Reducing Nipple Push To Connect Fitting

Compact Plug-In Transitions Between Different Pneumatic Port Sizes

PIG Series push-to-connect fittings are designed to connect compatible push-to-connect interfaces while reducing between different connection sizes in compressed air and pneumatic automation systems. This category sits within PneumaticHub's Push To Connect mm Tube Fittings range and is intended for millimetre outside-diameter pneumatic tubing.

The one-touch fitting design allows compatible polyurethane, nylon and other suitable pneumatic tubing to be installed quickly and removed for maintenance when the system is safely depressurized. The fitting geometry is especially useful for metric pneumatic systems and imported machinery.

Operating Specifications

• Fluid medium: Air
• Working pressure: 0–150 psi(g) / 10 bar(g)
• Proof pressure: 450 psi(g) / 30 bar(g)
• Vacuum duty: 29.5 inHg / 14 mbar(a)
• Working temperature: 32–140°F / 0–60°C

Why Use This Reducing Nipple Fitting?

A reducing nipple can provide a short, direct size transition in compact pneumatic assemblies.

Push-to-connect tube installation helps reduce assembly time compared with many conventional tube-connection methods.

Key Benefits

• Tubing can be disconnected and reconnected for maintenance or machine changes when the circuit is safely depressurized.
• Compact bodies help keep pneumatic plumbing organized around valves, cylinders, manifolds and control panels.
• Correct selection should consider larger and smaller compatible push-in sizes and installation spacing.

Common Applications

• Industrial automation machinery
• Pneumatic cylinders and actuators
• Directional control valves and manifolds
• Packaging and assembly equipment
• Robotics and material handling
• OEM pneumatic equipment
• General factory compressed air systems
