About the Airtac PYB Y-Type Threaded Tee Fitting PYB1001
The PYB1001 is AirTAC's branch Y one-touch fitting: a Y-shaped body that puts a 1/8 in PT male threaded branch onto two Dia 10 mm push-in tube ports. Push each tube home and the internal chuck grips its OD; press the POM release ring and the tube frees off again without tools.
This is the resin line, not the metal BPC family: working pressure 0-1.0 MPa, vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a -20 to +70 C temperature window. The 1/8 in male branch arrives with sealant already applied, so it threads straight into a PT port and seals on assembly.

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 PYB1001 Is Used
Indexing table valve outlet splitter
On a small rotary indexing table, the valve outlet feeds a clamp cylinder and an air-assist nozzle at different angles. The Y branch takes one 1/8 in port and splits it into two 10 mm tube runs without adding a tee block or a second valve.
Bench capping machine supply take-off
A bench-top bottle capper runs two 10 mm lines - one to the capping head, one to the bottle-grip pad - from a single regulator outlet. A threaded Y at the regulator keeps both legs at the same pressure and halves the plumbing in a cramped frame.
Lab automation pneumatic distributor
In a compact liquid-handling station, a 1/8 in PT port on the solenoid manifold feeds aspirate and purge lines. The Y branch splits that port into two 10 mm polyurethane runs with a push-in connection that survives repeated panel service.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1001 the Right Part?
On the 1/8 in thread, the PYB ladder runs Dia 4, 6, 8, 10 - so PYB1001 sits at the top of that rung. Step down to PYB801 if your circuit is on 8 mm tube and you want lower push-in insertion force and a smaller body footprint. There is no Dia 12 version on a 1/8 thread; the next step up in bore is PYB1202 on a 1/4 in port, which also gives a stiffer branch stud.
Match the thread to a PT port or use a thread adapter - this catalogue documents PT only, with no G or NPT ordering code. And match the tube exactly: the Dia 10 chuck will not seal on 3/8 in or 1/4 in Imperial tube, so measure the OD before you order.
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 PYB1001 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability down to -750 mmHg (10 Torr), and a working temperature of -20 to +70 C. The tube ports take Dia 10 mm soft nylon or polyurethane tubing and the branch thread is 1/8 in PT male with factory-applied sealant.
No. Both push-in ports on the PYB1001 are Dia 10 mm chucks, and tubing must match the rated OD exactly - a Dia 10 chuck will not grip 8 mm or 12 mm tube. If your two legs differ in size, split at the larger bore and reduce downstream with a PG reducer or a different-diameter fitting instead.
