About the Airtac PYB Y-Type Threaded Tee Fitting PYB1202D
The PYB1202D is an AirTAC PYB branch Y, a threaded one-touch fitting that turns a single 1/4in PT male port into two Dia 12 mm tube legs set at a Y angle. The body is PBT with a brass stud, and on this series the D suffix means the body itself is moulded black rather than the standard grey, which keeps the fitting identifiable against black machine frames and dark panels. The male thread arrives with sealant already applied, so it goes straight onto a PT port without extra tape.
Connection is the usual one-touch action: push each 12 mm soft nylon or polyurethane tube into its socket until it bottoms, and the internal chuck grips the tube wall against the stainless spring gasket and NBR O-ring. Press the POM release ring toward the body to free a tube. As a resin-series part it is rated 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C.

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 PYB Y-Type Threaded Tee Fitting PYB1202D Is Used
Twin ejector feeds on tray sealers
One 1/4in outlet on a food tray-sealing machine's valve manifold splits into two Dia 12 legs feeding a pair of vacuum ejector modules, replacing a separate tee and nipple.
Dual cylinder drops on palletisers
A single PT drop down a palletising gantry is branched at the Y to supply two clamp cylinders side by side, keeping the plumbing to one fitting per level.
Paired nozzles on humidification lines
Textile plant misting manifolds use the Y to feed two Dia 12 mist nozzle lines from one threaded branch, with the black body standing out against grey ducting.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1202D the Right Part?
On the 1/4in thread rung of the PYB ladder, Dia 12 is the largest tube offered, and the step down is Dia 10; both branches of this Y are always the same OD, so a mixed 12/10 split is not a catalogue option. If you need a smaller feed into one leg, put a PG reducer union in the line. If your port is 3/8in or 1/2in PT, PYB exists there too and both rungs still carry Dia 12, so you can often keep the tube size and only change the thread digit.
Match the Y to the port, not the tube: a 1/4in PT stud suits standard manifold and valve outlets, while the twin Dia 12 legs each carry roughly the full bore of a single 12 mm line, so flow splits across two legs rather than necking down. Check that both destination tubes are genuinely 12 mm OD; a Dia 6 tube pushed into this socket will not seal.
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 PYB Y-Type Threaded Tee Fitting PYB1202D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It accepts Dia 12 mm soft nylon or polyurethane tube in both Y legs, on a 1/4in PT male thread, and the D suffix gives a black PBT body with brass stud. Do not exceed 70 C: above that the tubing, not the fitting, becomes the limit.
No. Both branches of a PYB are machined for the same OD, so the PYB1202D grips 12 mm tube in each leg. If one downstream circuit needs a smaller line, run 12 mm to a PG different-diameter straight union or a PGJ plug-in reducer and step down there. Also note the PT thread carries pre-applied sealant, so hand-tighten onto the port without adding tape.
