About the Airtac PZ Cross Fitting PZ8D
The AirTAC PZ8D is a one-touch union cross: a four-way tube-to-tube node that joins four lengths of Dia 8 mm soft nylon or polyurethane tubing at a single point, with no threaded port involved. Push each tube firmly into its port and the internal stainless spring gasket and chuck grip the OD to seal it; press the POM release ring square onto the tube and the same tube slides straight back out. Because it is a cross rather than two tees, you get four connections with one body and one potential leak path set instead of two.
This is the D suffix, so the body arrives in black rather than the standard grey - on the PZ union series the D changes the body colour itself, not merely the button as it does on PC and POC. It belongs to the resin/brass one-touch profile: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The body is PBT with a POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring seals.

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 PZ8D Is Used
Bottling line air-jet array
A rinsing or blow-off station on a bottling carousel often needs four jets fed from one supply drop - the PZ8D splits the Dia 8 line four ways without threading a manifold block.
Vacuum-forming cooling header
Sheet-cooling nozzles around a vacuum-forming platen can share a single cross node, letting a technician release and re-route each 8 mm cooling leg individually at the release ring.
Pick-and-place gantry services
On a gantry's moving carriage, a cross keeps four short actuator and sensor lines meeting at one compact black node that stays visible against dark machine framing.
Is the Airtac PZ Cross Fitting PZ8D the Right Part?
Step down to PZ6 when the node feeds lighter lines such as sensor cooling air or a small vacuum ejector, or up to PZ10 when the cross sits on a main distribution leg feeding several downstream branches. Bore is the only thing that changes across the PZ ladder - the shape, the release mechanism and the ratings stay identical - so pick by the tube you already have, not the flow you hope for; capacity follows the 8 mm bore, and AirTAC publishes flow as a characteristic curve only.
All four ports take Dia 8 tube and nothing else - a 6 mm or 5/16 in tube will not seal here, so match the OD exactly. If your node needs a threaded stem into a manifold or valve port instead of a fourth tube, that is 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 PZ8D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), and a working temperature of -20 to +70 C. All four ports accept Dia 8 mm soft nylon or polyurethane tube; there is no threaded port on this part. Flow is published by AirTAC as a characteristic curve only, so size by bore.
Not on the PZ. Every port is Dia 8, because the same chuck and gasket set seals all four ways. If you genuinely need different diameters meeting at one node, move to the PZG different diameter cross; and if one leg must screw into a port rather than carry tube, use the PZB threaded cross instead.
