About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB402D
The PEB402D is an AirTAC PEB male branch tee in black, joining a Dia 4 mm tube branch to a 1/4 in PT male thread. The branch leg leaves at 90 degrees from a straight-through run, so you can tee a drop line off a main air path without adding a separate elbow. The D suffix colours the whole body black, not just the button, which is useful on dark machine frames where a grey fitting would stand out.
It uses the resin one-touch profile: push the soft nylon or polyurethane tube fully home and the stainless spring gasket plus POM chuck grip it for a seal rated 0 to 1.0 MPa (0 to 10 kgf/cm2), with 1.5 MPa proof pressure and -20 to +70 C operation; vacuum down to -750 mmHg (10 Torr) is fine. To release, press the ring and pull the tube free. The PBT body carries a brass threaded stud that arrives with sealant already applied, so it screws straight into the port.

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 PEB402D Is Used
Packaging machine drop line
Tee a Dia 4 mm drop off a 1/4 in main run to feed a small vacuum ejector or air jet on a carton-forming station, with the black body disappearing against a dark guards frame.
Valve manifold signal tap
Branch a 4 mm pilot or pressure-switch sensing line off a solenoid manifold port, using the 1/4 in stud to land directly in the tapped gauge or switch connection.
Analytical instrument plumbing
Split a 4 mm polyurethane line feeding an air purge or sample transport circuit inside a laboratory analyser cabinet, where the 90 degree branch keeps routing tight.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB402D the Right Part?
Dia 4 mm is the smallest tube in the PEB ladder - there is no size below it, so if 4 mm is too small you step up to Dia 6 (PEB602D) and gain bore for flow on the same 1/4 in thread. Worth knowing: 1/4 in is the LARGEST thread on PEB that still accepts a Dia 4 tube. The 3/8 in and 1/2 in options start at Dia 6, so if your thread is fixed at 3/8 in you must move the tube up too. Below 1/4 in, both M5 and 1/8 in support Dia 4 on this series.
Match the stud to the port size - a 1/4 in PT stud seals in a 1/4 in tapered port with its pre-applied sealant, and the M5 end of the ladder uses a sealing gasket instead. If you need a tee that passes straight through the panel wall rather than branching off it, that is a PMF bulkhead job, not a PEB.
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 PEB402D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. This SKU joins a Dia 4 mm tube to a 1/4 in PT male thread, in black. Applicable tubing is soft nylon or polyurethane; the body is PBT with a brass stud.
No. On the PEB series, 3/8 in and 1/2 in threads are only made with Dia 6, 8, 10 and 12 mm tubes. Dia 4 is offered with M5, 1/8 in and 1/4 in threads only, which is why this 1/4 in version is the largest-stud option for 4 mm tubing. Also match tube OD exactly - a Dia 4 fitting will not grip 1/8 in nominal tube.
