About the Airtac PYB Y-Type Threaded Tee Fitting PYB1003
The AirTAC PYB1003 is a male-threaded branch Y in the resin one-touch family: a 3/8in PT male thread feeds two Dia 10 mm push-in outlets arranged in a Y, so a single valve port can split into two tube runs without a separate tee and nipple. It is part of the grey resin and brass range with a PBT threaded body and brass stud.
Each outlet works like any one-touch fitting: push the soft nylon or polyurethane tube in until it bottoms, and the internal chuck grips it against the stainless spring gasket; press the release ring and the tube slides out again. Ratings are the resin profile - 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C. AirTAC applies sealant to the male thread before packing, so the 3/8in PT port seals straight into a tapped manifold or valve body 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 PYB1003 Is Used
Twin suction cups on a pick-and-place arm
Split the single 3/8in output of a vacuum or air valve into two Dia 10 lines feeding paired suction cups, keeping the gripper plumbing to one fitting instead of a tee plus two nipples.
Small pneumatic press with dual feed lines
Take one supply branch off a manifold port and divide it to the two Dia 10 lines serving a compact air press or clamp cylinder set on a packaging line.
Manifold branch to two actuators
Where a control cabinet-adjacent manifold has one spare 3/8in tapped port, use the Y to run two Dia 10 polyurethane lines out to separate small actuators without extra threaded joints.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1003 the Right Part?
On the 3/8in rung of the PYB ladder the neighbouring sizes are PYB0803 (Dia 8 tube) below and PYB1203 (Dia 12 tube) above. Stepping down to 8 mm trims the bore for lighter-flow circuits and shorter runs; stepping up to 12 mm suits longer branches or actuators that draw more air. Note that Dia 10 sits mid-ladder: the small M5 PYB versions only carry 4 and 6 mm tube, so a 10 mm branch Y always needs a 1/8in to 1/2in thread. If the branch point sits inside a machine frame where a rigid Y cannot swing into place, a PH-style universal elbow with swivelling thread may fit better. Match tube OD exactly - a Dia 10 outlet will not seal on 3/8in imperial tube, and a 3/8in thread will not seat in a 1/4in tapped port without a reducer.
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 PYB1003 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting is a Dia 10 mm tube branch Y with a 3/8in PT male thread, from the resin one-touch range with PBT body and brass stud. Applicable tubing is soft nylon or polyurethane.
On the 10 mm branch Y the published thread ladder is 1/8in (code 01), 1/4in (02), 3/8in (03) and 1/2in (04) - there is no M5 version at this tube size, since M5 PYB fittings only support Dia 4 and Dia 6 tube. If your port is a 1/4in tapped hole, order PYB1002 rather than adapting this 3/8in part.
