About the Airtac PYB Y-Type Threaded Tee Fitting PYB802D-S
The PYB802D-S is an AirTAC one-touch branch Y: a single male 1/4in PT thread branches into two Dia 8mm tube outlets set at a Y angle, so one port on a valve, manifold or cylinder can feed two lines without adding a tee plus a union. The -S variant fits a SUS304 stainless stud into the threaded port while the body stays glass-filled PBT finished in black, the colour the D suffix selects on this series.
Connection takes seconds: push each 8mm tube into its socket and the internal chuck grips it for a pressure-tight seal, then press the release ring to free it. This is the resin spec profile, not the metal line: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C with soft nylon or PU tubing. The PT thread arrives with sealant already applied; the internal O-ring is NBR, the release ring and chuck are POM, and the guide is aluminium alloy.

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 PYB802D-S Is Used
Valve manifold feed split
On a packaging machine's valve manifold, the stainless stud threads into one 1/4in outlet and the Y legs carry 8mm tubing to two downstream cylinders, halving the manifold ports needed.
Twin-gripper robot end of arm
A pick-and-place arm with two suction or clamping grippers takes one air feed through the SUS304 stud and branches it to both actuators in a single compact part.
Air knife pair on a wash line
A food-plant rinse station feeds two 8mm nozzle lines from one supply port, with the stainless stud standing up to humid wash-down surroundings.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB802D-S the Right Part?
On the 1/4in thread row, PYB runs from Dia 4 up to Dia 12, so this Dia 8 sits between the PYB602 and the PYB1002. Stepping down to 6mm lightens the assembly and suits compact actuators; stepping up to 10mm halves resistance on longer runs to high-consumption cylinders. The two tube legs of a branch Y share one supply, so size the bore for the combined flow of both lines rather than each branch alone.
Tube OD must match exactly - an 8mm socket will not grip 6mm or 1/4in tube. If you actually need to pass the fitting through a panel wall and lock it, the bulkhead families (PM or PLM) are the right shape instead; the PYB mounts on the external thread of the stud only.
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 PYB802D-S FAQ
Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum down to -750 mmHg, and proof pressure 1.5 MPa. Temperature range is -20 to +70 C with soft nylon or polyurethane tubing. This SKU is a Dia 8mm branch Y with a 1/4in PT male thread and a SUS304 stud in a black PBT body.
No. On the PYB family the -S option fits a SUS304 stainless stud, which is the part that screws into your port, while the body remains PBT, here in the black D-suffix finish. The internal O-ring stays NBR and every pressure, vacuum and temperature figure is identical to the standard PYB802D, so there is no need to re-rate anything downstream.
