About the Airtac PZ Cross Fitting PZ6D
The PZ6D is an AirTAC PZ series one-touch cross, a four-way tube-to-tube union with every port cut for Dia 6 mm soft nylon or polyurethane tubing. The D suffix orders it in black rather than the standard grey, and on the PZ line the black colour carries through the body. Push each tube into its port and the internal chuck grips the OD; press the release ring and the tube frees again.
This is the resin one-touch 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 -20 to +70 C temperature window. The fitting pairs a POM chuck and release button with an aluminium-alloy guide, stainless spring gasket and NBR O-ring, so the seal stays elastic across the whole rated temperature range.

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 PZ6D Is Used
Four-cup gripper node on robot EOAT
End-of-arm tooling often needs supply air split to four suction cups or grippers at one compact point. A PZ6D makes that branch in a single body that weighs little at the wrist and releases tubes with a finger press during changeover.
Air purge array in a lab rinse station
A benchtop wafer or glassware rinsing station blowing four short 6 mm purge jets can share one feed through this cross. The NBR seals handle the -20 to +70 C window of a laboratory compressed-air loop without drying out.
Web cleaner jet split on a press
Printing and converting presses use banks of 6 mm air knives to strip dust from the web. A PZ6D lets one drop feed four jet heads symmetrically, keeping flow even across the station without stacking fittings behind the guard.
Is the Airtac PZ Cross Fitting PZ6D the Right Part?
On the PZ cross ladder this Dia 6 node sits between PZ4 below and PZ8 above. Stepping to PZ4 suits light pilots and small signal lines; stepping to PZ8 buys lower restriction on longer runs, since flow capacity on this family follows the tube bore rather than a published Cv. Tube OD must match exactly: Dia 6 is 6.0 mm, and a nominal 1/4 inch tube measures 6.35 mm, so it will not seal in a PZ6D.
Choose a cross instead of two union tees joined by a short jumper when four equal lines meet at one point. The swap removes two joints from the circuit - four push-in seals on one body versus six across a tee-pair - which is two fewer potential leak sites to chase during commissioning.
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 PZ6D FAQ
It is a four-way one-touch cross union with all ports for Dia 6 mm soft nylon or polyurethane tube and no thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa and operating temperature -20 to +70 C. The D suffix specifies the black body version of the standard grey PZ6.
No. A 6 mm port is machined for a 6.0 mm tube OD, while nominal 1/4 inch tubing measures about 6.35 mm, so it will not seat on the chuck and will leak or blow off. Use genuine Dia 6 tube, or step to the matching PZ cross size for the tubing you actually run. Tubing should be cut square and pushed fully home to the stop before relying on the grip.
