About the Airtac PYB Y-Type Threaded Tee Fitting PYB1202
The PYB1202 is an AirTAC PYB branch Y: a male-threaded one-touch fitting that takes a single 1/4in PT port and splits it into two Dia 12 mm tube legs set at a Y angle. Push each tube straight into its chuck and the stainless spring gasket grips it for a sealed joint; press the POM release ring and the tube slides straight back out for rework or re-routing.
It runs on AirTAC's resin spec profile: 0 to 1.0 MPa working pressure (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), 1.5 MPa proof pressure and -20 to +70 C. The body is PBT on a brass stud, the thread arrives pre-coated with sealant, and the standard colour is grey (a D suffix would give black). With 12 mm bore on both legs, this is the large-end member of the PYB ladder for main air distribution.

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 PYB1202 Is Used
Robot gripper supply split
On a robotic pick-and-place wrist, a single 1/4in drop from the end-of-arm valve block splits at the PYB1202 into two Dia 12 legs feeding parallel pneumatic grippers, with no extra tee body to snag in the cage.
Palletiser clamp manifold branch
A palletiser's clamp beam carries one 1/4in PT run; the PYB1202 branches it into two 12 mm lines serving the side-clamp and hold-down cylinders, both legs releasing from the same fitting when the beam is rebuilt.
Twin blow-off nozzles on a filling line
A bottled-water line uses one 1/4in feed to drive two air knives either side of the conveyor; the PYB1202 splits the supply at the frame so each Dia 12 leg reaches its nozzle without a junction box.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1202 the Right Part?
At a 1/4in PT thread, Dia 12 is the largest tube the PYB accepts - there is no size above it on this port. Step down instead to PYB1002 (Dia 10 tube) if your actuators are on 10 mm line; the smaller bore suits lighter-consuming legs but starves big cylinders sooner. If the port itself is 3/8in, the same 12 mm tube is available as PYB1203, which moves the choice onto the thread rather than the bore.
Match the 1/4in PT male stud to the actual port spec before ordering, and remember tube OD must match exactly: a Dia 12 Y will not seal on 1/2in or 10 mm tube. If the two legs need different bores, the different-diameter series (PYW) is the correct route, not this fitting.
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 PYB1202 FAQ
Working pressure 0 to 1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The part is a Dia 12 mm one-touch branch Y with a 1/4in PT male thread, grey PBT body on a brass stud, with thread sealant pre-applied. Use soft nylon or polyurethane tube sized exactly Dia 12.
No. Both legs of the PYB1202 grip Dia 12 mm tube only - the chuck set is a single size, and tube OD must match the fitting exactly or it will not seal or release properly. For a branch that steps down to a smaller bore, use a different-diameter Y such as the PYW series, which carries both sizes in its code.
