About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1203
The PEB1203 is an AirTAC PEB male branch tee, the shape that splits a tube run while keeping it straight. Two Dia 12 mm push-in ports form the through line, and the 3/8in PT male thread is the 90 degree branch off the side, so the main flow path never has to turn to feed a spur circuit.
It belongs to the resin one-touch family: working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C with soft nylon or polyurethane tubing. Push the tube home and the stainless spring gasket chuck grips it; press the POM release ring and it frees. The 3/8in thread arrives from AirTAC with sealant already applied, so it can normally thread straight into the port.

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 PEB T-Shaped Straight Thread Tee Connector PEB1203 Is Used
Manifold branch on a filling line
On a bottling plant distribution block, thread the 3/8in branch into a spare manifold port and tee Dia 12 tubing sideways to a filter-regulator set, while the main 12 mm run continues straight to the next station.
Clamp cylinder spur feed
At a pneumatic clamping station on a stamping fixture, run the Dia 12 supply line straight through the tee and use the 3/8in branch to feed a pressure switch port, so the clamp circuit keeps full bore to the cylinder.
Sorting conveyor divertor air
Split the Dia 12 header at a divertor module on a parcel sorting conveyor: the through line feeds the next divertor, and the male branch drops air down to the local solenoid valve manifold.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1203 the Right Part?
On the 3/8in thread row of the PEB ladder, Dia 12 is the largest tube size AirTAC makes, so there is no step up from this part. The single neighbour below is Dia 10, ordered as PEB1003, which gives you a slimmer tee body where a 12 mm line is more capacity than the branch needs. The other direction to move is thread: the same Dia 12 tube is also stocked in 1/4in as PEB1202 and in 1/2in as PEB1204, so match the port on the machine rather than resizing the tube.
Tube OD must match exactly. A Dia 12 chuck will not seal on 1/2in nominal hose, and forcing a near-size tube in is the usual cause of slow leaks at the grip teeth. If you need a reducer instead, that is a job for the PKD or PG series, not the PEB.
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 PEB T-Shaped Straight Thread Tee Connector PEB1203 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. This SKU takes Dia 12 mm soft nylon or polyurethane tube in both push-in ports and has a 3/8in PT male branch thread. The release button and chuck are POM, the O-ring is NBR, and the body is PBT over a brass stud.
No. AirTAC ships threaded one-touch fittings in this range with sealant already on the PT male thread, so the PEB1203 can normally be screwed straight into the port. Only M5 sizes in the same catalogue use a sealing gasket instead. If a port is worn and weeps, a wrap of tape is the usual field fix, but check the port threads first.
