About the Airtac PE Tee Connector PE4
The AirTAC PE4 is a one-touch union tee from the resin tube-to-tube family: it joins three lengths of Dia 4 mm soft nylon or polyurethane tubing in a single push-in branch, with no threaded port anywhere on the body. Push each tube home and the internal chuck grips the OD; press the release ring and the tube frees again.
This is the resin spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. Like the rest of the one-touch range it also holds -750 mmHg (10 Torr) in vacuum, which matters more often than buyers expect on small signal lines. The grey POM and PBT body is standard; a D suffix on related SKUs switches the colour to black.

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 PE Tee Connector PE4 Is Used
Bench-top fluidic prototypes
Lab rigs built from Dia 4 nylon tubing split a single regulator feed to a sensor, a small actuator and a bleed valve; the PE4 makes that three-way split as a clean push-in junction you can rework in seconds.
Compact gripper pilot circuits
On small pick-and-place heads, the pilot line to a compact gripper valve is commonly Dia 4; a union tee at the wrist lets the same feed branch to a second function without adding a threaded manifold block.
Control cabinet pilot take-offs
Inside a machine electrical cabinet, Dia 4 polyurethane is the usual choice for solenoid valve pilot signals; the PE4 splits one incoming pilot feed to two valve stations while staying inside the wiring duct envelope.
Is the Airtac PE Tee Connector PE4 the Right Part?
PE4 sits at the bottom of the PE ladder. There is no smaller union tee below it in this catalogue, so the only step you can make is up to PE6, where every leg takes Dia 6 mm tube and flow capacity rises with the wider bore. Stepping up only makes sense if the rest of the circuit already runs Dia 6 line; mixing bores needs a reducer shape such as PEG or PEW instead.
Tube OD must match exactly. A Dia 4 PE fitting will not hold a 5/32 inch (4 mm nominal imperial) tube securely because the wall and tolerance differ, and it will never seal on 6 mm. If the connection has to land on a threaded port rather than continue in tube, that is a job for a PEB male branch tee, not this union.
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 PE Tee Connector PE4 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and an operating temperature of -20 to +70 C. It is a tube-to-tube union tee for three lengths of Dia 4 mm soft nylon or polyurethane tubing, with no threaded port on the body.
Use soft nylon or polyurethane tube with a true 4 mm OD; hard nylon or metric-imperial lookalikes will not grip reliably. To release, press the tube inward first, then push the POM release ring squarely toward the body while pulling the tube out. Cutting the tube square and undamaged at the end is what keeps the NBR O-ring seal intact through repeated rework.
