About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB803D
The PEB803D is an AirTAC PEB male branch tee from the resin one-touch family: a Dia 8 mm push-in socket on each end of a straight run, with a 3/8in PT male stud set at 90 degrees on the branch. Push the tube home and the stainless spring gasket plus the chuck grip it under the POM release button; press the button and the tube frees again. The D suffix is the black variant, and on the PEB series it changes the whole body colour, not just the button as it does on PC and POC.
This part runs on the resin spec profile, not the metal BP line: 0 to 1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum capability, 1.5 MPa proof pressure, and -20 to +70 C with soft nylon or polyurethane tubing. The 3/8in stud arrives with sealant already applied to the thread so it seals straight into a PT port without tape. Body is PBT over a brass stud, with an aluminium-alloy guide and NBR O-ring.

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 PEB803D Is Used
CNC fixture clamping branch
Take a 90 degree branch off a Dia 8 supply run to feed a 3/8in-ported clamping manifold on a machining or welding fixture.
Valve island tap-off
Branch a 3/8in PT supply leg from a Dia 8 trunk line into the inlet port of a valve island or air preparation stack.
Lab automation drop
Split an 8mm bench-top supply line to run a small pick-and-place or sample-handling actuator off a 3/8in branch connection.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB803D the Right Part?
On the same 3/8in branch thread, PEB603 (Dia 6) and PEB1003 (Dia 10) are the neighbours below and above this SKU. Dia 6 suits lighter loads and short drops; Dia 10 is the step up for lines feeding bigger cylinders or longer runs where you want less restriction through the bore. Staying with Dia 8 tube but facing a different port thread, the same shape exists as PEB801 (1/8in), PEB802 (1/4in) and PEB804 (1/2in).
A branch tee takes its outlet at 90 degrees off a straight run; if the third leg needs to sit in-line with the run instead, that is the PED male run tee shape. One rule is absolute: tubing OD must match the socket exactly, so a Dia 8 fitting will not hold 1/4in or 5/16in tube regardless of thread.
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 PEB803D FAQ
It is a Dia 8 mm tube male branch tee with a 3/8in PT male stud on the branch. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C with soft nylon or polyurethane tubing.
Match the stud to the port rather than adapting down: PEB803D carries a 3/8in PT thread. For Dia 8 tube on 1/4in ports order PEB802, and the same shape is also stocked in the ladder as PEB801 (1/8in) and PEB804 (1/2in).
