About the Airtac PE Tee Connector PE12D
The PE12D is an AirTAC PE union tee, a threadless three-way coupler that branches one Dia 12 mm supply line into two, or merges two return lines into one. All three legs accept 12 mm OD soft nylon or polyurethane tube: push each tube into its port, the internal POM chuck and stainless spring gasket grip it against the NBR O-ring, and press the release ring to let it go. Because there is no thread, nothing needs sealing - the fitting is installed by hand, tube in each port.
This is the resin/brass one-touch profile, not the metal line: 0 to 1.0 MPa working pressure (0-10 kgf/cm2), -750 mmHg vacuum (10 Torr), 1.5 MPa proof pressure and -20 to +70 C. The D suffix on PE parts changes the whole body to black, not just the release button, so it matches black tubing runs on machines where grey hardware would stand out.

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 PE12D Is Used
Bottling line pick-and-place
Splits the 12 mm main feed from a vacuum generator into two actuator drops on a bottle-gripping head, keeping one continuous line with no threaded joints to loosen.
Conveyor gripper rail branch
Takes the 12 mm supply running along a pallet conveyor and feeds both sides of a pneumatic clamping rail from a single tee, in black to match black tubing routing.
Trailer air accessory split
Branches a 12 mm nylon line feeding cab-mounted actuator accessories into two circuits on commercial-vehicle test rigs, where vibration makes push-fit unions preferable to threaded tees.
Is the Airtac PE Tee Connector PE12D the Right Part?
PE12D sits at the top of the ladder. The only sibling below it is PE10 for 10 mm tube, where flow through the narrower bore drops and the fitting body shrinks; there is no larger PE in this catalogue, so if your line is bigger than 12 mm you need a different series. Dia 12 is the maximum tube size AirTAC publishes for this resin family.
Check your tubing with a calliper before ordering: the ports are cut for exactly 12.0 mm OD, so nominal 1/2 inch hose at 12.7 mm will neither seat nor seal. If you need to step down to a 10 or 8 mm branch instead of a same-size tee, use a PEG or PEW different-diameter tee; if you need a threaded take-off from the run, a PED male run tee is the threaded equivalent.
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 PE12D FAQ
PE12D is an AirTAC PE union tee for three 12 mm OD tubes with no thread. Working pressure 0 to 1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It takes soft nylon or polyurethane tubing and has a black PBT body (D suffix). No flow coefficient is published; capacity follows the characteristic curve for a 12 mm bore.
No. The ports grip exactly 12.0 mm OD tube; nominal 1/2 inch hose measures about 12.7 mm OD and will not seat in the chuck. Tube OD must match the printed size precisely. If your line is truly imperial, this resin one-touch catalogue cannot hold it - move to a fitting family made for that tube.
