About the Airtac PYB Y-Type Threaded Tee Fitting PYB1002
The PYB1002 is an AirTAC PYB branch Y one-touch fitting: it screws into a 1/4in PT threaded port and divides that single air supply into two Dia 10 mm push-in tube lines running off at an inclined Y angle. Where a tee sends a branch out sideways at 90 degrees, the Y carries both lines off the port in a shallower spread, which is often the only way to route two runs out of one valve outlet inside a cramped manifold or guard.
This is the resin and brass one-touch family, rated 0-1.0 MPa (0-10 kgf/cm2), with a proof pressure of 1.5 MPa and a working temperature of -20 to +70 C. To connect, push the Dia 10 mm soft nylon or polyurethane tube straight in until it bottoms: the stainless spring gasket and POM chuck grip it immediately, and pressing the release ring frees it again. The 1/4in PT thread arrives from AirTAC with sealant already applied, so it seals without extra tape.

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 PYB1002 Is Used
Twin-finger pneumatic gripper
One 1/4in PT valve outlet on a pick-and-place robot can feed both finger cylinders of a parallel gripper - the Y splits the supply into two Dia 10 mm lines that follow the wrist into the work envelope.
Manifold branch divider
On a packaging machine's air preparation manifold, a single 1/4in PT tap can be divided into two equal Dia 10 mm tube runs, one for the machine frame circuits and one for the tooling, without adding a second threaded port.
Textile machine jet supply
Looms and spinning frames run many small air jets from few ports; a PYB1002 at a 1/4in PT outlet pushes two 10 mm nylon lines out along the frame at a gentle spread instead of a hard right angle, easing routing along curved machine sections.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1002 the Right Part?
This SKU sits mid-ladder on both axes. On the thread side, PYB1001 steps down to a 1/8in PT port and PYB1003 steps up to 3/8in - note that AirTAC caps the 1/8in PYB at Dia 10 mm tube, so this 1/4in part is the smallest thread that still opens the door to a Dia 12 upgrade later. On the tube side, PYB0802 branches into two 8 mm lines for lighter actuators and PYB1202 into two 12 mm lines for higher-demand circuits.
Match the 1/4in thread to a port actually tapped 1/4in PT; on reducers and reducers only do the sizes split, never here. And remember that the Dia 10 mm bore is fixed: a 10 mm fitting will not grip 5/16in or 3/8in hose, because the chuck and NBR O-ring are machined for exactly 10 mm outside diameter.
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 PYB1002 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. The fitting accepts Dia 10 mm soft nylon or polyurethane tube on both push-in legs and mounts on a 1/4in PT male thread. It belongs to the resin and brass one-touch series, with a grey PBT body and brass stud, and the PT thread is supplied pre-coated with sealant.
No. Both push-in legs of a PYB branch Y accept the same tube OD as the code, here Dia 10 mm - the chuck, spring gasket and NBR O-ring are sized for exactly 10 mm and will not seal on 8 mm or 12 mm hose. If you need to step sizes down at the branch, use the PKD male reducer triple branch family instead, which combines a threaded port with a smaller branch tube diameter in one part.
