

It is a pneumatic fitting sized for tubing with outside diameters specified in millimeters.

Can I use inch tubing in a metric fitting?

No, unless the dimensions are explicitly specified as compatible. Similar-looking inch and metric tube sizes can differ enough to cause poor grip or leakage.

What tubing materials are commonly used?

Polyurethane and nylon are common choices when they meet the fitting dimensional and pressure requirements.

How do I install metric pneumatic tubing?

Cut the tube squarely, push it fully into the fitting until it bottoms, then gently pull back to confirm it is retained.

How do I remove the tube?

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

What pressure can metric push fittings handle?

Applicable models are rated up to 150 psi / 10 bar working pressure, but confirm the exact product specification.

Where are metric push fittings commonly used?

They are common on automation equipment, robotics, packaging machinery, pneumatic cylinders and valve manifolds.
