About the Airtac PED T-Shaped Side Thread Tee Fitting PED402
The PED402 is an AirTAC PED male run tee, a one-touch fitting that turns a single 1/4in PT male port into three connections: a straight 4mm line passing through the body plus a 90 degree branch off the same axis. Unlike a branch tee, where the leg sits perpendicular to the flow path, a run tee keeps the main run inline so a pressure switch, gauge or secondary actuator can hang off an existing straight run without adding bends.
Tube is pushed into the chuck until it seats; the stainless spring gasket and NBR O-ring seal it, and pressing the POM release ring frees the tube again. This is the resin fitting profile, not the metal line: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The body is PBT with a brass stud, and the stud ships with thread sealant already applied, so no PTFE tape is needed on installation.

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 Is Used
Teeing a pressure switch off a packaging machine pilot line
On a rotary filler, the 4mm nylon pilot line feeding a cylinder valve can be tee'd straight through the PED402 so a compact pressure switch branches off mid-run, keeping the sensing point on the same axis as the flow instead of at a hard corner.
Splitting a signal line in a laboratory gas or analyzer skid
Benchtop test rigs built from 4mm PU tubing often need one regulated supply sent to two points. The run tee's inline geometry keeps the original tube run straight between regulator and instrument while the second leg drops down to a purge valve or reference port.
Adding an air blast nozzle to a pick-and-place gantry
On a small component-handling gantry, the 1/4in PT stud on the manifold block feeds the tee, and the 4mm through-line continues to the vacuum ejector while the branch leg supplies a brief clean-down blast at the gripper station.
Is the Airtac PED T-Shaped Side Thread Tee Fitting PED402 the Right Part?
Dia 4 on a 1/4in thread is actually the top of this tube's ladder: the PED range offers Dia 4 only in M5, 1/8in and 1/4in, because the 3/8in and 1/2in threads begin at Dia 6. If you need a smaller port, step down to PED401 (1/8in) or PED40M5; if your circuit carries more flow, move the whole ladder up to PED602, which puts a Dia 6 bore behind the same 1/4in thread and reduces restriction on longer runs. Remember the tube OD must match exactly - a Dia 4 fitting will not grip 1/4in (6.35mm) imperial or 5/32in tube, and soft nylon or polyurethane are the only tubing types covered by the specification.
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 FAQ
It is a resin one-touch male run tee joining 4mm OD soft nylon or polyurethane tube to a 1/4in PT male thread. Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The body is PBT with a brass stud, POM release ring, stainless spring gasket and NBR O-ring.
No tape needed: AirTAC applies thread sealant to the 1/4in stud before dispatch, so it seals straight into the port. The difference from a PEB is geometry - on this run tee the 4mm branch rises off a continuous straight through-line, whereas on a branch tee the third leg sits perpendicular to the flow path. Choose the run tee when you want the main line to stay visually and hydraulically straight.
