About the Airtac PYB Y-Type Threaded Tee Fitting PYB1004D-S
The PYB1004D-S is an AirTAC branch Y one-touch fitting in the black colour variant. It takes one threaded inlet - 1/2in PT on the stud - and splits the supply into two Dia 10mm tube lines set at an angle, which is the difference from a run tee: the branches leave the body at a Y rather than straight across, so the two legs clear each other in tight pipework. To connect, push the soft nylon or polyurethane tube straight into the port; the stainless spring gasket and internal chuck grip the OD, and pressing the POM release ring frees it again. On this stainless variant the PBT body stays as standard and the 1/2in stud is SUS304 - the geometry and dimensions are identical to the grey PYB1004.
This is the resin/brass spec profile, and the ratings must not be confused with the metal BPC line: working pressure 0 to 1.0 MPa, negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The threaded stud arrives with sealant already applied, so it seals on the PT taper without extra tape. Note that no Dia 10 tube size other than exactly 10mm OD will lock into these ports.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PYB1004D-S Is Used
Twin pneumatic grippers on a robot end-of-arm
One 1/2in PT supply drop to the wrist splits at the Y into two Dia 10 legs feeding open and close circuits of a large gripper, keeping the branch compact at the tool flange.
Paired blow-off nozzles on a bottling line
The Y takes a single feed and branches it to two Dia 10 lines running jets that clear water and label scraps from bottles entering a date coder.
Manifold outlet splitting to two machine axes
The SUS304 1/2in stud threads into a valve manifold station port; the two branches each carry Dia 10 tube out to slide cylinders on adjacent stations of a rotary indexing table.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1004D-S the Right Part?
Size ladder around this SKU, all on the same 1/2in thread: one step down is PYB804 on Dia 8 tube, one step up is PYB1204 on Dia 12. Stepping down frees panel space and suits lighter actuator loads; stepping up cuts air speed in the leg for longer runs. If the port on the valve or manifold is 3/8in rather than 1/2in, PYB1003 is the matching part - 3/8in on this prefix supports Dia 10, so the tube side does not change. What never changes is the tube rule: a Dia 10 port holds only Dia 10 tube, so a 3/8in or 12mm hose will not seat past the chuck.
Pick the Y shape over a bulkhead or universal elbow when two consumers of roughly equal demand hang off one supply port - a twin-cylinder station, two blow-off points, paired ejectors. A PH swivel elbow is the better answer if you need one line to rotate into alignment instead of branching in two.
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 PYB1004D-S FAQ
This branch Y fits Dia 10mm tube on both outlets and a 1/2in PT threaded stud, with the stud made of SUS304 stainless steel and the body PBT. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and the service temperature range is -20 to +70 C. It is designed for soft nylon or polyurethane tubing only.
No. Both ports are Dia 10 only - the chuck and gasket are sized to one OD, so 8mm or 12mm tube will not seal here. If you need to drop the line size, keep Dia 10 to the Y and add a PG10-8 different-diameter straight union on each leg, or select the PKG reducer triple branch if the whole branch can be redesigned. For the same function at a different thread, PYB1003 gives you 3/8in PT instead of 1/2in.
