About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB603D-S
PEB603D-S is an AirTAC PEB male branch tee from the resin one-touch range, joining Dia 6 mm tube to a 3/8in PT male thread. The threaded leg screws into the air main or manifold and the branch port takes the 6 mm line at 90 degrees, so you can split a feed without adding a separate union. Push the soft nylon or PU tube home and the internal chuck grips it; press the release ring and the tube frees for rework. The 3/8in thread arrives with sealant already applied.
The -S suffix fits a SUS304 stainless male stud to this tee; the body stays PBT and every dimension matches the standard PEB603D, so it swaps in without redesign. Ratings are the resin-profile figures and nothing else: 0-1.0 MPa working, -750 mmHg vacuum, 1.5 MPa proof, -20 to +70 C. The D suffix selects the black version, and on the PEB family that colour change covers the whole body, not just the release button as it does on PC straight connectors.

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 PEB603D-S Is Used
Branch feed to a pick-and-place gripper
Tee a Dia 6 line off a 3/8in trunk inside the robot cell and feed a compact gripper or small vacuum ejector without stacking an extra union in the harness.
Bottling line washdown frames
The SUS304 stud resists staining at the thread where hose-down water sits, a common failure point on bottle-rinser and filler frames plumbed with brass studs.
Manifold branch at the valve set
Screw the 3/8in thread into the outlet of a directional valve manifold and run the 6 mm branch straight to a pilot line or air table on a packaging machine.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB603D-S the Right Part?
On the 3/8in interface, Dia 6 is the smallest tube AirTAC offers - there is no step below it, and the next rung up is PEB803 with Dia 8 tube, which gives you a stiffer line and more bore for longer branch runs. If the port on your machine is smaller, Dia 6 also pairs with 1/8in and 1/4in threads as PEB601 and PEB602; a Dia 6 tube on a 1/2in thread does not exist in this catalogue. Tube OD must match exactly - the chuck that grips 6 mm will not seal on 1/4in tube, whatever the thread size.
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 PEB603D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. The part joins Dia 6 mm tube to a 3/8in PT male thread on both tube ports. These are the standard resin one-touch figures; the SUS304 stud changes none of them.
On the PEB family it makes the male stud SUS304 stainless steel; the body remains PBT and the release button and chuck stay POM. Pressure, vacuum and temperature ratings and all dimensions are identical to the standard version, so no redesign or re-rating is needed when you specify it.
