About the Airtac PYB Y-Type Threaded Tee Fitting PYB1203D
The PYB1203D is an AirTAC PYB branch Y in the black (D suffix) finish: a one-touch fitting that takes a single 12 mm tube into one leg and sends the airflow out through two angled branch legs, with the supply entering from a 3/8in PT male thread. Push the tube into the port and the internal chuck grips it straight away; press the release ring and the tube comes free, so branch changes take seconds with no tools on the tube side.
This is the resin/brass one-touch profile, not the metal BP line: 0 to 1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The threaded parts are PBT with a brass stud and arrive with sealant already on the thread, and on PYB parts the D suffix changes the whole body colour to black, not just the release button.

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 PYB1203D Is Used
Twin pneumatic clamps on a press jig
One 3/8in drop from the manifold feeds two Dia 12 clamp cylinders mounted side by side; the Y's shallow branch angle keeps the two tube runs clear of each other inside the jig frame.
Pallet wrapper carriage air feed
The rotating carriage of a stretch wrapper needs air split to a grip cylinder and a cut-and-clamp cylinder; a single Dia 12 trunk on the slip ring taps into the PYB1203D's 3/8in threaded leg and both functions run off the one line.
Woodworking gate actuator split
A dust-extraction blast gate on a workshop router table shares one supply with its gate cylinder; the Y lets one 3/8in PT port from the valve feed both the Dia 12 actuator line and a second branch without a tee block.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1203D the Right Part?
Dia 12 is the top of the PYB tube ladder, so the only step down on this prefix is PYB1003D at Dia 10 - the same 3/8in thread but a smaller bore, which limits the air you can feed each branch. Stepping up on this SKU means going to a bigger thread instead: PYB1204D keeps the Dia 12 tube but moves the supply port to 1/2in PT, and PYB1202D drops to 1/4in PT if the manifold port is smaller. A Y splits flow at a shallower angle than a PED run tee, so the two branch tubes leave the body with more clearance between them - handy when both legs feed cylinders mounted side by side. Whatever you order, the tube OD must be exactly Dia 12; a fitting bored for 12 mm will not seal on 1/2in nominal hose.
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 PYB1203D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The fitting joins Dia 12 mm soft nylon or polyurethane tube on the push-in legs and has a 3/8in PT male thread on the supply leg, supplied in black with sealant pre-applied to the thread.
No. AirTAC ships all threaded one-touch parts with sealant already on the thread, so the 3/8in PT stud can be wound straight into the port. M5 sizes in this catalogue are the exception - they seal with a gasket instead - but this SKU is a standard 3/8in PT part. Screw it in hand-tight and seat it against the port; do not back the fitting off to re-align the branch legs, as that can break the seal.
