About the Airtac PP Pipe Plug PP12
The PP12 is an AirTAC PP plug from the resin one-touch range: a plain Dia 12 plug with no thread of its own, made to be pushed into the open socket of a Dia 12 one-touch fitting and seal that port off. It belongs to the resin/brass spec profile, so it carries the full 0-1.0 MPa (0-10 kgf/cm2) working pressure, a -750 mmHg (10 Torr) vacuum rating, a 1.5 MPa proof pressure and a -20 to +70 C temperature band. The plug body is POM with an NBR sealing ring, matching the grey standard finish of the rest of the resin range; add a D to the code and the body comes in black.
Fitting it takes one motion: push the PP12 straight into the vacant socket exactly as you would a length of 12mm tube, and the internal seal rings up against the seat to close the port. To remove it, press the release button on the host fitting and draw the plug out - no tools, no thread tape, nothing to torque. It is the cleanest way to blank a spare outlet during commissioning or to close a circuit you may later re-open.

Fitting & Sealing Notes
- check Cut the tube square and clean before pushing it home, or the seal will leak.
- check Push until it stops, then pull back to check the chuck has gripped.
- check To release, press the collet ring fully in and pull the tube out.
- check Threaded parts arrive with sealant on the thread; M5 sizes use a sealing gasket.
- check Match the tube OD exactly - a 6 mm fitting will not hold 1/4" tube.
Where the Airtac PP Pipe Plug PP12 Is Used
Blanking spare outlets on a valve manifold
A 5-station solenoid manifold on a bottling line often leaves one or two ports unused for future stations. A PP12 pushed into each vacant Dia 12 outlet keeps dust and moisture out of the manifold galleries without removing the whole assembly.
Staged commissioning of a pneumatic circuit
When a packaging machine is built with circuits that are only activated in phase two, the temporary Dia 12 branch points can be closed with PP12 plugs during leak testing, then swapped for live fittings at handover.
Isolating a decommissioned machine drop
A retired rotary table feed on a machining cell can be left physically connected but sealed: plug the Dia 12 socket at the drop and the circuit stays isolatable later, with no open push-in port venting to the shop floor.
Is the Airtac PP Pipe Plug PP12 the Right Part?
PP12 sits at the top of the plug ladder: the next size down is PP10 for Dia 10 sockets, and there is nothing above it - the range ends at Dia 12 with no 16mm tube size in this catalogue. Whichever plug you pick, the socket must match exactly: a PP12 will not seal in a Dia 10 or Dia 8 outlet, and forcing a size mismatch only chews the O-ring. Also note the plug caps a fitting socket, not a loose tube end - if you need to terminate a 12mm line, branch it through a union tee such as the PE12 and plug the spare leg instead.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
Airtac PP Pipe Plug PP12 FAQ
The PP12 is a Dia 12 plug with no thread, on the resin one-touch spec: working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature range of -20 to +70 C. The body is grey POM as standard; the D suffix orders the black version.
No. The plug is sized to seat inside the socket of a Dia 12 one-touch fitting, not to grip tubing - it has no chuck of its own. To terminate a free 12mm line, land the tube on a fitting with a spare leg (a PE12 union tee or a PD-style branch) and seal the unused outlet with the PP12. Remember the host socket must be Dia 12 exactly; a Dia 10 socket will not take it.
