About the Airtac PYB Y-Type Threaded Tee Fitting PYB1003D
The PYB1003D is an AirTAC PYB branch Y, a one-touch fitting that turns a single 3/8in PT male thread into two Dia 10 mm tube outlets set at a Y angle. Push each tube into its socket and the internal stainless chuck grips the OD; press the POM release ring and the tube frees again for rework. The male thread arrives with sealant already applied, so it seals straight into a PT port without extra tape.
This is the resin and brass one-touch profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C, for soft nylon or PU tubing. Because the code ends in D, the body itself is moulded in black rather than the standard grey - on the PYB series the D suffix changes the whole body, not just the button.

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 PYB1003D Is Used
Splitting a manifold drop to twin grippers
On a palletising cell, one 3/8in PT manifold outlet can feed two Dia 10 lines at a Y angle, supplying a pair of pneumatic grippers from a single port without adding a tee block.
Valve manifold common supply branch
Where a control cabinet valve manifold has one spare 3/8in port, the PYB1003D branches it into two Dia 10 feeds for double-acting cylinders mounted on either side of a machine frame.
Vacuum sharing on pick-and-place heads
Rated to -750 mmHg, the Y lets one vacuum source port serve two Dia 10 suction cups on a carton erecting head, halving the plumbing compared with two separate drop lines.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1003D the Right Part?
On the 3/8in PT thread the PYB ladder runs Dia 6, 8, 10 and 12. Step down to PYB803 when the two branch lines feed smaller actuators, or up to PYB1203 for heavier cylinder supply; only the bore and the gripping chuck change, the thread stays the same. If your port is 1/4in, PYB1002 gives the same Dia 10 Y with a 1/4in male thread instead.
The Y shape matters when two lines must leave a port at an angle rather than the 90 degree split of a PEB branch tee - it keeps twin hoses from crossing over each other. Whatever you choose, tube OD must match exactly: a Dia 10 socket will not grip 3/8in or 12 mm tube reliably.
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 PYB1003D FAQ
It is an AirTAC PYB branch Y joining Dia 10 mm tube to a 3/8in PT male thread, in a black body. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and temperature -20 to +70 C. Tubing must be soft nylon or polyurethane.
No. Each socket grips exactly one tube OD, so both sides of the PYB1003D take Dia 10 mm only. For a 12 mm line on the same 3/8in thread, order the PYB1203, or use a PG different-diameter union to step the bore down if the mixed sizes are deliberate.
