About the Airtac PYB Y-Type Threaded Tee Fitting PYB802
The AirTAC PYB802 is a branch Y threaded one-touch fitting that takes one Dia 8 mm air line in on the threaded leg and splits the flow out to two Dia 8 mm tube legs at a gentle included angle. Where a union tee forces one branch to turn through 90 degrees, the Y keeps both legs angled away from each other, which lets tubing run with wider bends and less kink risk. The 1/4 inch PT male thread screws straight into a valve port, manifold or cylinder port.
Connection is genuinely one-touch: push the soft nylon or PU tube into the collet until it bottoms, and the stainless spring gasket and chuck grip it for a seal that holds both pressure and vacuum. Press the POM release ring to free the tube. This is the resin spec profile, not the metal BPC 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 port arrives pre-coated with sealant, so no extra tape or paste is needed; body is PBT over a brass stud with an NBR O-ring.

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 PYB802 Is Used
Rotary capping head on a bottling line
A single 1/4in valve outlet splits through the PYB802 to two Dia 8 lines feeding the cap-placement and cap-press cylinders, with the Y angle letting both tubes exit the rotating frame without a sharp bend.
Cartoner vacuum-and-blowoff station
One manifold port feeds both the ejector supply and the cardboard flap blow-off nozzle in matched Dia 8 tube, and the NBR seal holds the -750 mmHg vacuum side as reliably as the pressure side.
Semi-automatic palletiser guard interior
Inside a cramped guard where a 90 degree tee would force a tight tube bend, the Y splits supply to the pusher and clamp actuators with a gentler included angle, cutting kink failures on Dia 8 PU tube.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB802 the Right Part?
On the PYB ladder at 1/4 inch thread, Dia 8 sits between two neighbours: step down to PYB602 for a Dia 6 line feeding lighter loads such as small grippers, or step up to PYB1002 for a Dia 10 line feeding larger bore cylinders with correspondingly higher flow. All three exist, so the choice is purely what tube you already run. On the thread side, PYB801 drops to 1/8 inch and PYB803 rises to 3/8 inch, both offered in Dia 8, so match whichever pitch matches your manifold. Remember the interface rule: tube OD must match the fitting exactly, so a Dia 8 Y will not hold 6 mm or 10 mm tube. If you need both outlets at right angles instead of angled, a PED male run tee is the correct shape, not this Y.
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 PYB802 FAQ
The PYB802 joins one Dia 8 mm tube inlet to two Dia 8 mm tube branches on a 1/4 inch PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the operating temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tube and the standard body colour is grey.
It is not required. AirTAC ships every threaded part in this range with sealant already applied to the thread, so the PYB802 can be screwed straight into a port. If a port is worn or you prefer tape, adding a light PTFE wrap is acceptable, but avoid over-applying it where fragments could enter the air path, and never fit this PT-threaded part into a parallel G or NPT port.
