About the Airtac PED T-Shaped Side Thread Tee Fitting PED401-S
The PED401-S is an AirTAC male run tee: a straight Dia 4 mm tube run that passes through the body, with a male 1/8in PT branch at 90 degrees for screwing straight into a valve, manifold or cylinder port. The one-touch action needs no tools - push the soft nylon or polyurethane tube fully home and the stainless spring gasket plus chuck clamp it; press the POM release ring and the tube slides free. On this -S variant the threaded stud is SUS304 stainless steel, while the body itself stays PBT.
This is the standard resin-brass spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. AirTAC supplies the 1/8in PT thread with sealant already applied, so the branch seals on first assembly without extra tape. Note the material split honestly: the corrosion benefit of the -S suffix sits in the stud, so spec it where the wet, splashed or marine side of the joint is the threaded side.

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 PED401-S Is Used
Valve manifold branch on a packaging machine
Tees a 1/8in PT pilot signal off a Dia 4 nylon run that continues straight through to the next station, keeping the main line uninterrupted along the machine frame.
Pick-and-place head on a small assembly robot
The Dia 4 branch feeds a compact gripper cylinder while the through-run carries supply onward, and the 90 degree male thread mounts flush against the end-effector plate.
Splash-zone sensing lines in an electroplating workshop
The SUS304 stud resists corrosive mist at the threaded connection into solenoid valves, where plated or chemical-laden air would attack a plain brass stud over time.
Is the Airtac PED T-Shaped Side Thread Tee Fitting PED401-S the Right Part?
Dia 4 is the smallest tube size the PED family is made in, so there is no step down on tube - the only way to go smaller is the M5 thread version, PED40M5-S, which still takes Dia 4 tube. Step up to PED601-S for Dia 6 tube on the same 1/8in thread; the larger bore moves noticeably more air per metre of run, which matters once your line exceeds a few metres or feeds more than one small consumer. On the thread axis, PED402-S goes to 1/4in PT if the receiving port is the larger standard. Whichever you pick, the tube OD must match the fitting exactly - a Dia 4 chuck cannot seal 5/32in or 1/4in tube, and no adapter changes that. Choose a run tee rather than a branch tee (PEB) when the main line should continue straight through and only the branch turns 90 degrees; for a panel-wall pass-through you need PMF 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 PED T-Shaped Side Thread Tee Fitting PED401-S FAQ
It is a male run tee for Dia 4 mm soft nylon or polyurethane tube with a 1/8in PT male thread and SUS304 stud. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it handles vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. The POM chuck and release button, aluminium-alloy guide and NBR O-ring are unchanged from the standard PED.
No. In the PED family the -S suffix makes the threaded stud SUS304; the body remains PBT, the same shape and dimensions as the standard part, and the published pressure and temperature ratings are identical. Spec it for corrosion exposure at the threaded interface, and remember that at elevated temperatures the tube itself, not this fitting, is usually the limiting component.
