About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB803-S
The PEB803-S is an AirTAC one-touch male branch tee: a 3/8 inch PT male stud sits at 90 degrees to a straight tube run of two Dia 8 mm ports. Push the soft nylon or polyurethane tube into each collar and the internal chuck grips it instantly; press the release ring and the tube frees again. Unlike a run tee, the branch layout lets you tap off the main airline sideways without re-routing the through flow.
The -S suffix means the male stud and its thread are SUS304 stainless steel, so the wetted thread keeps its integrity where condensate, wash-down mist or corrosive vapour would attack a plain brass stud. The body itself remains PBT with a stainless spring gasket and NBR seals. This fitting belongs to the resin one-touch line, rated 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The PT thread arrives with sealant already applied, so it seals on taper ports straight out of the bag.

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 PEB803-S Is Used
Plating line take-off
On electroplating and anodising lines, acid mist condenses on every brass fitting above the tanks. The SUS304 stud on the PEB803-S threads into the valve manifold feeding rinse-station air cylinders, and the 8 mm ports branch a drop line off the main run without interrupting it.
Marine deck actuation
On fishing-vessel and workboat deck machinery, salt spray reaches the pneumatic control valves behind the wheelhouse. A PEB803-S studs into the PT port of the directional valve, with the Dia 8 mm run carrying supply forward and the 90 degree branch feeding the hatch-lift cylinder.
Palletiser gripper drop
In a palletiser cell, the main 8 mm air run travels along the frame past several stations. This branch tee taps one station off at a right angle, feeding a short drop to the suction or gripper valve while the run continues to the next clamp position.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB803-S the Right Part?
On the 3/8 inch PT row for PEB, Dia 8 mm sits between Dia 6 mm (PEB603-S) below and Dia 10 mm (PEB1003-S) above. Stepping down to 6 mm suits light actuators and shorter runs; stepping up to 10 mm feeds cylinders with heavier air demand. If your port is 1/4 inch rather than 3/8 inch, PEB802-S carries the same Dia 8 mm bore on the smaller thread. Match the tube exactly: this collar grips 8 mm OD soft nylon or polyurethane only and will not hold 5/16 inch (roughly 8 mm nominal imperial) or any other OD.
Choose a branch tee over a straight connector when the supply line must continue past the take-off point and the drop to a valve or actuator needs its own 90 degree outlet. If you need the threaded port in line with the run instead, that is the PED run tee, a different shape.
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 PEB803-S FAQ
It is a one-touch male branch tee for Dia 8 mm soft nylon or polyurethane tube with a 3/8 inch PT male stud in SUS304. Working pressure is 0 to 1.0 MPa, vacuum rating is -750 mmHg, proof pressure is 1.5 MPa and the temperature range is -20 to +70 C. The body is PBT with an NBR seal and stainless spring gasket; only the stud and thread are stainless steel 304.
No. The pressure, vacuum and temperature figures and the dimension tables are identical to the standard version, so it is a direct swap. The only change is the stud material, upgraded from brass to SUS304 stainless steel for corrosion resistance - which is why it suits wash-down and corrosive atmospheres rather than different pressures.
