About the Airtac PP Pipe Plug PP12D
The AirTAC PP12D is a resin one-touch plug, the blanking member of the PP series. It pushes into a Dia 12 mm one-touch socket and closes that port off while the rest of the circuit stays live. Inside, the same chuck and release-ring mechanism used on the connector range grips the plug body, so it seats with a firm push and frees again when you press the release ring. The D suffix gives the plug a black finish rather than the standard grey.
This is the resin-brass spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The plug uses a POM release button and chuck, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring, so it seals against the same soft nylon or polyurethane tubing as every other P-prefix fitting in the catalogue.

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 PP12D Is Used
Spare ports on a packaging manifold
Multi-outlet manifolds on carton-sealing and blister machines are often drilled with more branches than the build uses. A PP12D closes the unused 12 mm one-touch outlets cleanly so dust stays out of the circuit.
Isolating a bottling-line drop during changeover
When a filler station is taken offline for format change, pushing a PP12D into its 12 mm supply socket keeps the header pressurised for the remaining stations without draining the ring main.
Capping robot arm air drops during maintenance
On a six-axis robot with end-of-arm tooling, a 12 mm drop left open after the gripper is removed can vent the whole circuit. The plug blanks it until the new tool is fitted.
Is the Airtac PP Pipe Plug PP12D the Right Part?
Dia 12 mm is the largest tube size the PP series is made in, so the only neighbouring size is PP10 one step down. Stepping from 10 to 12 buys you a bigger bore and a higher capacity branch, but it also means a larger socket on the manifold or tee, so check the port before ordering. There is no Dia 16 in this catalogue, so 12 mm is the end of the ladder.
Because the plug is inserted rather than threaded, it must meet a one-touch socket of exactly the same tube diameter. A PP12D will not lock into a Dia 10 or Dia 8 socket, and no adapter exists to fake the fit. If you need to close a threaded port instead of a tube socket, use the PM bulkhead union family or a threaded fitting with the port capped downstream.
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 PP12D FAQ
The PP12D is a one-touch tube plug for Dia 12 mm tubing. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure goes to -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the temperature range is -20 to +70 C. It takes soft nylon or polyurethane tube and the D suffix denotes the black version.
On PC and POC straight connectors the D only recolours the release button, but on the PP series the black finish applies to the plug body itself. Sealing hardware is identical either way: POM chuck and button, stainless spring gasket and NBR O-ring.
