About the Airtac PED T-Shaped Side Thread Tee Fitting PED402-S
The PED402-S is an AirTAC PED male run tee, the stainless-variant version of the resin one-touch family, sized for Dia 4 mm soft nylon or polyurethane tube and a 1/4 inch PT male thread. A run tee is not the same shape as a branch tee: the tube path runs straight through the body and the male thread branches off at 90 degrees, so an existing line can continue undisturbed while a new take-off is added. Push the tube into the chuck and the stainless spring gasket inside grips it; press the release ring and it slides straight back out.
The -S suffix here does not turn the whole fitting into steel. On the PED family AirTAC keeps the body in PBT and upgrades the threaded stud to SUS304 stainless steel, which is exactly where corrosion starts first - the male thread seated in a port. The ratings are identical to the standard part: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. AirTAC ships the thread with sealant already applied, so no extra tape or paste is needed on the 1/4 inch 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.

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 PED402-S Is Used
SMT pick-and-place take-off
On a surface-mount placement head the 4 mm vacuum line runs straight through the tee while the 1/4 inch threaded branch feeds a pressure switch monitoring the gripper circuit - the straight run keeps the existing tubing route untouched.
Analyser dosing manifold
In a laboratory gas analyser, the 4 mm dosing line branches off a 1/4 inch PT port on a reagent manifold; the SUS304 stud resists corrosion where the fitting sits in a washable stainless panel.
Packaging machine drop branch
On a cartoning machine, a 1/4 inch manifold port drops a 4 mm feed to a small sealing jaw cylinder while the through-line continues to the next station from the same fitting.
Is the Airtac PED T-Shaped Side Thread Tee Fitting PED402-S the Right Part?
Dia 4 is the smallest tube this fitting accepts on a 1/4 inch thread - there is nothing below it on this thread, so you are at the bottom of the ladder. Stepping up one size gives the PED602-S (Dia 6 tube, same 1/4 inch thread), which buys you a stiffer line and more capacity through a larger bore. If your port is only 1/8 inch, the PED401-S keeps the same Dia 4 tube on the smaller thread. Remember the tube must match exactly: a Dia 4 chuck will not seal on 6 mm or on inch tube, and forcing it is the usual cause of a leak on first pressurisation. If you need all three connections to turn instead of a straight run, the PEB branch tee (PEB402-S) is the correct shape, not this part.
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 PED402-S FAQ
It is an AirTAC PED male run tee for Dia 4 mm tube with a 1/4 inch PT male thread and a SUS304 stud in a PBT body. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum rating is -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the temperature range is -20 to +70 C. It suits soft nylon or polyurethane tube only, and the stainless variant carries exactly the same ratings as the standard grey part.
No. On this family -S only upgrades the threaded stud to SUS304 stainless steel; the body stays PBT and every published figure - 1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C - is unchanged from the standard PED402. Buyers choose it for corrosion resistance at the thread, not for a higher rating.
