About the Airtac PZ Cross Fitting PZ6
The PZ6 is an AirTAC PZ series union cross: a four-way, tube-to-tube fitting that brings four lengths of Dia 6 mm soft nylon or polyurethane tubing together at one symmetric point, with no threaded port anywhere on the body. Push each tube into its chuck and the internal stainless spring gasket and NBR O-ring seal it instantly; press the POM release ring on that leg to let the tube back out.
This is the resin one-touch spec profile, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The body is PBT with an aluminium-alloy guide, so it stays light even though four chucks are packed into one hub. Because it unions tube to tube, there is no thread to seal - no tape, no sealant, no torque.

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 PZ Cross Fitting PZ6 Is Used
PCB handling gantry
A single 6 mm feed from the valve manifold splits four ways at the cross to run short drops to small bore cylinders on each corner of a pick-and-place gantry, keeping tubing runs equal length.
Laboratory autosampler station
Low-pressure clean air is distributed from one point to four sample stations on a benchtop analyser, where the compact PBT hub fits inside the instrument shroud and the grey body blends with the enclosure.
Belt cleaning nozzles
On a food-grade conveyor line, the cross sits mid-run so one 6 mm supply continues downstream to the next nozzle group while two legs feed air knife jets either side of the belt.
Is the Airtac PZ Cross Fitting PZ6 the Right Part?
Step down to PZ4 when the run is a light pilot or signal line into a small actuator, and up to PZ8 when a single 6 mm branch is feeding more demand than the bore can carry at reasonable velocity - a cross starves all four legs equally, so undersizing it costs flow at every outlet. Tube OD must match exactly: the PZ6 chuck grips 6 mm tube and will not hold 1/4 inch (6.35 mm) hose, which is only 0.35 mm larger.
Choose a cross over a tee when the distribution point itself needs a fourth leg - for example a feed that continues past the branch to the next station. If one leg actually needs a threaded port instead of tube, that is the job of the PZB threaded cross, not the PZ.
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 PZ Cross Fitting PZ6 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Size: a four-way union cross with all four ports accepting Dia 6 mm tubing and no threaded connection. Body PBT, release rings POM, O-rings NBR, spring gaskets stainless. Applicable tubing is soft nylon or polyurethane.
No. The PZ6 accepts 6 mm tube in all four legs - a different-diameter cross is a separate AirTAC part (the PZG series). Also note the tube must be the correct 6 mm OD soft nylon or polyurethane; a 1/4 inch hose at 6.35 mm will not seat in the chuck, and rigid tubing will not seal on the NBR O-ring.
