About the Airtac PYB Y-Type Threaded Tee Fitting PYB1004
The PYB1004 is an AirTAC PYB branch Y, a one-touch fitting that divides a single Dia 10 mm supply line into two flow paths from a 1/4 in PT male thread. Push the soft nylon or polyurethane tube into the port and the internal chuck grips its outer surface; press the POM release ring and the tube frees again for rework or re-routing.
It belongs to the resin and brass one-touch family, so it is rated 0 to 1.0 MPa working pressure, tolerates -750 mmHg vacuum, carries a 1.5 MPa proof pressure and works from -20 to +70 C. The outer housing is PBT with a brass stud, the thread arrives pre-coated with sealant, and the standard body colour is grey.

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 PYB1004 Is Used
Splitting a paint-line valve feed
One 1/4 in PT drop from the supply rail can serve two Dia 10 mm legs, each running to its own spray-gun actuation valve without a second threaded take-off.
Twin-acting clamp on a CNC fixture
A single regulated line feeding both sides of a pneumatic clamp circuit can be Y-split at the manifold stud, keeping the fixture plumbing symmetrical.
Dual-blow nozzles on a bottling table
The 1/4 in thread mounts directly to a filter-regulator outlet while the two Dia 10 mm legs feed paired air-nozzle jets that clear containers from a conveyor.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1004 the Right Part?
Dia 10 mm sits in the middle of the PYB ladder. Step down to PYB802 for Dia 8 mm tube on the same 1/4 in thread when the branch is feeding a smaller valve or actuator, or step up to PYB1204 for Dia 12 mm when the trunk line carries the full output of a larger FRL unit. Moving between them changes the bore, and with it the air speed and capacity through the split - the thread stays the same.
Check the receiving port before ordering: this stud is 1/4 in PT and seals through the applied thread sealant. If the trunk line itself branches without reaching a threaded port, a tube-to-tube PY union Y is the shape to compare instead. Tubing OD must match exactly - a Dia 10 mm port will not seal on 3/8 in hose.
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 PYB1004 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum capability -750 mmHg, proof pressure 1.5 MPa, temperature range -20 to +70 C. The tube ports accept Dia 10 mm soft nylon or polyurethane tubing and the male stud is 1/4 in PT. The body is PBT on a brass stud with a POM release ring, and grey is the standard colour.
Yes - on the PYB range the two legs and the trunk all accept the same tubing OD, so the PYB1004 grips Dia 10 mm tube in all three ports. If you need to step the branch legs down to a smaller bore, that is a job for the PG different-diameter straight or PYW different-diameter union Y downstream, not this fitting.
