About the Airtac PY Y-Type Tee Connector PY12D
The PY12D is a black-bodied one-touch union Y from AirTAC: a three-legged connector with no external thread, used purely to split one 12 mm tube run into two, or to merge two runs back into one. Both branch legs take Dia 12 tubing, and because it is a Y rather than a tee, the flow changes direction through a smoother, more gradual junction. The D suffix gives the whole body a black finish rather than the standard grey, which helps on machines where black fittings are specified for appearance or uniformity.
Connection is the standard one-touch action: push the soft nylon or polyurethane tube past the POM chuck and it grips firmly on the stainless spring gasket seat; press the release ring and the tube slides free. As a resin-series part it is rated 0 to 1.0 MPa (0 to 10 kgf/cm2), handles vacuum down to -750 mmHg (10 Torr), and works from -20 to +70 C. Dia 12 is the largest bore in this resin one-touch range, so this is the fitting to reach for when volume, not size, is the constraint.

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 PY12D Is Used
Bottling line air knives
Split the 12 mm feed from a single drop so two blow-off air knives clear bottles on both sides of the conveyor without a second regulator tap.
Twin vacuum ejector supply
Feed two ejector pumps from one 12 mm supply line on a pick-and-place cell; the Y keeps the upstream run short and the vacuum rating of -750 mmHg covers it.
Manifold drop to paired cylinders
Branch one 12 mm manifold outlet out to two larger-bore actuators on a press fixture, with the black body blending in on dark machine frames.
Is the Airtac PY Y-Type Tee Connector PY12D the Right Part?
Dia 12 is the top of the ladder: the only neighbouring size below is PY10, which drops the bore for tighter spaces or lighter-air branches. There is no Dia 16 one-touch union Y in this catalogue - PY12D is the biggest you can buy here - so anything larger needs a hard-piped or threaded branch instead. Matching matters both ways: a Dia 12 leg will not seal on 1/2 inch (12.7 mm) tube, and mixing sizes on one Y is not what this part does; the PZW different-diameter family exists for that job. If you need to mount the split through a panel, look at PM bulkhead union or PLM bulkhead male elbow rather than forcing a Y behind a wall.
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 PY12D 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, and a temperature range of -20 to +70 C. Both legs accept Dia 12 mm soft nylon or polyurethane tube and there is no thread - it is a tube-to-tube union Y. The body is black (D suffix) with POM release button and chuck, aluminium-alloy guide and NBR O-ring.
No. The PY12D grips Dia 12 tube on all three legs - tube OD must match the fitting exactly or the chuck will not seal. For different diameters, AirTAC makes the PYW different-diameter union Y; check that family instead. Also note the vacuum and pressure ratings above apply to the resin line - they are not the same as the metal BP series.
