About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1204D-S
The PEB1204D-S is AirTAC's PEB male branch tee in its largest arrangement: Dia 12 mm tubing on a 1/2in PT male thread, finished in the D black body colour, with the male stud machined in SUS304 stainless steel. Unlike a run tee, the branch port leaves the through-line at 90 degrees while both tube legs stay in line, so a tee can be spliced straight into a main drop and the branch still points exactly where the actuator needs it. Push the 12 mm tube home and the internal chuck grips it; press the release ring and it frees.
This is the resin/brass spec profile, not the metal 0.9 MPa line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C, for soft nylon or polyurethane tubing. The stud arrives with sealant already on the PT thread, and the release button, chuck and NBR O-ring carry over from the standard PEB - the -S change is the stud material, not the shape or the ratings.

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 PEB1204D-S Is Used
Palletiser drop-line branch
Splice the tee into a 12 mm vertical drop on a palletising cell and branch off at 90 degrees to feed the gripper cylinder, without re-routing the main line.
Belt cleaner actuator take-off
On a conveyor head pulley, a 1/2in PT port on the air header takes the stud while the 12 mm legs carry the main supply past to the next station.
Wash-down rinse header branch
The SUS304 stud suits a food-plant rinse cabinet where the 1/2in branch feeds a spray-bar valve from a copper-free-sensitive line.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1204D-S the Right Part?
On the 1/2in thread you can step down to PEB1004D-S (Dia 10 mm), the only smaller tube size AirTAC lists on 1/2in for PEB; going below that means dropping to a 3/8in stud. On the tube side, PEB1203D-S keeps the full Dia 12 bore but reduces the stud to 3/8in PT, useful when the port is smaller than the line. There is no step up: Dia 12 is the largest tube and 1/2in the largest thread in the PEB ladder, so this SKU is the top of the range. Whichever way you go, tube OD must match exactly - a Dia 12 chuck will not seal on 10 mm or on 1/2in imperial tube.
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-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The tube diameter is 12 mm on both through legs and branch, the male thread is 1/2in PT, and the D suffix is AirTAC's black body colour.
No. On PEB parts the -S makes the male stud SUS304 stainless steel; the body stays PBT, and the pressure, temperature and size tables are identical to the standard PEB1204D. Buyers who need a fully stainless body are directed to the PC or POC straight connectors, where the body itself is 304.
