The AirTAC Airtac PZ Cross Fitting PZ10 is a genuine cross for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The AirTAC PZ10 is a one-touch union cross: a four-way tube-to-tube junction that joins four Dia 10 mm soft nylon or polyurethane tubes at a single balanced point, with no threaded port anywhere on the body. Push each tube home and the internal chuck grips the outer wall against the stainless spring gasket; press the release ring and the tube slides free. All four legs are identical, so any port can serve as the inlet.
PZ belongs to the resin one-touch family, so it carries the resin ratings: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -750 mmHg (10 Torr) vacuum and -20 to +70 C. The release button and chuck are POM, the guide is aluminium alloy and the O-ring is NBR, in the standard grey finish. Order the D suffix for black, which changes the body colour on this series rather than just the button.

Splitting one Dia 10 supply line four ways on a carton palletiser head, feeding parallel gripper circuits at equal pressure from a single junction.
Tying four Dia 10 drops into one clean-air header above a rotary rinser, so every nozzle sees the same supply without extra threaded joints in the wet zone.
Joining vacuum generator, reservoir and two gauge lines on a bench that runs down to -750 mmHg, with a spare Dia 10 PP plug turning the cross into a tee.
Step down to PZ8 or up to PZ12; both exist in this ladder. Dropping to Dia 8 shrinks the bore feeding all three outlet legs, which costs capacity on longer or hungrier circuits, while Dia 12 adds margin for heavier actuator runs. If the branches need different diameters, that is a job for the PZG different-diameter cross, not the PZ10. If the supply arrives on a threaded stub, the PZB threaded cross is the correct shape and the port thread is matched first.
Tube OD must match exactly either way: a Dia 10 port will not seal on 3/8 in (9.5 mm) tube even though the difference looks trivial on a ruler.
Quick checklist
The PZ10 is a resin one-touch union cross for four Dia 10 mm tubes. Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), temperature -20 to +70 C. Tubing must be soft nylon or polyurethane. There is no thread on the body; the bulkhead locknut sizes used by the PM family do not apply here.
Yes. Seal one leg with a Dia 10 PP plug from the same one-touch range and the cross works as a balanced union tee, keeping a fourth branch available for later. Never blank a leg with tape or a mis-sized tube; the chuck and gasket are made for exactly Dia 10 OD and anything else will leak or blow off under pressure.
