About the Airtac PY Y-Type Tee Connector PY12
The PY12 is an AirTAC PY union Y from the resin one-touch line: a tube-to-tube branch with no thread at all. Its three ports all accept 12 mm OD soft nylon or polyurethane tubing, so one common stem feeds two legs that split off at an angle instead of the right-angle layout of a PE tee. Push each tube home and the internal chuck grips it; press the POM release ring and the tube frees off again.
This part runs on the resin spec profile: 0 to 1.0 MPa (0-10 kgf/cm2) working pressure, 1.5 MPa proof pressure, -20 to +70 C, and a vacuum rating of -750 mmHg (10 Torr), which many buyers overlook when planning pick-and-place circuits. Inside are a stainless spring gasket and an NBR O-ring; the standard body colour is grey, and the D suffix ordering option gives a black version instead.

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 PY Y-Type Tee Connector PY12 Is Used
Bottling line air knife split
A 12 mm supply trunk feeding twin air knives either side of a rinse tunnel can branch once with a PY12 instead of adding a threaded tee and two extra joints to seal.
Palletizer vacuum ejector feed
On palletizer heads the vacuum line to two ejectors often branches mid-run; the PY12's -750 mmHg (10 Torr) rating keeps the Y usable in the vacuum leg, not just the pressure side.
Conveyor gate cylinder pairing
Diverting conveyors commonly fire two 12 mm-port gate cylinders from one manifold drop; a Y union at the drop point balances the run lengths without a hard right-angle tee.
Is the Airtac PY Y-Type Tee Connector PY12 the Right Part?
PY12 sits at the top of the PY ladder, so the only step below it is PY10 - same Y shape on 10 mm tube, with a smaller bore and correspondingly lower volume flow. There is no Dia 16 union Y in this catalogue; if a 12 mm line is too small for the circuit, you split the flow with two unions or change the circuit design, not the fitting code.
All three ports take exactly 12 mm OD tube. A Dia 12 fitting will not hold 1/2 in (12.7 mm) hose or 10 mm tube - tube OD must match the fitting exactly, so re-check the printing on your tubing before ordering. If you need different diameters meeting at one point, look at the PEG, PEW or PYW different-diameter series instead, and PG if the change is in a straight run.
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 PY Y-Type Tee Connector PY12 FAQ
It is a resin one-touch union Y with three ports for 12 mm OD soft nylon or polyurethane tube and no thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr), temperature -20 to +70 C. Sealing is by stainless spring gasket and NBR O-ring, with a POM chuck and release ring.
No. All three ports of the PY12 grip exactly 12 mm OD tube - the code carries one diameter for the whole fitting. To step 12 mm down to 8 mm or 6 mm at a branch, use the different-diameter Y (PYW) or a different-diameter tee (PEG/PEW) instead, matching each port to its own tube OD.
