Plug Push To Connect Fitting

Close Unused Push-In Pneumatic Ports Quickly and Cleanly

PP Series push-to-connect fittings are designed to seal an unused compatible push-to-connect tube port in compressed air and pneumatic automation systems. This category sits within PneumaticHub's Push To Connect Inch Tube Fittings range and is intended for inch 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 machines and pneumatic circuits built around inch-size tubing.

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 Plug Fitting?

A push-in plug is useful during machine commissioning, maintenance or future expansion when a pneumatic port needs to remain closed.

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 the push-to-connect port or tube size being plugged.

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
