About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB4M5
The PEB4M5 is an AirTAC PEB male branch tee, the threaded three-way fitting that divides a single M5x0.8 supply port into two push-in branches. On this SKU both branch ports accept Dia 4 mm tube, so one small controller or manifold outlet can feed two separate lines without an extra union. Push the tube straight into the port and the stainless spring gasket inside the chuck grips it; press the POM release ring and the tube comes straight back out.
This belongs to the resin and brass one-touch family, rated 0-1.0 MPa (0-10 kgf/cm2) working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C, for soft nylon or polyurethane tubing in the standard grey finish. Unlike the larger PT threads in the range, the M5 stud is sealed by a gasket rather than pre-applied thread sealant, so it seats metal-to-metal against a tapped M5x0.8 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 PEB4M5 Is Used
Miniature pick-and-place grippers
An M5 supply port on a compact parallel gripper or rotary actuator often needs two feeds - one for each chamber or for a paired vacuum cup. The PEB4M5 splits that single M5 outlet into two Dia 4 mm runs routed along the robot arm.
Laboratory and analytical instrument air
Bench-top lab devices and small dosing heads run low-flow pneumatic circuits on 4 mm tubing tapped at M5. A branch tee at the instrument's inlet lets one filtered supply line serve both a pilot circuit and a process circuit without adapters.
Electronics fixture air jets
PCB inspection and test fixtures use short 4 mm air jets driven from M5 ports on the fixture frame. Fitting a PEB4M5 at the frame port feeds two jets symmetrically from one supply, keeping the fixture lid thin and the wiring loom clear.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB4M5 the Right Part?
Dia 4 mm is the smallest tube bore the PEB series offers on M5, so the only step from here is up: PEB6M5 takes Dia 6 mm tube and moves noticeably more air for a tiny increase in diameter, which matters on a crowded M5 manifold. There is no Dia 3.2 mm branch tee in the PEB ladder - mini sizes like that exist only on PC and PL - so if your machine really runs 4 mm line, this is the right starting point. Note that M5 on the PEB supports only Dia 4 and Dia 6; stepping to the 1/8 in version (PEB401 upwards) is what opens the 8, 10 and 12 mm ladder.
Check the receiving port before ordering: it must be tapped M5x0.8 and flat enough for the gasket to seal. Tube OD has to match exactly - this tee will not grip 3 mm or 5 mm tube, and it is not the fitting for 1/4 in line even though 4 mm looks close to it.
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 PEB4M5 FAQ
It is an AirTAC PEB male branch tee with a Dia 4 mm push-in tube size on both branches and an M5x0.8 male thread with gasket seal. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa and operating temperature -20 to +70 C. It is intended for soft nylon or polyurethane tubing and arrives in the standard grey finish.
No tape: M5 sizes in this range seal with a sealing gasket on the stud instead of the pre-applied sealant used on the 1/8 in and larger PT threads, so just seat it squarely against the port. On the tube side, no - the chuck is sized for 4 mm OD only and will not grip fractional 1/4 in tubing; order a fitting whose published tube size matches your tube exactly.
