About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB401D
The PEB401D is an AirTAC PEB male branch tee from the resin one-touch range. It carries two Dia 4 mm tube sockets in line and a 1/8 inch PT male thread on a right-angle branch, so a single supply port can feed two tube circuits from one point. Making the joint takes seconds: push the tube straight in until it bottoms, an internal chuck grips the OD and a stainless spring gasket seats the seal, and pressing the POM release ring frees the tube again without tools.
This is the resin-and-brass spec profile: 0-1.0 MPa (0-10 kgf/cm2) working pressure, 1.5 MPa proof, -750 mmHg (10 Torr) vacuum and -20 to +70 C, with soft nylon or polyurethane tubing. The D suffix gives a black body on this series - unlike PC and POC, where black changes only the release button. The PBT housing carries a brass male stud that arrives with thread sealant pre-applied.

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 PEB401D Is Used
Vacuum ejector pick-up circuit
The PEB401D holds -750 mmHg (10 Torr), so a Dia 4 branch tee can split the line at a compact ejector on a semiconductor pick-and-place head, feeding both the suction cup and a vacuum switch from the 1/8 inch PT port.
Cartoning machine air-signal tee
On a food cartoning line, the branch takes a Dia 4 signal off the solenoid outlet to a small gripper cylinder while the straight run continues to a pressure switch - one push-in joint instead of two threaded unions in a tight guard.
Rotary index table plumbing
Winding the pre-sealed 1/8 inch stud into the fixture port on an indexing dial, with two Dia 4 nylon lines running to the clamps, keeps the rotary union area clear and lets either clamp be dropped by pressing one release ring.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB401D the Right Part?
On the PEB 1/8 inch ladder the tube sizes are Dia 4, 6, 8 and 10 mm, so Dia 4 is the smallest bore this thread is offered with; the next step up is PEB601 with a Dia 6 bore, which suits slightly larger air or signal lines. If the port rather than the tube is what varies, the same Dia 4 tube also exists on PEB M5 and 1/4 inch bodies. Match the thread to the port first, then the tube: a Dia 4 socket will not grip 6 mm or 1/4 inch tubing, and forcing a mismatch weeps air. Where three tube ends are needed and no thread, a PE union tee is the shape to look at instead.
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 PEB401D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature range -20 to +70 C. The fitting takes Dia 4 mm soft nylon or polyurethane tubing and carries a 1/8 inch PT male thread on the branch.
No. AirTAC ships PEB threaded bodies with sealant already applied to the brass male stud, so the PEB401D can be wound straight into the PT port. Only if you later relocate the fitting into a different port should you re-apply PTFE tape or pipe sealant first.
