About the Airtac PP Pipe Plug PP6D
The AirTAC PP6D is a PP plug in the one-touch resin family: a Dia 6 mm tube socket with no thread behind it, used purely to blank off the end of a 6 mm line. Push the tube in and the internal chuck grips it; press the release ring and the tube comes free. There is nothing to thread up, so a plugged port is sealed in seconds and can be reopened later without cutting the tube.
PP6D carries the D suffix, which on this series makes the body black rather than the standard grey (on PC and POC connectors the D only changes the release button, so this is a real visual difference on the machine). The spec profile is the resin one: 0 to 1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C, with a POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring sealing the tube.

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 PP6D Is Used
Spare manifold outlets
Cap the unused Dia 6 outlets on a multi-station feeding manifold in a packaging machine so a future drop can be added without redesigning the air circuit.
Leak-test rig ends
Seal the Dia 6 tube ends of a test fixture holding a sealed enclosure or sensor housing during a 1.0 MPa pneumatic proof check, then release the tubes for the next unit.
Service blanking on robot cells
Blank a disconnected gripper line on a pick-and-place robot arm while the end effector is swapped, keeping the circuit sealed and the remaining stations running.
Is the Airtac PP Pipe Plug PP6D the Right Part?
PP plugs follow the same tube ladder as the rest of the resin range. One step down is PP4 for 4 mm line ends; one step up is PP8 for 8 mm, and 10 mm and 12 mm plugs exist above that. Stepping up gains flow capacity in the line you will later connect and a physically larger, more robust body; stepping down suits compact instrument tubing. Note that AirTAC also makes 3.2 mm tube, but only on the PC and PL mini series, so there is no 3.2 mm PP plug to choose.
A plug is not an adapter: it has no port thread at all, so it cannot join a line to anything. If you need to terminate into a threaded port instead, that is a job for a PC male connector of the same tube size. And as with every one-touch part, the tube OD must match exactly - a Dia 6 socket will not seal on 1/4 inch (6.35 mm) tube.
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 PP6D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The size is a Dia 6 mm tube socket with no thread. It takes soft nylon or polyurethane tubing only, and the black body is the D-suffix version of the standard grey PP6.
No. The PP6D accepts Dia 6.0 mm outside-diameter tube only. 1/4 inch tube measures about 6.35 mm, which is enough oversize for the chuck not to seal properly. Use the matching plug size for the exact tube you are running, and remember the plug has no thread, so it caps a line rather than adapting it to a port.
