The AirTAC Airtac PED T-Shaped Side Thread Tee Fitting PED1004-S is a genuine male run tee for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PED1004-S is the SUS304-stud version of AirTAC's PED male run tee, a one-touch fitting that joins Dia 10 soft nylon or polyurethane tubing to a 1/2in PT male thread. A run tee is not the same shape as the PEB branch tee: the threaded leg sits in line with the through-flow, so the main air line carries straight through the body while the branch drops off at 90 degrees. That geometry makes PED the natural choice when a line must continue downstream and still feed a take-off.
Connection is push-in: the tube slides past the stainless spring gasket and the gripper chuck clamps it; pressing the POM release ring frees it again. The -S suffix changes only the stud metal - brass becomes SUS304 - while the body remains PBT, so every rating of the resin line holds unchanged: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -750 mmHg vacuum and -20 to +70 C. Each threaded stud arrives with sealant already applied, ready to wind into the port.

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.

Beside electroplating and rinse tanks, acid mist quickly pits brass studs. Here the SUS304 stud and PBT body of the PED1004-S take the 1/2in drop from a main run straight down to a lift or agitate cylinder.
In a corrugated box plant the main line runs along the glue station frame; the run tee lets flow continue to the next station while the 90 degree branch drops Dia 10 tubing to a glue-valve cylinder.
On fishing-boat and workboat decks, salt spray attacks plated brass within a season. Branching a 1/2in deck run to a hatch-closing ram with a stainless-stud tee extends the service interval of the branch point.
On the 1/2in rung of the PED ladder exactly three bores exist: Dia 8, Dia 10 and Dia 12. Step down to PED804-S for a lighter branch feeding a single small cylinder; step up to PED1204-S when the tee sits on a header that serves several take-offs and bore losses matter. This SKU is the middle of that ladder - enough bore to branch a full-size actuator without the bulk of the Dia 12 body.
Match the 1/2in PT thread to a PT-tapered port; this catalogue documents PT only, so an NPT or G port needs a different part. The socket takes exactly Dia 10 outside-diameter tubing - a 3/8in (9.5 mm) or 12 mm tube will not seal in it, and soft nylon or polyurethane are the only tube materials rated for the chuck.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg, temperature -20 to +70 C. The fitting accepts Dia 10 soft nylon or polyurethane tubing and carries a 1/2in PT male thread. These are the resin-profile figures; the -S suffix changes the stud material only, not any rating.
No. In AirTAC's -S scheme for the PED family, the brass stud is replaced by SUS304 while the body stays PBT, so the tube sockets and release ring are unchanged from the standard PED1004. If your wash-down or corrosion exposure reaches the body as well, that is a reason to review the whole line material - not a reason to assume this part is solid stainless.
