About the Airtac PED T-Shaped Side Thread Tee Fitting PED803-S
The PED803-S is an AirTAC PED male run tee in the one-touch fitting range, sized for Dia 8 mm soft nylon or polyurethane tube with a 3/8in PT male thread. A run tee differs from a branch tee in one practical way: the tube path runs straight through the body and the threaded port sits at 90 degrees on the run, so it can be spliced into an existing air line without turning the line. Push the tube into the chuck until it stops and the stainless spring gasket and POM chuck grip it; press the release ring to free it.
This is the resin profile, not the metal BPC line: working pressure 0-1.0 MPa, vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. The -S suffix fits a SUS304 stud in place of the brass one; the body stays PBT and every pressure and temperature figure is unchanged, so spec it for stud corrosion resistance in wet areas, not for extra pressure.

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 PED803-S Is Used
Bottling line rinse section
On a bottling plant's rinse-and-fill deck, the constant spray and occasional caustic foam attack brass studs on inline fittings. The SUS304 stud on the PED803-S keeps the tee's thread connection sound while the straight run continues downstream to the filler's reject-blow valves.
Venturi vacuum ejector tap
Rated to -750 mmHg (10 Torr), this tee can be spliced into a Dia 8 mm supply run and its 3/8in port used to feed a compact venturi ejector on a pick-and-place gantry, with the main run carrying on to the next drop without an extra coupling.
Machining centre valve manifold feed
Where a Dia 8 mm supply line passes a machine tool's valve manifold, the run-through path lets the line continue to a second manifold while the 3/8in branch drops down to the directional valve port, all through one fitting in the line rather than a tee plus connector.
Is the Airtac PED T-Shaped Side Thread Tee Fitting PED803-S the Right Part?
Both neighbours on this ladder are real parts: step down to Dia 6 (PED603) for a lighter branch on the same 3/8in port, or step up to PED1003 when the run carries a larger cylinder or valve supply. Note that 3/8in is the most flexible thread in the PED range, spanning Dia 6 to Dia 12, while a 1/8in PED tops out at Dia 10 - so 3/8in leaves you room to resize the tube later without changing the thread. The thread arrives with sealant already applied, so it goes straight into a PT port; the matching run tee with 90-degree flow through is the PEB branch tee shape only if you need the port in the flow path, which you usually do not.
Tube OD must match exactly: this chuck holds Dia 8 mm only and will not seal on 1/4in (6.35 mm) or 5/16in (8 mm nominal but off-spec) tubing.
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 PED803-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, working temperature -20 to +70 C. The fitting takes Dia 8 mm soft nylon or polyurethane tube and has a 3/8in PT male thread. The -S variant uses a SUS304 stud; all ratings are identical to the standard PED803.
No. The body, release button, chuck and sealing parts are the same, and AirTAC's dimension tables match the standard version, so panel cut-outs and spacing are unchanged. The SUS304 replaces the brass stud only, which matters in wet, rinsed or humid zones where brass studs stain or corrode. Keep the same 0-1.0 MPa / 70 C limits and use Dia 8 mm tube - a smaller or larger tube will not seal.
