About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1203-S
The PEB1203-S is an AirTAC male branch tee from the resin one-touch family. It takes Dia 12mm soft nylon or polyurethane tubing into two push-in ports and screws into a 3/8in PT female port through its male stud, creating a 90-degree branch off a straight 12mm run. Push the tube home and the internal chuck grips it against the stainless spring gasket; press the release ring and the tube comes free for rework.
The -S suffix means the male stud is SUS304 stainless steel instead of the standard brass. On this tee family the body itself remains PBT, so the stud thread is what gains corrosion resistance in humid or mildly aggressive plant air. Every rating is unchanged from the standard PEB1203: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The stud arrives with thread sealant already applied.

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 PEB1203-S Is Used
Manifold spare-port branch
Screws into an unused 3/8in outlet on a pneumatic valve manifold of a packaging machine, teeing a 12mm supply line off to an auxiliary reject-blower circuit.
Wash-area rinse feed
The SUS304 stud withstands the humid zone around a bottling-line rinse station, where a brass stud thread would corrode between weekly wash-downs.
Marine deck air spur
Branches a 12mm deck air line on a fishing vessel to feed a winch-control actuator, with the stainless stud resisting salt-laden air at the threaded joint.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1203-S the Right Part?
On the 3/8in rung of the PEB ladder the sizes are 6, 8, 10 and 12mm, so PEB1203-S is the top of that thread group. Step down to PEB1003 for a 10mm branch, or move up to the 1/2in thread with PEB1204 if the port allows it - the tube stays Dia 12 either way, only the thread changes. Push-in chucks hold one exact tube OD: a Dia 12 port will not grip 10mm tube, so check the existing line before ordering.
If the branch needs to pass through a panel rather than hang off a port, the PMF bulkhead female connector is the shape to consider; if the run must swivel to clear an obstruction, the PH universal elbow absorbs the angle instead.
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 PEB1203-S FAQ
It is a one-touch male branch tee joining Dia 12mm soft nylon or polyurethane tube to a 3/8in PT male stud. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum is -750 mmHg, proof pressure is 1.5 MPa and the working temperature range is -20 to +70 C. The body is PBT with a SUS304 stainless stud, POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
No. On PEB tees the -S changes only the stud material to SUS304; the pressure, vacuum, proof and temperature figures and every dimension match the standard PEB1203. AirTAC publishes no separate rating for the stainless option, so you can substitute it one-for-one wherever the brass stud version fits.
