About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB402
The PEB402 is an AirTAC PEB male branch tee, a three-way push-in fitting that takes a Dia 4 mm tube into each of its two tube ports and presents a 1/4in PT male thread as the third leg. What makes a branch tee different from a run tee is the geometry: on the PEB the male thread sits at the branch, set at 90 degrees off the straight tube run, so the tee drops a side take-off from a main air line without bending the run itself.
To make the connection, push the Dia 4 mm tube straight home into a port - the stainless spring gasket and chuck grip it immediately against a PBT body with a brass male stud. Press the release ring to free the tube. This is the resin one-touch profile: 0-1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and a -20 to +70 C operating window. AirTAC ships the male thread with sealant already applied, so the 1/4in leg seals into the port with no extra tape in most cases.

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 PEB402 Is Used
Pick-and-place gripper feed
On an electronics assembly head, the PEB402 taps a Dia 4 mm branch off the main supply run to feed a compact pneumatic gripper, leaving the primary line untouched for the next station.
Benchtop dispensing rig
A laboratory dispensing or fluid-handling bench uses the 1/4in male leg to anchor the tee at a regulator or manifold port while two short Dia 4 mm tubes run out to twin micro-cylinders.
Carton-erector vacuum leg
On a packaging machine's carton-erector, the branch tee splits the Dia 4 mm line feeding a small vacuum ejector, so flap pickup and cylinder return share one supply without a separate junction block.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB402 the Right Part?
At the 1/4in thread, Dia 4 mm is the smallest tube size AirTAC makes on the PEB ladder - there is nothing below it. Step up one size to Dia 6 (PEB602) when the branch feeds a slightly larger cylinder or needs a bit more effective bore for longer runs; Dia 8, 10 and 12 follow on the same 1/4in thread. On the thread side, this same Dia 4 tube is also available with a 1/8in male (PEB401) or an M5 male for the smallest ports, so check the receiving thread before committing to the 402. Keep the tube OD exact: this port seats Dia 4 mm soft nylon or polyurethane only - a nominal 1/4in (6.35 mm) tube will not grip and will leak or blow out under pressure.
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 PEB402 FAQ
It joins Dia 4 mm soft nylon or polyurethane tube on two legs to a 1/4in PT male thread on the branch leg. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The body is PBT with a brass stud, and the standard finish is grey; the D suffix changes the body to black.
No. The chuck and gasket in this fitting are dimensioned for exactly Dia 4 mm metric tube. A nominal 1/4in (6.35 mm) tube is over half a millimetre larger and will not seal correctly. Either change the tube to true Dia 4 mm, or move up the ladder to the Dia 6 model (PEB602) if your circuit can accept the larger bore.
