About the Airtac PYB Y-Type Threaded Tee Fitting PYB1202-S
The PYB1202-S is an AirTAC union Y branch in the resin one-touch family, splitting a single Dia 12 mm tube line into two 12 mm outlet legs at an angle, with a 1/4 in PT male thread on the branch port. Push each tube home and the internal chuck grips it along its full circumference; pressing the POM release ring frees the tube again without tools. The threaded port arrives with sealant already applied, so it goes straight onto a PT tapped hole.
Because this SKU carries the -S suffix, the load-bearing stud is SUS304 stainless steel while the body stays PBT and the chuck, release button and guide keep their standard construction (POM, aluminium-alloy guide, stainless spring gasket, NBR O-ring). Ratings are identical to the grey version: 0-1.0 MPa working, 1.5 MPa proof, vacuum to -750 mmHg, and -20 to +70 C. If your spec sheet calls out a solid stainless body, the PC and POC straight connectors are the parts that offer that, not this Y.

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 PYB1202-S Is Used
Carton-closing clamp branch
On a case-packing line, one 1/4 in port off the machine's valve manifold feeds the Y, which then supplies both cylinders of a top-and-bottom carton clamp from a single connection.
Acidic wash cabinet at a plating shop
Where the panel behind the fitting sees intermittent acid mist, the SUS304 stud resists corrosion at the thread interface, and the whole fitting releases for fast hose changes between bath changeovers.
Twin air nozzles on a bottling line rail
A single 12 mm drop line down the conveyour guard splits through the Y to feed two blow-off nozzles that clear residual rinse water from bottle necks before labelling.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1202-S the Right Part?
On the 1/4 in thread this Dia 12 bore is the top of the PYB ladder - the only smaller tube on this thread is Dia 10 (PYB1002), which drops the bore for lighter-flow branches. If you need to keep Dia 12 tube but the port is larger, the same tube size exists on PYB1203 (3/8 in) and PYB1204 (1/2 in). Match the tube exactly: Dia 12 is not interchangeable with 1/2 in (12.7 mm) tubing, and an undersized tube will not seal in the chuck.
Choose a Y over a PED run tee when you want two lines leaving one entry without the bulk of a cross-body; choose a PY union if both outlets must be tube-to-tube with no threaded port at all.
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 PYB1202-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The tube connection is Dia 12 mm OD on all three legs and the threaded port is 1/4 in PT. The -S suffix adds a SUS304 stud; all pressure and temperature figures are unchanged from the standard PYB1202.
No. The chuck is cut for 12.0 mm OD soft nylon or polyurethane tube. A nominal 1/2 in tube measures about 12.7 mm OD and will not seat in the grip, while anything smaller will not seal. Use genuine 12 mm OD tube, or move to the PYB1002 on this thread if your circuit runs on Dia 10 mm tube.
