About the Airtac PYB Y-Type Threaded Tee Fitting PYB1203-S
The AirTAC PYB1203-S is a one-touch branch Y fitting that turns one 3/8in PT male thread into two Dia 12 mm push-in tube outlets angled apart from the same port. Push each tube home and the internal chuck grips it; press the release ring to free it again. Because the branch splits the flow at the port itself, you get two lines without adding a separate tee and its extra joints.
This is the SUS304 stud variant of the resin Y series: the stud that screws into your port is stainless steel 304, while the fitting body stays PBT and the chuck, guide, spring gasket and NBR O-rings follow the standard build. Ratings are unchanged by the -S suffix: 0 to 1.0 MPa working pressure, 1.5 MPa proof, -20 to +70 C, and -750 mmHg vacuum. The 3/8in thread arrives with sealant already applied, so it seals straight into a PT port.

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 PYB1203-S Is Used
Twin vacuum cups on a pick-and-place gantry
A single 3/8in port on the gantry manifold feeds the Y, which branches into two 12 mm lines running to the left and right suction cups, keeping cup lines equal in length.
Paired air nozzles on a bottle-rinse line
One threaded take-off on the wash-side header serves two blow-off nozzles facing the bottle shoulders; the Y branch halves the joint count compared with a tee plus two elbows.
Split feed on a carton-sealing machine
The Y branches one supply into a 12 mm cylinder line and a second 12 mm line for the flap-hold-down actuator, both released by the same push-to-connect method during changeover.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1203-S the Right Part?
Dia 12 on a 3/8in thread is the top of the PYB ladder for this thread size - 3/8in stops at Dia 12, so there is no larger tube to step up to here. If you step down, PYB1003-S gives you Dia 10 on the same thread with a smaller bore and slightly lower flow path; if you need Dia 12 but want a coarser, deeper-engaging thread, PYB1204-S puts the same tube on a 1/2in PT stud. Whichever way you go, the tube OD must match the fitting exactly - a Dia 12 chuck will not seal on 1/2in tubing even though the numbers sound close.
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 PYB1203-S FAQ
Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure is 1.5 MPa, vacuum capability is -750 mmHg (10 Torr), and the temperature range is -20 to +70 C. The fitting accepts Dia 12 mm soft nylon or polyurethane tube on both outlets and has a 3/8in PT male thread. These figures are identical to the standard PYB1203; the -S suffix changes only the stud material to stainless steel 304.
No. On the branch and tee families the SUS304 upgrade applies to the male stud only; the body remains PBT with a POM chuck, aluminium-alloy guide and NBR seals. Only the straight PC and POC connectors get a solid stainless body. The pressure, vacuum and temperature ratings are not re-rated for the -S version, so treat it as the standard fitting with a corrosion-resistant stud.
