About the Airtac PYB Y-Type Threaded Tee Fitting PYB803
The PYB803 is an AirTAC PYB branch Y one-touch fitting: a male 3/8in PT threaded inlet that splits into two angled push-in outlets, each taking Dia 8mm soft nylon or polyurethane tubing. Unlike a PE union tee, the Y shape angles the two branches away from each other, which relieves side load on the tube and lets two lines leave the same port without crossing. Push each tube home until it seats and the stainless spring gasket and chuck grip it; press the release ring to free it. The 3/8in PT thread arrives with sealant already applied, so it seals straight into the port.
This PYB belongs to the resin and brass one-touch line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The threaded stud is brass with a PBT body, POM chuck and release button, aluminium-alloy guide and NBR O-ring. Both outlets are Dia 8 - the code carries a single tube size, so this is not a reducer.

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 PYB803 Is Used
Twin blow-off nozzles on a packaging drying station
One 3/8in valve port splits into two angled Dia 8 drops aimed at wet labels or inkjet codes on a carton line, keeping both nozzle hoses clear of the conveyor frame.
Dual swing clamps on a welding fixture
A single 3/8in supply branch feeds two Dia 8 clamp cylinders mounted either side of a jig, with the Y angle matching how the clamps face each other across the part.
Two suction cups on a sheet-picking end effector
On a gantry picking sheet metal or board, one 3/8in vacuum-side connection serves two Dia 8 cup lines while the angled Y keeps both hoses off the payload.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB803 the Right Part?
On the 3/8in thread, the PYB ladder runs Dia 6, 8, 10 and 12, so PYB803 sits between PYB603 below and PYB1003 above. Stepping down to 6mm suits lighter actuator circuits and smaller fittings at the port; stepping up to 10mm lowers restriction when the two branches feed longer runs or higher-flow consumers. The same Dia 8 Y is also offered on 1/4in (PYB802) and 1/2in (PYB804) threads if your port differs. Always match the fitting tube size to the tubing OD exactly - a Dia 8 chuck will not seal on 5/16in or 10mm tube, and the joint will leak or blow off under pressure.
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 PYB803 FAQ
It is a PYB branch Y one-touch fitting with Dia 8mm push-in outlets and a 3/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum capability -750 mmHg (10 Torr), proof pressure 1.5 MPa, and the operating temperature range is -20 to +70 C. It takes soft nylon or polyurethane tubing; the standard body colour is grey.
Yes. The PYB code carries one tube diameter only, so both branches of the PYB803 accept exactly Dia 8mm tube. If you need the branches to step down to a smaller actuator line, use a PKG or PHK reducer union after the Y rather than forcing mismatched tube into the chuck - the grip is sized for one OD and will not seal on anything else.
