About the Airtac PZG Cross Reducing Fitting PZG10-8D
The PZG10-8D is an AirTAC different diameter cross, a four-port push-in union that lets Dia 10 tubing and Dia 8 tubing meet at a single node. Instead of splicing two tees together, you push each tube straight into its port: internal stainless spring gaskets and chuck jaws grip the tube wall on insertion, and pressing the POM release ring frees it again for rework.
This belongs to the resin and brass one-touch family, not the metal BP line, so it carries the standard 0 to 1.0 MPa (0-10 kgf/cm2) working pressure, 1.5 MPa proof pressure, -750 mmHg (10 Torr) vacuum rating and a -20 to +70 C window with soft nylon or polyurethane tubing. The D suffix gives the PBT body a black finish across the whole part, which is worth knowing because on the PC and POC connectors a D only changes the release button.

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 PZG Cross Reducing Fitting PZG10-8D Is Used
Palletizing gripper air distribution
A 10 mm supply line reaching the top of a palletizer cross-member splits through this reducing cross into two 8 mm drops, each feeding a suction-cup ejector circuit on the end-of-arm tooling.
Four-way drops behind a machine control column
Mounted inside the column of a packaging machine, the cross lets one 10 mm riser serve a 12 mm pass-through on one axis and 8 mm branch lines to directional valves on the other, cutting hose-run count.
Textile machine compressed-air trimming ring
Around the perimeter frame of a weaving or knitting machine, the cross steps the main 10 mm blowing line down to 8 mm nozzles at each quadrant, and the black body blends with the machine's painted steelwork.
Is the Airtac PZG Cross Reducing Fitting PZG10-8D the Right Part?
This code sits mid-ladder. Step down to the PZG8-6 when the main run is an 8 mm line feeding 6 mm drops, or step up to the PZG12-10 if your trunk is 12 mm and you are branching to 10 mm circuits - each step changes the bore and therefore the air capacity the cross can pass, so match it to the tubing you actually run. Note the directions: the reducer pair is ordered larger-first, never the reverse.
Every port is size-specific, and tube OD must match exactly. A Dia 8 port will not seal on 5/16 inch or 1/4 inch tube no matter how hard you push it, and forcing it is the most common cause of a weeping joint on site. If your circuit branches to two different smaller sizes rather than one, two PZG unions in series or a PGJ reducer paired with a plain PZ cross may fit better than forcing one part number to do everything.
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 PZG Cross Reducing Fitting PZG10-8D FAQ
It is a different diameter cross joining Dia 10 tubing to Dia 8 tubing, with no threaded port. Working pressure is 0 to 1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the temperature range is -20 to +70 C with soft nylon or polyurethane tubing. It is a resin-and-brass one-touch part with a black (D suffix) PBT body, POM release rings, aluminium-alloy guides, stainless spring gaskets and NBR O-rings.
On the PZG union series the D changes the body finish to black; the pressure, vacuum and temperature ratings and the internal materials stay identical to the grey standard version. This differs from the PC and POC connectors, where a D suffix only recolours the release button. Fit and function are otherwise the same, so you can choose purely on appearance or on wash-down contrast requirements.
