About the Airtac PE Tee Connector PE8D
The PE8D is an AirTAC PE union tee in the resin one-touch range, finished in black (the D suffix). It joins three lengths of Dia 8 mm soft nylon or polyurethane tube at a 90-degree junction with no thread anywhere in the part, so the whole branch line is tube-to-tube. Push each tube firmly into its port and the internal chuck grips it; press the release ring to free it again.
Because this is the resin profile, the ratings are 0-1.0 MPa (0-10 kgf/cm2) working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. On the PE series the D suffix changes the colour of the entire body, not just the release button as it does on a PC straight connector, so the fitting reads black on the machine. Inside, a POM chuck, aluminium guide, stainless spring gasket and NBR O-ring hold the seal on each leg.

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 PE Tee Connector PE8D Is Used
Pick-and-place branch to an ejector
Tee the Dia 8 supply run on a pick-and-place robot head to feed both the vacuum ejector and the panel purge jet from one drop, keeping the branch inside the arm shroud.
Twin air knives on a filling line
Split a single Dia 8 drop into two equal legs feeding rinse-blow air knives on a bottling conveyor, with the tee mounted in the tube run clear of wash spray.
Press fixture supply and blow-off
At a small pneumatic press, branch the Dia 8 clamp-cylinder feed off the main supply and carry a leg onward to the part-blow-off nozzle at the die.
Is the Airtac PE Tee Connector PE8D the Right Part?
The PE ladder steps PE6-PE12. Drop to a Dia 6 union tee when you are branching from a thin actuator pilot line; step up to Dia 10 when the branch feeds a larger bore cylinder where pressure drop in the tee would be felt on the exhaust stroke. This Dia 8 size sits in the middle and is the common choice for main machine supply legs. Note that tube OD must match exactly - an 8 mm port will not reliably hold 1/4 in (6.35 mm) tube.
Since there is no thread, there is no port to match and nothing to apply sealant to; pick this shape over a threaded PEB male branch tee when the tee itself lives in the tube run rather than screwed into a manifold. If you need the grey version instead, order PE8.
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 PE Tee Connector PE8D FAQ
It is a Dia 8 mm tube-to-tube union tee on the resin one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C, for soft nylon or polyurethane tube.
No. It is the black-colour variant. On the PE union tee the D suffix colours the whole body black, whereas on the PC straight connector it changes only the release button, so do not assume the two prefixes behave the same. Performance, dimensions and port sizes are identical to the grey PE8.
