About the Airtac PYB Y-Type Threaded Tee Fitting PYB801D
The PYB801D is an AirTAC PYB branch Y, a threaded one-touch fitting that takes a single 1/8 in PT male port and splits it into two Dia 8 mm tube outlets set at a Y angle. Push each tube home and the internal chuck grips it; press the release ring and the tube slides straight back out. On this series the trailing D means the whole body is moulded in black rather than the standard grey, which matters on machines where grey hardware disappears against dark frames and techs need to spot an air point fast.
This is the resin one-touch family, not the metal line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The POM release button and chuck sit over a PBT threaded body on a brass stud, and the 1/8 in PT taper arrives with sealant already applied, so the port seals on first assembly without extra tape.

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 PYB801D Is Used
Splitting one solenoid output to twin grippers
A pick-and-place head on a small cartesian robot needs two parallel grippers acting together. One 1/8 in PT valve port feeds the PYB801D, and the Y branches the signal evenly into two 8 mm lines, saving a second fitting on the manifold.
Packaging line air nozzles from a shared feed
On a carton sealer, two blow-off nozzles clear dust from opposite sides of the belt. A PYB801D mounted at the frame's air outlet splits the 1/8 in PT supply into a pair of 8 mm runs, one to each nozzle, with push-in reconnection when nozzles are swapped.
Lab autoclave and wash rig branch plumbing
A laboratory wash rig routes clean dry air from one regulator to two small actuators inside a tight stainless enclosure. The black PYB801D stays visible against dark pipework, and the -20 to +70 C resin rating covers the ambient range at the air side of the machine.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB801D the Right Part?
On the 1/8 in thread ladder, PYB steps through Dia 4, 6, 8 and 10. Step down to PYB601 for a 6 mm branch feeding lighter loads such as single-acting cylinders or air jets; step up to PYB1001 when the two branches carry a bigger draw and 10 mm tubing keeps velocity and pressure drop down. If the port itself is a 1/4 in PT, the neighbouring SKU is PYB802 - same 8 mm bore, one thread size up.
The tube bore must match exactly: a Dia 8 fitting will not seal on 1/4 in (6.35 mm) or 5/16 in hose. If the split needs to pass through a panel wall instead of sitting on a manifold, the PM bulkhead connector is the shape for that job; if the two branches need to swivel onto angled ports, look at the PH universal elbow range instead. Use soft nylon or polyurethane tubing only - harder pipe materials will not seat in the chuck.
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 PYB801D FAQ
It is an AirTAC PYB branch Y with a Dia 8 mm tube connection on both legs and a 1/8 in PT male thread (PT is the standard across this whole catalogue). 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. Applicable tubing is soft nylon or polyurethane, and the D suffix gives a black body rather than the standard grey.
No extra tape or paste is needed: AirTAC pre-applies thread sealant to the tapered PT stud, so it seals straight into the port on first assembly. Just make sure the port itself is clean and undamaged. Also note the two Y outlets only accept genuine Dia 8 mm soft nylon or polyurethane tube - forcing 1/4 in (6.35 mm) hose into the chuck will not seal and will leak under pressure.
