About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB804D-S
A PEB is AirTAC's male branch tee in the resin one-touch range: a Dia 8mm push-in port on each of the two run ends and a 1/2 in male PT branch at 90 degrees, all in one moulded body. Push 8mm soft nylon or polyurethane tubing into a port until it bottoms out; the stainless spring gasket and POM chuck grip the tube under spring load, and pressing the release ring frees it again. On the PEB series the D suffix makes the body itself black, not just the release button as on the straight PC and POC connectors.
The -S option changes only the stud, which is SUS304 instead of the standard brass, so the thread meeting your port resists corrosion in damp or wash-down locations. The body remains PBT, and no rating moves: working pressure 0 to 1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa, temperature -20 to +70 C. AirTAC ships the stud with sealant already on the thread, so the 1/2 in PT branch seals into the port without extra tape.

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 PEB804D-S Is Used
Wash-down conveyor take-off
On a fish-processing line, branch off the main 8mm air run to feed a knife-actuation cylinder: the SUS304 stud resists corrosion in the wet stainless port block while the main line continues straight through.
Pick-and-place ejector feed
A gantry suction station needs vacuum at a 90 degree branch. Tee the Dia 8 line just before the vacuum ejector so the palletising head and the part-present sensor leg share one supply.
Carton-sealer clamp branch
At the manifold of a case-sealing machine, run the Dia 8 main line past the frame and branch into a 1/2 in PT port to feed the box-clamp cylinder, keeping the run intact for the next station.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB804D-S the Right Part?
Dia 8 is the smallest tube AirTAC pairs with a 1/2 in thread on the PEB ladder, which runs 8, 10, 12 at this thread, so there is nothing below it; step up to the Dia 10 version when the run continues in larger tubing. If your branch port is 3/8 in instead, that row starts at Dia 6, giving you PEB603D-S. A branch tee is the right shape when you need a 90 degree take-off while the main line keeps flowing straight through the run - a male elbow (PL) would dead-end the line instead. Whichever size you order, tube OD must match exactly: a Dia 8 chuck will not seal on 6mm or 10mm 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 PEB T-Shaped Straight Thread Tee Connector PEB804D-S FAQ
Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), with negative pressure to -750 mmHg and a proof pressure of 1.5 MPa. Temperature range is -20 to +70 C. This SKU joins Dia 8mm tubing to a 1/2 in male PT branch thread, with a PBT body, POM chuck and a SUS304 stud carrying pre-applied thread sealant.
No. On the PEB family the -S option converts only the stud to SUS304; the body stays PBT, the chuck and release button POM, and the O-ring NBR. All pressure and temperature ratings are identical to the standard grey version. AirTAC reserves the solid stainless-steel body for the -S versions of the PC and POC straight connectors.
