About the Airtac PYB Y-Type Threaded Tee Fitting PYB801
The PYB801 is an AirTAC PYB branch Y, a threaded one-touch fitting that turns a single 1/8in PT male port into two Dia 8 mm tube outlets set at a Y angle. Push each soft nylon or polyurethane tube into its chuck until it bottoms out and the internal gripper holds it against the 1.5 MPa proof pressure; press the POM release ring to let the tube go. The male thread arrives with sealant already applied, so it seals straight into a PT-tapped manifold or valve port without extra tape.
This is the resin one-touch spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), and a service temperature of -20 to +70 C. The standard body colour is grey; ordering the PYB801D swaps the whole body to black, not just the release button, which matters on machines where colour-coded circuits identify vacuum versus pressure lines.

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 PYB801 Is Used
Twin gripper feed on a palletiser
One 1/8in solenoid outlet can serve two suction or clamp cylinders by fitting a PYB801 Y at the port, splitting the supply into two Dia 8 runs of equal length so both grippers act at the same rate.
Distribution take-off on a conveyor guarding line
Where a conveyor control valve feeds both the reject blast and the product stop, the Y geometry routes two Dia 8 tubes off one threaded port inside tight guarding without adding a second valve station.
Branch point on a control cabinet sub-plate
Mounted into a pre-tapped 1/8in PT hole on a machine sub-plate, the PYB801 creates a clean two-way split for Dia 8 nylon tubing running to panel-mounted indicators or small actuators.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB801 the Right Part?
On the PYB ladder at 1/8in PT, the neighbours are Dia 6 below and Dia 10 above. Stepping down to PYB601 suits lighter cylinder and sensor feeds where the smaller bore keeps the circuit responsive; stepping up to PYB1001 moves more air to larger actuators on the same 1/8in port. Note the PYB also exists in 1/4in, 3/8in and 1/2in threads and in M5 for Dia 4 and Dia 6 only, so check the port thread before fixing the tube size. Whichever you choose, the tube OD must match exactly: a Dia 8 Y will not grip 5/16in or 1/4in tube. If you need two branches from a panel wall instead of a port, the PM bulkhead connector is the shape for that job.
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 PYB801 FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure goes to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the service temperature range is -20 to +70 C. This SKU joins Dia 8 mm soft nylon or polyurethane tube to a 1/8in PT male thread, and it belongs to the resin one-touch family, not the 0.9 MPa / 150 C metal BP line.
No. Both outlets of the PYB801 grip Dia 8 tube only; the chuck and O-ring are sized for that one OD. To step a circuit down or up, keep the PYB for the split and put a PG different-diameter straight union in one leg, or move to a PKG reducer triple branch union if you want the reduction built into the branch itself.
