About the Airtac PYB Y-Type Threaded Tee Fitting PYB801D-S
The PYB801D-S is an AirTAC PYB branch Y in the resin one-touch range, finished in black (the D suffix) and built with a SUS304 stainless stud. It turns one 1/8" PT male thread into two Dia 8 tube legs angled in a Y, so a single threaded port can feed two air lines without adding a separate tee and union.
This is the standard resin spec profile, not the metal BP line: 0-1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and -20 to +70 C. Push soft nylon or polyurethane tube into each leg until it bottoms; the internal chuck grips it, and pressing the release ring frees it again. The 1/8" stud arrives with sealant already applied, and the SUS304 stud resists corrosion at the threaded joint where plated brass would gradually degrade in humid or wash-down surroundings.

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 PYB801D-S Is Used
Pick-and-place gantry split feed
One 1/8" drop from the manifold valve bank feeds two Dia 8 lines running out to a pair of small bore air cylinders on a pick-and-place gantry, keeping the plumbing down to a single fitting at the drop point.
Panel-mounted valve output splitter
On a machine control panel, the 1/8" PT stud screws into the outlet of a solenoid valve and the two Y legs carry Dia 8 tube to left and right actuators, avoiding a loose tee joint behind the panel.
Carton erector suction supply
A carton-erecting station on a packaging line uses the Y branch to split one vacuum-rated supply into two Dia 8 lines serving suction cups on either side of the flap, since the fitting holds -750 mmHg.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB801D-S the Right Part?
On the 1/8" thread row of the PYB ladder, this Dia 8 part sits between PYB601 (Dia 6 tube, tighter bore, less flow area per leg) and PYB1001 (Dia 10 tube, the largest the 1/8" thread supports before you must move to a 1/4" or 3/8" stud). Step down for compact actuators and short runs, up when both legs feed cylinder ports over longer distance. If you need the same Y split but between tubes with no threaded port at all, that is the PY801 union Y instead.
Match the stud to the port it enters and note the branch legs take Dia 8 tube only - a 6 mm or 1/4" tube will not seat in the chuck. The stainless variant changes the stud material, not the ratings or dimensions, so it drops straight into the same design as the standard PYB801.
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 PYB801D-S FAQ
It is a PYB branch Y with a 1/8" PT male stud and two Dia 8 one-touch tube legs, in black PBT with a SUS304 stainless stud. Working pressure is 0-1.0 MPa, negative pressure -750 mmHg, proof pressure 1.5 MPa, and working temperature -20 to +70 C with soft nylon or polyurethane tubing. The stud arrives with thread sealant applied.
The PYB carries a male threaded leg, so it screws straight into a valve, cylinder or manifold port and then splits into two tube lines. The PY801 union Y is tube-to-tube only, with three push-in legs and no thread. Use PYB when one end of your Y must land on a threaded port; use PY when all three connections are tube runs.
