About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB603-S
The PEB603-S is an AirTAC PEB male branch tee in the stainless -S configuration, joining Dia 6 mm soft nylon or polyurethane tubing to a 3/8in PT male thread set at 90 degrees to the through-run. Push the tube into the chuck and the internal grip plus stainless spring gasket lock it straight away; press the POM release button ring and the tube slides back out. The 3/8in thread leaves the AirTAC factory with sealant already applied, so no tape or paste is needed on assembly.
Because this code carries the -S suffix, the threaded stud is stainless steel 304 while the tee body remains the standard PBT - on branch tees the -S is a stud upgrade, not a solid stainless body, so specify it for the corrosion-exposed thread side of the joint. Ratings stay exactly those of the resin line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. One non-obvious point from the interface table: on the PEB prefix, 3/8in is the largest thread offered in Dia 6, and Dia 6 is the smallest tube that 3/8in accepts - this SKU sits at a true corner of the ladder.

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 PEB603-S Is Used
Manifold branch feed on packaging machines
Screw the 3/8in stud into a main manifold port and take a Dia 6 branch off at 90 degrees to feed a small packaging cylinder or vacuum ejector without adding a separate elbow and nipple.
Wash-prone zones on food-handling equipment
Where machine frames get hosed down regularly, the SUS304 threaded stud resists corrosion at the port interface on rinsing or filling stations, while the PBT body keeps the fitting light and cost-effective.
Gripper and tooling circuits on robotic cells
The compact branch tee lets a Dia 6 service line split into two directions beside a robotic gripper or tool changer, where a straight run plus elbow would add length the cell layout cannot spare.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB603-S the Right Part?
This part occupies a corner of the PEB interface table, so both neighbours are worth knowing. Stepping the thread down one size gives PEB602, the same Dia 6 branch tee on a 1/4in PT stud, which suits smaller valve and cylinder ports. Stepping the tube up on the same 3/8in thread gives PEB803, which moves the branch bore to Dia 8 and increases the air path area for higher-demand branches. There is no Dia 4 option on 3/8in for this prefix, and no larger thread than 3/8in in Dia 6.
Match the stud to the port before anything else: a 3/8in PT male thread wrenches into a tapped port of the same size, and the pre-applied sealant does the sealing rather than a gasket. Check the tube is exactly Dia 6 mm outside diameter - a one-touch chuck sized for Dia 6 will not seal 1/4in (6.35 mm) imperial tube, and that mismatch is the most common cause of a slow leak on mixed imperial-metric machines.
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 PEB603-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 6 mm soft nylon or polyurethane tube to a 3/8in PT male thread. It is the -S variant, so the stud is SUS304 and the tee body is PBT, with a POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
The tube must be exactly Dia 6 mm OD. AirTAC's one-touch interface table lists Dia 6 as the smallest tube size the PEB prefix offers on a 3/8in thread, so there is no Dia 4 reducer option here, and the chuck cannot reliably grip an undersized or imperial 1/4in tube. If you need a reduced branch, use the dedicated reducer family such as PKD or PG instead.
