About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1203D-S
The PEB1203D-S is an AirTAC PEB male branch tee: a male 3/8in PT thread at the base with two push-in ports that form a 90 degree branch off a straight run of Dia 12 mm soft nylon or polyurethane tube. Push the tube home and the internal chuck grips it under the spring gasket; press the POM release ring and the tube slides free again. AirTAC applies sealant to the PT thread before packing, so the stud seals into the port without extra tape.
This -S version keeps the resin one-touch ratings: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. What changes is the hardware at the port: the male stud is SUS304 stainless steel rather than the usual brass, while the tee body stays PBT in black, the D suffix on this family changing the body colour itself. That stud is the part wetted by spray and condensation at the machine port, so it is the piece that benefits most from stainless on rinse-line and humid builds.

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 PEB1203D-S Is Used
Gripper branch on a palletiser head
Screw the 3/8in stud into the valve manifold outlet and run 12 mm tube to a suction or clamp actuator while the through-run continues to the next station on the palletising head.
Plating and rinse line pneumatics
The SUS304 stud shrugs off the humid, chemical-laden air around plating tanks and rinse stations where a plain brass thread would tarnish and weep at the port seal.
Wash-down conveyor control takeoff
On a food-plant conveyor with periodic hose-down, tee a 12 mm branch off the main 3/8in ported run to feed the divertor cylinder, keeping the wet-side thread stainless.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1203D-S the Right Part?
Step down to PEB1003 for a Dia 10 mm branch on the same 3/8in thread if you are feeding a compact gripper or a smaller actuator - the smaller bore simply carries less air through the branch leg. Dia 12 mm is already the top of the tube ladder on the 3/8in row for PEB, so to go larger on the thread side you move to PEB1204, which keeps the 12 mm tube but steps the male thread up to 1/2in PT for big manifold ports. Match the port, then match the tube: a Dia 12 mm chuck will not seal on 1/2in (12.7 mm) imperial hose, which is a different catalogue entirely. If you need the branch to pass straight through a panel wall instead of screwing onto a port, the bulkhead shapes PM or PLM are the right answer, not this tee.
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 PEB1203D-S FAQ
It is a PEB male branch tee joining Dia 12 mm soft nylon or polyurethane tube to a 3/8in PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The tee body is black PBT, the male stud is SUS304 stainless, and the release ring and chuck are POM with an NBR O-ring seal.
No. The stainless version keeps exactly the standard figures - 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C - and the dimension tables match the standard part. Only the male stud material moves from brass to SUS304, which buys corrosion resistance at the port; nothing else is re-rated, so you can swap it into an existing PEB1203D position without touching the circuit.
