About the Airtac PYB Y-Type Threaded Tee Fitting PYB1001D-S
The AirTAC PYB1001D-S is a one-touch branch Y fitting that splits a single Dia 10 mm supply line into two branch legs off a male 1/8" PT thread. Push each tube home and the internal chuck grips it for a pressure-tight joint; press the release ring and the tube slides straight back out. The -S variant carries a SUS304 stud, while the body stays PBT in black, the finish chosen by the D suffix. Unlike the PC and POC straight connectors, where -S makes the whole body stainless, on the PYB family it is the threaded stud alone that becomes SUS304.
This is a resin-line fitting, so it runs at 0-1.0 MPa (0-10 kgf/cm2), handles vacuum down to -750 mmHg (10 Torr), carries a proof pressure of 1.5 MPa and works from -20 to +70 C with soft nylon or polyurethane tubing. These figures are identical to the grey standard version; the stainless stud changes the material, never the rating. The 1/8" thread arrives with sealant already applied, so it seals on a PT port without extra tape.

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 PYB1001D-S Is Used
Packaging machine branch feed
Splitting one manifold outlet into twoDia 10 branch lines feeding wrapper-tension cylinders on a horizontal flow-wrapper, where the Y angle routes tubing more cleanly than a tee.
Wash-down food conveyor air
Feeding two pneumatic gripper actuators on a tray-loading conveyor in a wash-down zone, where the SUS304 stud on the port side shrugs off daily caustic rinse far better than a plated brass stud.
Pick-and-place ejector supply
Branching the Dia 10 vacuum supply on a gantry pick-and-place cell to two Venturi ejectors, so both stations draw from one 1/8" threaded drop without a junction block.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1001D-S the Right Part?
On the 1/8" thread ladder for PYB, Dia 10 is the largest tube offered - the step down is PYB0801 (Dia 8), which frees panel space but halves the bore feeding your branches. To go larger than Dia 10 you must move up to a 1/4" thread: PYB1002 keeps the same tube on the bigger port, and PYB1202 takes you to Dia 12. Whichever you pick, the tube OD must match the fitting exactly - a Dia 10 Y will not grip 3/8" hose, and no adapter inside the fitting can fix that.
Choose a branch Y over a run tee when the two take-offs should leave at an angle rather than in-line, for example splitting feed to two legs of a gripper circuit. If your port is female, PLF or PED is the shape to look at instead.
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 PYB1001D-S FAQ
Working pressure 0-1.0 MPa (0-10 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 joins Dia 10 mm soft nylon or polyurethane tube to a male 1/8" PT thread, with a SUS304 stud and black PBT body. These ratings are exactly the same as the non-stainless PYB1001D.
No. On PYB-series -S parts AirTAC makes the threaded stud SUS304 while the body remains PBT, so the wetted port thread is what gains corrosion resistance. Only the PC and POC straight connectors in the -S line get a solid SUS304 body. Also note the grade is 304 only - AirTAC publishes no 316 version of this fitting.
