About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB803D-S
The PEB803D-S is an AirTAC PEB male branch tee, the one-touch fitting that turns a single supply run into two without cutting the line. It grips Dia 8 mm soft nylon or polyurethane tube on the branch side and carries a 3/8in PT male thread for the inlet. Push the tube home and the internal chuck jaws close around it; press the POM release ring and the tube slides free again.
This is the -S variant: on the PEB family that means the male stud is SUS304 stainless steel while the body remains the standard PBT moulding, finished in black because the D suffix on PEB changes the body colour, not just the button. Ratings are identical to the grey standard part - 0 to 1.0 MPa working, 1.5 MPa proof, -20 to +70 C - so the stainless stud buys you corrosion resistance on the exposed thread, not a higher rating.

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 PEB T-Shaped Straight Thread Tee Connector PEB803D-S Is Used
Palletiser gate cylinder branch
Tee a Dia 8 drop leg off a 3/8in manifold header to feed the gate-extend cylinder, keeping the main run intact for downstream stations.
Car-wash gate actuator take-off
The SUS304 stud resists the constant wet, detergent-laden air around a vehicle-wash gate cylinder where a plated brass stud would pit over time.
Carton vacuum ejector split
Rated to -750 mmHg, so the same tee can branch a supply line and a vacuum line on a carton-pick station without switching fitting families.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB803D-S the Right Part?
On the 3/8in rung of the PEB ladder, Dia 6 (PEB603-S) and Dia 10 (PEB1003-S) sit either side of this Dia 8 part. Stepping down to 6 mm suits lighter actuator branches; stepping up to 10 mm raises the bore for longer runs where pressure drop starts to matter. If your port is 1/4in or 1/2in instead, PEB802-S and PEB804-S cover the same Dia 8 branch on those threads.
Match the tube exactly: a Dia 8 chuck is machined for an 8.0 mm outside diameter and will not seal on 1/4in (6.35 mm) or 5/16in tube. If you actually need to split one thread into three runs rather than two, that is the PKD triple-branch shape, not the PEB.
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 PEB T-Shaped Straight Thread Tee Connector PEB803D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2); negative pressure down to -750 mmHg (10 Torr); proof pressure 1.5 MPa; operating temperature -20 to +70 C. It joins Dia 8 mm soft nylon or polyurethane tube to a 3/8in PT male thread. The -S version has a SUS304 stud on the standard PBT body, with identical pressure and temperature figures to the grey part.
No. On the PEB branch tee, the -S suffix puts SUS304 on the male stud only; the body stays PBT, as AirTAC publishes it. If you need a solid stainless body, that construction exists on the PC and POC straight connectors, not on this tee. Nothing about the ratings changes either way.
