About the Airtac PE Tee Connector PE4D
The PE4D is an AirTAC PE union tee in the resin one-touch range, joining three pieces of Dia 4 mm soft nylon or polyurethane tube at a single 90-degree branch point with no threaded port at all. Push each tube into its chuck and the stainless spring gasket and NBR O-ring grip and seal it; press the release ring to free it again. The D suffix gives this union a black body rather than the standard grey, and because it is a tube-to-tube union there is no thread sealant involved anywhere on the part.
This is the resin spec profile, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The body mouldings are PBT with a POM release mechanism, an aluminium-alloy guide and a stainless spring gasket. Dia 4 is the smallest bore AirTAC makes in the PE ladder, so the whole fitting is compact enough to sit inside dense tubing bundles.

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 PE4D Is Used
SMT pick-and-place head
A single 4 mm feed routed down the moving head of a surface-mount placement machine splits at the PE4D into two matched branches, each topping a small suction cup line of the same bore.
Analytical instrument pneumatics
Inside a benchtop lab analyser, the black 4 mm tee branches one supply run to a purge jet and a reference-air port without adding a threaded joint that could weep inside the sealed enclosure.
Compact labelling machine valve stack
The outlet of a small solenoid valve serving two 4 mm actuator lines is duplicated through the PE4D, letting one valve drive both grippers on a high-speed label applicator.
Is the Airtac PE Tee Connector PE4D the Right Part?
PE4D sits at the bottom of the PE union tee range - there is no Dia 3.2 tee (that size exists only on the PC and PL mini series), so PE6 is the next step up. Moving to PE6 gains bore for slightly hungrier branch lines but also enlarges the outer body, which matters when the tee has to fit between two other push-in joints on a manifold plate. Keep the tube OD exact: a Dia 4 chuck will not grip 1/4 inch (6.35 mm) tube, and the mismatch will leak or blow off under pressure.
Choose this tee when one 4 mm feed must become two 4 mm branches of equal size. If you need the branch to turn toward a port instead of splitting straight ahead, the PV union elbow is the better shape; if you need unequal bores, step to a different-diameter fitting such as PEG or PEW rather than forcing a reducing bush into the line.
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 PE4D FAQ
The PE4D is a resin one-touch union tee for Dia 4 mm tube on all three legs, with no threaded port. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure goes to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the operating temperature range is -20 to +70 C. It suits soft nylon or polyurethane tube, and the D suffix denotes the black body.
No. The chuck and sealing geometry are sized for exactly 4 mm outside diameter, and a 6.35 mm tube will neither seat in the gasket nor seal on the O-ring. Match the tube OD to the fitting code on every leg, and if you need to bridge 4 mm to 6 mm use a different-diameter fitting from the PE range instead.
