About the Airtac PYW Y-Type Reducing Tee Fitting PYW10-8
The PYW10-8 is AirTAC's different diameter union Y: a three-leg one-touch fitting that joins a Dia 10 mm tube to two Dia 8 mm tube legs without any threaded port in the middle. Push each tube straight into its socket until it bottoms out; the internal chuck grips the tube wall and the stainless spring gasket seals around the outside of the OD. Pressing the release ring unlocks the chuck so the tube pulls back out, and each leg can be released and re-terminated independently.
This part belongs to the resin and brass one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service window of -20 to +70 C. The body is grey PBT with POM chucks and an NBR seal, and it is rated for soft nylon or polyurethane tube only. Because it is a union, the whole fitting carries no pipe thread - the connection is tube-to-tube from end to end.

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 PYW Y-Type Reducing Tee Fitting PYW10-8 Is Used
Packaging line vacuum and blow-off split
On a carton-sealing conveyor, a 10 mm trunk from the air preparation unit can be divided into two 8 mm legs feeding a suction cup line and a blow-off nozzle, using one Y instead of a tee plus a reducer.
CNC coolant-free air curtain on a machining centre
A Dia 10 feed from the machine's air drop can be Y-split into two 8 mm nozzles aimed at the spindle taper and the chip area, clearing swarf without touching the coolant circuit.
Laboratory automation pneumatic dividers
On a sample-handling bench where space is tight, a 10 mm supply line can branch into two 8 mm actuator feeds for a gripper and a pusher cylinder, all pushed together by hand with no tools or thread sealant.
Is the Airtac PYW Y-Type Reducing Tee Fitting PYW10-8 the Right Part?
In the PYW reducing ladder this Dia 10 x Dia 8 sits between PYW8-6 and PYW12-10. Step down to PYW8-6 when the trunk line is a 6 or 8 mm feed, for example a compact valve manifold outlet; step up to PYW12-10 when a 10 or 12 mm trunk is feeding heavier actuators. The larger leg should land on the supply side and the two smaller legs on the branches, so pressure drop happens downstream where the flow is smaller.
Measure the tube wall, not just the OD, before ordering: these sockets are cut for soft nylon and polyurethane and hold only an exact OD match, so a Dia 8 leg will not seal on 5/16 inch or 8.5 mm tube. If you actually need a threaded branch instead of a plain union, the PED male run tee or PYB branch Y is the shape to compare against.
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 PYW Y-Type Reducing Tee Fitting PYW10-8 FAQ
It is a different diameter one-touch union Y joining Dia 10 mm tube to two Dia 8 mm tube legs, with no pipe thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. It is the resin and brass profile, rated for soft nylon or polyurethane tube.
Fit the Dia 10 leg to the larger supply line and the two Dia 8 legs to the smaller branches; that keeps air velocity sensible at the split. The sockets are not interchangeable between sizes - each one grips only its own exact OD - but any leg can be released by pressing the release ring and re-fitted with fresh tube cut square, with no thread sealant to renew because there is no thread.
