About the Airtac PED T-Shaped Side Thread Tee Fitting PED401D-S
The PED401D-S is an AirTAC male run tee from the resin one-touch fitting family, joining two Dia 4 mm tube lines in a straight through-run while a 1/8 inch PT male thread branches off at 90 degrees. Push the soft nylon or polyurethane tube into each port and the internal chuck grips it positively; press the release ring to free it. The D suffix gives the black body colourway.
The -S variant keeps the standard resin spec - 0-1.0 MPa working pressure, -750 mmHg vacuum and -20 to +70 C - and does not change the dimensions. What it changes is the fixing stud: on PED-family parts the body stays PBT while the threaded stud is SUS304, so the leg that screws into your port resists corrosion and stands up to humid or washdown-adjacent panels. The thread ships with sealant applied, so a wrench-and-go install is normal; the M5 sizes in this catalogue are the ones that use a sealing gasket instead.

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 PED401D-S Is Used
Analytical instrument sample-air tee
Split a 4 mm sample-air line inside a benchtop gas analyzer: the run continues to the cell while the 1/8 inch PT branch feeds a low-pressure switch, with the SUS304 stud coping with humid exhaust-side air.
SMD pick-head vacuum branch
On a desktop pick-and-place head, run the Dia 4 vacuum line straight through between nozzles and take the 1/8 inch threaded branch to a compact vacuum filter or sensor.
Pilot-signal tap on an air-jet loom
Tap a Dia 4 pilot line on a textile loom's jet-control manifold: the main signal passes through the tee and the threaded leg carries the small pressure gauge used for jet timing setup.
Is the Airtac PED T-Shaped Side Thread Tee Fitting PED401D-S the Right Part?
Dia 4 is the smallest tube size AirTAC makes in this series, so there is no smaller sibling - if you step down from here you change technology, not size. On the same 1/8 inch thread the next rung up is PED601 (Dia 6), which adds bore for slightly hungrier actuators; on the same Dia 4 tube the thread options are PED4M5 with its M5x0.8 gasket-sealed port or PED402 for a 1/4 inch port. Match the thread to the receiving port first, then confirm tube OD: a Dia 4 chuck will not seal on 1/8 inch (3 mm) imperial tube, which is a different catalogue entirely.
Choose a run tee over a branch tee when the incoming line must continue straight through to a second leg - for example a probe line feeding onward to another station - with the threaded port kept for the gauge, pilot valve or vacuum generator on the branch.
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 PED401D-S FAQ
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. It joins Dia 4 soft nylon or polyurethane tube to a 1/8 inch PT male branch thread. Construction is a black PBT body with SUS304 stud, aluminium-alloy guide, stainless spring gasket, POM release button and NBR O-ring.
No, and knowing this avoids surprises. On PED-series parts the -S means the threaded stud is SUS304 while the body remains PBT (only the PC and POC straight connectors get a full SUS304 body). Pressure, vacuum, temperature ratings and all dimensions are identical to the standard PED401D, so nothing needs re-rating on your drawing.
