About the Airtac PE Tee Connector PE12
The PE12 is an AirTAC PE union tee, a tube-to-tube one-touch fitting with three Dia 12 mm ports and no external thread at all. It exists to split a 12 mm air line into two branches of the same bore, or to merge two returns into one, without adapters, compression rings or spanners. Push the tube in and the internal chuck grips the OD; press the release ring toward the body and the tube slides straight back out.
PE12 sits at the top of the resin one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. The body is PBT with a POM release button and chuck, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring. With a 12 mm bore feeding all three legs, this is the highest-capacity tee in the PE ladder, so treat it as a trunk fitting rather than a drop-fitting at the actuator.

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 PE Tee Connector PE12 Is Used
CNC machine air drop manifold
On a machining centre with a single 12 mm feed from the FRL, a PE12 teed into the drop line splits supply between the spindle-area blast nozzle and the way-lube purge circuit without breaking into threaded pipe.
Twin-cylinder feed on a carton sealer
Packaging machinery often fires two flap-tucking cylinders in sync. A PE12 at the branch point gives both actuators the same 12 mm supply leg, keeping their stroke timing matched.
Vacuum header on a pick-and-place cell
Rated to -750 mmHg (10 Torr), the PE12 also works as a suction-side tee, joining two suction-cup return lines from a sheet-gripping end effector into one 12 mm line back to the venturi.
Is the Airtac PE Tee Connector PE12 the Right Part?
Step down to PE10 and you lose 2 mm of bore on every leg, which is exactly the difference you feel at the end of a long run, so PE12 is the right call wherever the tee sits close to the source and carries the main flow. There is no larger union tee in this catalogue: Dia 12 is the end of the PE ladder, and anything bigger is not made here.
Because all three ports are tube sockets, match your tubing OD exactly: a Dia 12 socket will not seal or hold 1/2 in (12.7 in nominal) tube, and it will not grip a 10 mm line. If you actually need to screw the tee onto a threaded port instead, that is a PED male run tee, not this part. Soft nylon or polyurethane tubing only.
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 PE Tee Connector PE12 FAQ
It is a one-touch union tee with three Dia 12 mm tube ports and no thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, working temperature -20 to +70 C. Tubing must be soft nylon or polyurethane, and the fitting arrives in grey as standard.
Yes on both counts. The resin one-touch profile is rated down to -750 mmHg (10 Torr), so suction service is inside spec. All three sockets are Dia 12 only: the chuck and O-ring are sized for that exact OD, so every leg must run 12 mm nylon or polyurethane tube. To join different diameters you would need a different-diameter tee from the PEG or PEW families instead.
