About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1204-S
The PEB1204-S is an AirTAC PEB male branch tee in the stainless-stud -S configuration. It takes Dia 12 mm soft nylon or polyurethane tubing into two push-in ports and offers a 1/2in PT male thread at right angles on the branch, so a single 12 mm main run can feed a second leg without a separate elbow. To connect, push the tube straight home until it bottoms; the internal chuck grips the OD, the stainless spring gasket and NBR O-ring seal it, and pressing the POM release ring frees the tube again.
This is the resin one-touch spec profile, not the metal BP line: working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The -S suffix changes the fastening: the body remains PBT, while the threaded stud machined as SUS304 carries the corrosion duty in splash-prone or humid plant air. Every dimension matches the standard PEB1204, so it drops straight into existing drawings.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PEB1204-S Is Used
Palletiser gripper supply
Branching a Dia 12 mm main air run at the end of a palletiser frame to feed a gripper cylinder via the machine's 1/2in branch port, using the tee's push-in ports for fast tube changes during gripper swaps.
Plating shop actuator leg
On a plating line where acidic mist attacks bare brass, the SUS304 stud on the 1/2in branch resists corrosion while the PBT body shrugs off splash - note the tube itself remains the high-temperature limit, not the fitting.
Conveyor stopper station
Tapping a Dia 12 mm supply line along a bottling conveyor to feed a pneumatic stopper or pusher station, with the 1/2in PT thread landing directly on the stopper cylinder's inlet port.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1204-S the Right Part?
On the PEB ladder at a 1/2in thread, Dia 12 is the largest tube offered - the smaller neighbour is PEB1004-S (Dia 10, 1/2in), and nothing sits above it. Stepping down to Dia 10 suits lighter-duty branch lines and a smaller hole through guards; this Dia 12 version is the choice when the main run itself is 12 mm and you want the branch port to be the restriction, not the tee. Tube OD must match exactly: a Dia 12 PEB will not seal or grip 1/2in imperial hose. Match the 1/2in PT thread to a same-size port and use the pre-applied thread sealant rather than extra tape. If the branch must pass through a panel wall instead of ending at a port, the bulkhead-style PMF is the shape to look at (its Dia 12 locknut thread is M22x1).
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 PEB1204-S FAQ
It is an AirTAC PEB male branch tee for Dia 12 mm tube with a 1/2in PT male branch thread (SUS304 stud, PBT body). Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Applicable tubing is soft nylon or polyurethane, and the internal release button and chuck are POM with an NBR O-ring seal.
No. The one-touch chuck in the PEB1204-S is sized for Dia 12 mm outside diameter tubing only; a 1/2in hose (12.7 mm) or 10 mm tube will neither seal nor lock, and pulling it out means damage. Use PEB1004-S for a 10 mm line at the same 1/2in thread. Tube OD must match the code exactly - that is how the gripping collet and O-ring achieve their seal.
