About the Airtac PYW Y-Type Reducing Tee Fitting PYW12-10D
The PYW12-10D is an AirTAC different diameter union Y: a one-touch, tube-to-tube fitting with no thread at all. Its single run leg grips Dia 12 soft nylon or polyurethane tubing, while the two angled branches grip Dia 10, letting one supply line split into two smaller drops without a manifold block. The D suffix makes the entire body black; on this series the colour code changes the body itself, unlike the PC and POC connectors where it changes only the release button.
Each of the three ports works identically: push the tube home and the chuck grips the outside diameter while an NBR O-ring seals it, and pressing the release ring frees the tube again. This is the resin one-touch profile, not the metal line: 0-1.0 MPa working pressure, 1.5 MPa proof, -20 to +70 C, and it also holds -750 mmHg, so the same fitting serves vacuum take-off lines as well as pressure.

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 PYW Y-Type Reducing Tee Fitting PYW12-10D Is Used
Palletiser vacuum take-off
Split the Dia 12 line running from a vacuum generator into two Dia 10 drops feeding twin suction-cup frames on a palletising head; the -750 mmHg rating means the fitting holds on the vacuum side, not just under pressure.
Carton sealer cylinder feed
Branch a Dia 12 ring main above a packaging line into two Dia 10 runs, one to the flap-fold clamp cylinder and one to the seal-head cylinder, with a single push-fit joint instead of a fabricated tee block.
Colour-coded circuit in a CNC cell
The all-black body marks this as the dedicated high-consumption blast circuit behind a machining centre, so technicians tracing lines in a crowded cabinet do not confuse it with the grey control-air circuits.
Is the Airtac PYW Y-Type Reducing Tee Fitting PYW12-10D the Right Part?
Dia 12 is the largest tube this catalogue offers, so there is no step up from this SKU; the smaller PYW pairings step the branch side down in 2 mm increments toward Dia 4. Each step down trades branch flow capacity for a smaller, cheaper downstream run, so size the branches from the actual air consumption of the two loads they feed rather than from the trunk diameter. There is no thread to match to a port here; if the split must land on a threaded port instead, the PED male run tee is the threaded counterpart in the same family.
Whatever you order, tube OD must match exactly: the Dia 12 leg will not hold 1/2 inch tube, which measures 12.7 mm and is too large for the chuck, and the Dia 10 branches will not grip 3/8 inch tube either.
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 PYW Y-Type Reducing Tee Fitting PYW12-10D FAQ
It is a resin one-touch different diameter union Y with no thread, joining one Dia 12 mm run leg to two Dia 10 mm branches. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr) and temperature range -20 to +70 C. Tubing must be soft nylon or polyurethane, and the D suffix gives a black body.
No on both counts. The chucks are sized to metric outside diameters only, so a Dia 12 leg will not grip 1/2 inch tube (12.7 mm) and the Dia 10 branches will not grip 3/8 inch tube. There is also no threaded port on this fitting; if you need to land the split on a thread, use the PED male run tee from the same one-touch family instead.
