About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB804-S
The AirTAC PEB804-S is a male branch tee from the one-touch fitting range. Dia 8 mm soft nylon or polyurethane tube runs straight through the two in-line legs, while a 1/2 inch PT male thread on the branch outlet screws into a port or manifold. To connect, push the tube firmly home and the internal stainless spring-gasket chuck grips it; press the POM release ring against the body and the tube frees again, so a branch can be re-routed without cutting tube.
The -S suffix changes the hardware, not the shape or the ratings: the branch stud is SUS304 stainless steel, while the tee body remains PBT and dimensionally identical to the standard PEB804. Spec is the resin profile: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -750 mmHg (10 Torr) vacuum and -20 to +70 C. The thread arrives with sealant pre-applied; the sealing-gasket option applies only to M5 sizes, not to this 1/2 inch part.

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 PEB804-S Is Used
Rinse-valve actuation on a bottling washdown header
Dia 8 tube runs along a filling machine frame and the 1/2 inch branch port drives the rinse valve pilot. The SUS304 stud stands up to damp threads where splash water collects at the port.
Vacuum ejector branch on a carton-erector packaging machine
A Dia 8 main run tees off to feed a ejector for suction cup pick-up. The fitting is rated to -750 mmHg, so the same branch handles the vacuum side without a separate connector.
Air branch to a lab fume-hood sash cylinder
A benchtop fume hood needs a tee to feed its sash-lifting actuator from a lab air line. The PBT body and stainless stud shrug off the humid, chemically laden air around the hood.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB804-S the Right Part?
Dia 8 is the smallest tube AirTAC lists for PEB on a 1/2 inch thread - Dia 4 and Dia 6 do not exist at this thread size. So the step below is a thread step, not a tube step: PEB803-S carries the same Dia 8 tube on a 3/8 inch port where the tapping is smaller. Step up to PEB1004-S for Dia 10 tube when the run feeds a larger cylinder or valve. Whichever you pick, tube OD must match the chuck exactly - a Dia 8 fitting will not hold 10 mm or 5/16 inch tube, however hard it is pushed in.
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 PEB804-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2); negative pressure -750 mmHg (10 Torr); proof pressure 1.5 MPa; temperature -20 to +70 C. This SKU is a male branch tee for Dia 8 mm soft nylon or polyurethane tube with a 1/2 inch PT male branch thread. The -S variant fits a SUS304 stainless stud on the standard PBT body, and the ratings are identical to the non-stainless PEB804.
On the 1/2 inch thread the PEB branch tee ladder starts at Dia 8; the combinations are Dia 8, 10 and 12 only. For a Dia 6 branch tee with a stainless stud, drop to a smaller thread: PEB601-S on 1/8 inch or PEB602-S on 1/4 inch both exist and carry the Dia 6 tube.
