About the Airtac PED T-Shaped Side Thread Tee Fitting PED402D-S
The PED402D-S is an AirTAC PED male run tee, the one-touch fitting shaped as a straight-through run with a 90 degree male branch. This size takes Dia 4 mm soft nylon or polyurethane tube on all three legs of the tee and closes onto a 1/4in PT male thread. Assembly is the standard push-fit action: push the tube fully home, the stainless spring gasket and chuck grip it, and pressing the release collar frees it again.
The -S suffix on a PED does not turn the whole body to stainless. On the PED family the SUS304 stainless steel 304 part is the male stud; the body stays moulded PBT, here in black because the D suffix on series other than PC and POC changes the body colour, not just the button. Ratings are unchanged from the resin line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C.

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 PED T-Shaped Side Thread Tee Fitting PED402D-S Is Used
Pick-and-place branch on an electronics gantry
On a small SMT pick-and-place head, the run tee lets the Dia 4 supply pass straight through to the next station while the 1/4in male branch drops a line to a compact vacuum ejector for component lift-off.
Laboratory analyser air distribution
Inside a benchtop analytical instrument cabinet, a Dia 4 run tee splits one regulated air feed into a straight-through run plus a threaded branch to a purge or actuation port, without tools or tube cutting mid-run.
Pneumatic clamp tapping on a welding jig
A welding fixture with a Dia 4 main line can add a single thumb-size cylinder per station: push the run tee in-line and the 1/4in PT stud feeds the clamp directly at the fixture plate.
Is the Airtac PED T-Shaped Side Thread Tee Fitting PED402D-S the Right Part?
Dia 4 is the smallest tube size on the PED ladder, so there is no smaller sibling. The next step up on the same 1/4in thread is PED602 for Dia 6 tube, which gives you a stiffer, higher-capacity branch for short runs to light actuators. If you want to open the thread instead, note that the 3/8in row on PED starts at Dia 6, so the smallest 3/8in part is PED603 - there is no Dia 4 x 3/8in tee in the catalogue.
A run tee is the right answer when the main line should pass straight through while the male thread taps off at 90 degrees, for example feeding a branch off a manifold run. Check that your port really is 1/4in PT and that the tube is genuinely Dia 4 mm OD: a one-touch chuck sized for Dia 4 will not seal or hold 6 mm or 1/4in imperial tube. The 1/4in thread arrives with pre-applied sealant, so no extra tape is needed.
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 PED T-Shaped Side Thread Tee Fitting PED402D-S FAQ
It is a PED male run tee for Dia 4 mm soft nylon or polyurethane tube with a 1/4in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), proof pressure is 1.5 MPa and working temperature is -20 to +70 C. The -S suffix means the male stud is SUS304 stainless steel 304; the body is black PBT and the chuck and release parts are POM.
No. On angled and tee shapes like the PED, AirTAC fits a SUS304 stainless steel 304 male stud while the body remains PBT. Only the straight PC and POC connectors get a solid stainless body in the -S line. Either way, pressure, vacuum, proof and temperature ratings are identical to the standard grey or black versions, so no re-rating is needed when you substitute.
