About the Airtac PYB Y-Type Threaded Tee Fitting PYB401
The AirTAC PYB401 is a PYB branch Y in the resin one-touch range: a threaded Y fitting that takes one 1/8in PT male port and splits the supply into two Dia 4 mm tube legs set at a Y angle. Push each soft nylon or polyurethane tube into its socket and the internal chuck grips it; press the release ring and the tube slides straight back out, no tools needed.
Like every P-prefix fitting in this catalogue it works from 0 to 1.0 MPa (0 to 10 kgf/cm2), holds vacuum down to -750 mmHg (10 Torr), carries a 1.5 MPa proof pressure and runs at -20 to +70 C. The Y body is PBT on a brass stud and arrives with sealant already on the PT thread, so it is ready to wind in 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 PYB401 Is Used
Manifold sub-plate feeds
One 1/8in PT outlet on a small valve manifold splits into two Dia 4 drops with the Y instead of a tee plus elbow, keeping the sub-plate wiring and tubing loom tight.
Microplate handler vacuum cups
Benchtop lab automation lifting microplates with twin small cups can run one vacuum line in and feed both cups from the PYB401's paired Dia 4 legs, inside the -750 mmHg rating.
Parts-ejection air jets
A bench assembly cell nudging finished parts off a fixture with two short air jets can share a single 1/8in port through this Y, with the angled legs following the fixture geometry.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB401 the Right Part?
Dia 4 is the smallest tube AirTAC makes on the PYB ladder, so there is nothing below it; step up to Dia 6 on the same 1/8in thread and the PYB601 feeds twice the bore for slightly hungrier actuators. If your port is an M5 boss instead, the PYB4M5 keeps the same Dia 4 legs and seals with a gasket rather than taper thread, while PYB402 moves the same Y onto a 1/4in port. Whatever you choose, the tube OD must match exactly - a Dia 4 socket will not seal on 6 mm or 1/4in tube.
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 PYB401 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. The part is a PYB branch Y fitting for Dia 4 mm tube on a 1/8in PT male thread, standard grey body, resin PBT construction on a brass stud.
No. AirTAC ships PYB threaded fittings with sealant already applied to the PT taper thread, so it can be wound straight into the port. The M5 versions in the same family are the exception - they seal with a gasket instead. Just keep the release rings clear so you can still push the Dia 4 tubes home after installation.
