About the Airtac PYB Y-Type Threaded Tee Fitting PYB601D-S
The PYB601D-S is an AirTAC PYB branch Y, a resin one-touch fitting that turns a single 1/8 in PT male thread into two Dia 6 mm tube outlets set at a Y angle. Push each soft nylon or polyurethane tube home into the chuck and the grip ring holds it; press the release ring and the tube slides free for rework. The thread arrives from AirTAC with sealant already applied, so the stud seals straight into the port without extra tape.
This part sits on the resin and brass spec line, not the metal BP family: working pressure 0 to 1.0 MPa, proof pressure 1.5 MPa, vacuum to -750 mmHg and a temperature window of -20 to +70 C. The D suffix makes the body black rather than grey, and the -S option swaps in a SUS304 stud for ports exposed to wash-down or splash. On this family only the stud is stainless; the body stays PBT and every rating stays exactly the same as the standard grey version.

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 PYB601D-S Is Used
Dairy filling line wash-down zone
Split a single 1/8 in valve outlet into a Dia 6 gate cylinder line and a Dia 6 blow-off jet on the filling conveyor, with the SUS304 stud standing up to daily hose-down where a plain brass stud would corrode.
Screen-printing press manifold
Feed two Dia 6 squeegee-lift cushions from one PT 1/8 port when fitting two separate elbows would crowd the valve manifold; the Y angle routes both branches clear of adjacent fittings.
Marine instrument enclosure purge
Branch dry compressed air from one stud into two Dia 6 vent lines inside a splash-exposed navigation enclosure, the black body blending with the panel hardware and the stainless stud resisting salt-air attack.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB601D-S the Right Part?
On the PYB 1/8 in ladder the available bores are Dia 4, 6, 8 and 10, so PYB401D-S steps down one size and PYB801D-S steps up; note the ladder stops at Dia 10, so a Dia 12 branch on 1/8 thread is not offered and you would move to PYB1202 on a 1/4 in port instead. If the thread is the variable and the bore is fixed, PYB6-M5 drops to an M5x0.8 stud and PYB602D-S rises to 1/4 in. A Y is the right shape when two branch lines must leave one supply at an angle; pick PED for a 90 degree run tee or PM bulkhead for a panel pass-through. Match tube OD exactly: a Dia 6 socket will not hold 1/4 in tube.
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 PYB601D-S FAQ
It is a PYB branch Y one-touch fitting with a Dia 6 mm tube socket on each branch and a 1/8 in PT male thread. Working pressure is 0 to 1.0 MPa, negative pressure reaches -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the temperature range is -20 to +70 C. Applicable tubing is soft nylon or polyurethane. The -S suffix adds a SUS304 stud and the D suffix gives a black body; neither changes any pressure or temperature figure.
No. On the PYB family the -S option only makes the male stud SUS304 for corrosion resistance in wash-down, marine or chemical settings. The body remains PBT, the pressure and temperature ratings are identical to the standard grey part, and the dimensions match the standard catalogue tables, so it is a direct replacement.
