About the Airtac PZB Cross Threaded Fitting PZB601
The PZB601 is an AirTAC PZB threaded cross, a four-way node that screws into a 1/8 in PT female port and lets three Dia 6 mm tubes branch off the fourth leg at 90 degrees to each other. Push each tube into its chuck until it bottoms and the stainless spring gasket grips it; press the release ring to free it. It belongs to the resin and brass one-touch line, so it is rated 0-1.0 MPa (0-10 kgf/cm2), handles -750 mmHg (10 Torr) vacuum, and works from -20 to +70 C on soft nylon or polyurethane tubing.
Two catalogue facts worth knowing before you order: PZB is one of the few prefixes with no M5 option at all, and Dia 4 mm is not offered on this series either, so Dia 6 is genuinely the smallest cross in the family. The 1/8 in thread arrives pre-coated with sealant and pairs only with Dia 6 and Dia 8 tubes on this prefix. The body is PBT on a brass threaded stud, with a POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring; grey is standard and a D suffix orders the black version.

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 PZB Cross Threaded Fitting PZB601 Is Used
Modular fixture manifolds
On a weld-and-assemble fixture with pneumatic clamps on three faces, a PZB601 at the entry block splits the 1/8 in supply into three Dia 6 mm runs without stacking unions in the cramped fixture frame.
Pick-and-place header plates
Compact pick-and-place modules often need suction lines, a blow-off and a signal-gauge tap at one point; the four legs of this cross feed all three Dia 6 mm circuits from a single 1/8 in port.
Bottling line reject stations
At a bottle-reject puff station, a PZB601 mounted on the frame splits the supply between the reject nozzle, the gate cylinder and a sensor purge line, all in Dia 6 mm nylon tube.
Is the Airtac PZB Cross Threaded Fitting PZB601 the Right Part?
PZB601 sits at the bottom of the cross ladder: there is no Dia 4 PZB below it, so if you step down you are really changing shape - a PYB branch Y (PYB601) covers three-way splitting at the same 6 mm and 1/8 in size. Stepping up in bore gives the PZB801, and if 1/8 in is too small for the flow your circuit needs at a shared node, the PZB602 keeps the Dia 6 tube but moves to a 1/4 in PT thread. Remember the tube must match exactly: a Dia 6 chuck will not seal on 1/4 in (6.35 mm) imperial hose, so re-terminate the line rather than forcing it.
Choose a cross over a tee only when you truly need four connections in one body - each extra leg adds a potential leak path and a push-fit to maintain. If your fourth connection is a plug instead, a PED male run tee with a PP plug in the spare port does the same job with more future flexibility.
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 PZB Cross Threaded Fitting PZB601 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. It is a threaded cross for Dia 6 mm soft nylon or polyurethane tube with a 1/8 in PT male thread, supplied with sealant on the thread. These are the resin and brass one-touch ratings; the higher-temperature 150 C figures apply only to the separate BPC metal family.
No on both counts. AirTAC makes no M5 version of the PZB series, and Dia 4 mm is not offered on this prefix, so Dia 6 mm is the smallest cross available. For an M5 four-way arrangement you would have to build it from other prefixes, for example a PEB601-M5 male branch tee plus a PE601 union tee downstream.
