About the Airtac PED T-Shaped Side Thread Tee Fitting PED803D-S
The PED803D-S is an AirTAC PED male run tee in the stainless-stud (-S) configuration with a black (D) body. It pushes onto Dia 8 mm soft nylon or polyurethane tubing on two in-line legs and screws into a 3/8 PT male port with the third leg at 90 degrees. The thread standard for this catalogue is PT throughout, and threaded studs arrive with sealant already applied. Like every one-touch fitting in the range, you seat the tube by pushing it home until the internal chuck grips it; pressing the POM release ring frees it again without tools.
This is the resin/brass spec profile, not the 0.9 MPa metal line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a service range of -20 to +70 C. On this PED family the -S suffix means the stud is SUS304 while the body stays engineering polymer, finished black here because the D code on this series changes the body itself (unlike PC/POC, where D only changes the release button). Ratings, thread ladder and dimensions are identical to the grey PED803.

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 PED803D-S Is Used
Plating and wet-process line branch
Tee off a Dia 8 header to an air-driven diaphragm pump or agitator on a plating line, where the SUS304 stud resists corrosive atmospheres far better than plain brass on the one component that is actually threaded into the fixture.
Press-machine dual-cylinder feed
Screw the run tee directly into the 3/8 PT manifold port of a pneumatic press and continue the Dia 8 run to a second actuator, feeding both from one port without a separate junction block.
Fixture clamping circuit with mid-run tap
Use the in-line body to extend a Dia 8 supply along a weldment fixture and take a 90-degree branch to a swing clamp, screwing the SUS304 stud straight into the clamp base port.
Is the Airtac PED T-Shaped Side Thread Tee Fitting PED803D-S the Right Part?
On the 3/8 PT row of the PED ladder, Dia 8 sits between Dia 6 (PED603-S) and Dia 10 (PED1003-S). Stepping down to Dia 6 trims the bore for lighter-actuation circuits and shorter runs; stepping up to Dia 10 lowers restriction for longer lines or larger-bore cylinders. For this Dia 8 tube size the adjacent thread options are 1/4 (PED802-S) and 1/2 (PED804-S), so match the stud to the actual port, not to habit. If you need a straight union instead of a threaded tee, that is the PE series; if the tee must pass through a panel wall, the PMF bulkhead female connector is the right shape. Tubing OD must match exactly: a Dia 8 chuck will not reliably hold 6 mm or 10 mm tube.
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 PED803D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. This SKU joins Dia 8 mm soft nylon or polyurethane tubing to a 3/8 PT male thread and is the SUS304-stud, black-body variant. These figures are identical to the standard grey PED803.
No. On the PED family the SUS304 part is the threaded stud, which is the surface most exposed to the port and the atmosphere around it; the body remains engineering polymer, here finished black. Pressure, temperature and dimensional data are unchanged from the standard version, so you can substitute it anywhere the PED803 is already specified.
