About the Airtac PYB Y-Type Threaded Tee Fitting PYB1202D-S
The PYB1202D-S is an AirTAC branch Y in the stainless -S variant: it splits a single Dia 12 mm supply line into two branches at a fixed Y angle, off a 1/4in PT male thread. Push the tube home and the internal chuck grips it; press the POM release ring and it frees again, so branches can be re-routed without tools. The D suffix makes this the black-bodied version, not a performance change.
This is the resin spec profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C. In -S form the body stays PBT engineering polymer and the threaded stud is SUS304 - so the corrosion-exposed face at the port is stainless while the fittings stays light and chemical-tolerant. AirTAC threads arrive pre-coated with sealant, ready to wind straight into the 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 PYB1202D-S Is Used
Plating line rinse station
A 1/4in ported air feed at a rinsing tank split to two spray nozzles, where splash and fume attack bare brass studs and the SUS304 thread resists it.
Fish-farm aeration ring
Feeding two Diffuser runs from one Dia 12 trunk line on a saltwater-site air ring, using the Y to balance flow without an extra tee and elbow.
Chemical dosing skid purge
A purge-air branch on a dosing skid where the black body keeps the routing visible against dark pipework and the stainless stud shrugs off acid vapour.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1202D-S the Right Part?
Dia 12 is the top of the PYB 1/4in ladder - the only neighbour below it is Dia 10 (PYB1002D-S), which suits lighter branch loads and smaller actuators; there is no 16 mm step up in this catalogue. If the port itself is the mismatch, the same Dia 12 body exists on a 3/8in thread (PYB1203) and a 1/2in thread (PYB1204). Match the stud to the port thread, not the other way round.
Two cautions: tube OD must match exactly, so a Dia 12 Y will not grip 1/2in imperial hose no matter how close it looks; and if you need a pass-through a panel rather than a split, the bulkhead PM series is the right shape 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 PYB1202D-S FAQ
It is a branch Y one-touch fitting for Dia 12 mm tubing with a 1/4in PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Use soft nylon or polyurethane tube with a true 12 mm OD. These ratings are identical to the non-stainless PYB1202D - the -S changes the stud material, not the numbers.
The threaded stud becomes SUS304 stainless steel for corrosion resistance at the port. The body remains PBT polymer and the release button stays POM, so this is not a solid stainless part and it is not re-rated in any way. AirTAC publishes no corrosion class, salt-spray hours or food certification for it, and the dimensions match the standard grey PYB1202 exactly.
