About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1204D
The AirTAC PEB1204D is a male branch tee in the resin one-touch range: a Dia 12 mm tube port and a second Dia 12 mm tube port on the run, with a 1/2in PT male thread branching off at 90 degrees. It is the largest branch tee on the 1/2in thread row of the PEB ladder, so it sits at the top of the range where main air lines are at their heaviest. The D suffix gives this fitting a black body rather than the standard grey, which is useful where pipework is visible inside a machine and the lines are being colour-managed.
Connection is push-in: the Dia 12 mm tube slides past a stainless spring gasket into a POM chuck that grips the tube wall, and the release ring is pressed to let it back out. The PBT body runs on a brass stud with sealant already applied to the 1/2in PT thread, so it seals straight into a tapered port with no extra tape. This resin profile is rated 0-1.0 MPa (0-10 kgf/cm2) working pressure, 1.5 MPa proof, -750 mmHg vacuum and -20 to +70 C - it is not the metal BPC line, which trades pressure for a 150 C temperature rating.

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 PEB1204D Is Used
Glass plant air main take-offs
On a glass-forming line, the Dia 12 mm main run carries the plant air and each mould-cooling circuit branches off at right angles - the PEB1204D adds that 1/2in threaded branch without cutting the run, in a black body that stays discreet on exposed pipework.
Control-cabinet services block
Large electrical cabinets in a bottling hall often run a Dia 12 mm air spine along the back plate; screwing the 1/2in PT stud through into a valve manifold port gives a clean 90-degree feed from the spine to the valve bank.
Heavy conveyor gate actuation
Pneumatic divertor gates on the 1 m wide conveyor sections of a parcel sortation system use Dia 12 mm lines; this branch tee lets the gate cylinder drop off the main run at a right angle near the transfer point.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1204D the Right Part?
On the 1/2in thread row for PEB, the steps are Dia 8, Dia 10 and Dia 12. The neighbour below is the PEB1004, and stepping down to Dia 10 slimlines the tube run while this PEB1204D keeps the full 12 mm bore for the highest-feed branch. There is no Dia 14 or larger branch tee in this catalogue, so if you need a bigger bore you move to a different fitting family, not a bigger PEB. On the thread side, the PEB1203 (Dia 12 tube, 3/8in PT) is the size down and covers the same bore where the port is a 3/8in tapered hole.
Match the PT thread to the port you are screwing into - the sealant on the stud is designed for a PT taper and M5 ports in this catalogue use a gasket instead. And match the tube exactly: a Dia 12 chuck will not grip 1/2in (12.7 mm) imperial hose or a 10 mm tube, it holds genuine Dia 12 mm soft nylon or polyurethane only.
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 PEB1204D FAQ
It is a resin one-touch male branch tee with a Dia 12 mm tube bore and a 1/2in PT male thread, black (D) body. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure is 1.5 MPa, negative pressure is -750 mmHg (10 Torr), and the working temperature range is -20 to +70 C. It is intended for soft nylon or polyurethane tubing.
No - PEB is a branch tee: the male thread comes off at 90 degrees from the straight run, so the two tube ports stay in line with each other. If you need the threaded port on the centreline splitting the flow into two legs at 90 degrees, the part you want is the PED male run tee in the same Dia 12 mm and 1/2in sizes (PED1204).
