About the Airtac PYB Y-Type Threaded Tee Fitting PYB603
The AirTAC PYB603 is a one-touch branch Y, AirTAC's own name for this shape: a male threaded stem in 3/8in PT that splits into two push-in ports, both sized for 6 mm outside diameter soft nylon or polyurethane tube. Push each tube home and the internal chuck grips it; press the POM release ring and the tube frees off again, so branching an air line needs no tees, no nipples and no spanner work on the tube side.
This is the resin one-touch profile, not the metal BPC line: working pressure 0-1.0 MPa, vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. The 3/8in male stem arrives with sealant already applied to the PT thread, and the sealing stack inside each port is a stainless spring gasket over an NBR O-ring, with a brass stud carrying the thread.

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 PYB603 Is Used
Splitting rinse-air feed on a bottling line
A 3/8in manifold port branches into two 6 mm lines feeding air blast nozzles either side of a bottle neck, with both legs released and re-routed by button when nozzle spacing changes.
Dual vacuum cup feed on a pick-and-place gantry
One vacuum source port in 3/8in PT splits to two 6 mm cup lines on a carton picker, keeping both cups on a common vacuum drop sized for the larger stem bore.
Branching sensor cooling air in a plastics press shop
A 6 mm cooling-air wipe across a mould proximity sensor and its cable gland both fed from a single 3/8in blow-off port, avoiding a loose tee joint inside the guard.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB603 the Right Part?
Dia 6 is the smallest tube that exists on PYB at 3/8in - there is no Dia 4 PYB603, because AirTAC's interface table starts the 3/8in row at Dia 6. Step up to PYB803 for an 8 mm bore on the same thread when the branch feeds something hungrier than a 6 mm line, and note that the two legs of the Y are always the same diameter: a Y cannot split one bore into two different sizes. Below this SKU, PYB602 on 1/4in carries the same Dia 6 tube, and the 1/2in row only opens up at Dia 8, so there is no PYB604 - do not order one.
Match the 3/8in stem to the port, not to the tube: the stem seals on its PT thread, the tube seals in the chuck, and the two choices are independent. If the branch has to pass through a panel or plate instead, the PM bulkhead union or PLM bulkhead male elbow is the shape you want, and PH covers swivelling-angle needs. Always match tube OD exactly - a Dia 6 port will not hold 1/4in (6.35 mm) tube even though the difference looks negligible on a ruler.
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 PYB603 FAQ
It is a one-touch branch Y joining 6 mm OD soft nylon or polyurethane tube to a 3/8in PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Body materials are POM, PBT and aluminium alloy with a brass stud, NBR O-ring seals, and the PT thread arrives with sealant applied.
No. Both legs of a PYB branch Y are machined for one tube diameter only, here Dia 6 mm, and AirTAC does not make a mixed-bore Y. If the branch must step down, put a PG different-diameter straight union on one leg, or use the PKD male reducer triple branch family which combines the thread port with a smaller branch bore in a single part.
