About the Airtac PZB Cross Threaded Fitting PZB601D
The AirTAC PZB601D is a one-touch threaded cross: a single 1/8in PT male port that splits air into four legs, each gripping a Dia 6 mm tube. Push the tube home and the internal chuck claws it tight; press the POM release ring and it slides free. The brass stud arrives with sealant already on the thread, so it winds straight into the port and seals without extra tape or compound.
This sits on AirTAC's resin one-touch spec: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C with soft nylon or polyurethane tubing. The D suffix makes the whole body black rather than grey, which is useful on machines where colour-coded air circuits matter - on this series the D changes the body itself, not just the button. Body is PBT with a brass stud and NBR seals. Note the PZB ladder starts here: there is no M5 version and no Dia 4 cross anywhere in the 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 PZB Cross Threaded Fitting PZB601D Is Used
Vacuum former distribution head
A four-way split at the 1/8in port feeds hold-down cups around a vacuum-forming platen, all in 6 mm polyurethane line.
Rotary indexing table circuits
Crosses at each station of a dial-table fixture supply clamp and unclamp legs from one centrally threaded take-off.
Control cabinet pilot network
A black PZB601D behind a panel routes one air feed to two valve islands and two pressure switches on matching 6 mm tubing.
Is the Airtac PZB Cross Threaded Fitting PZB601D the Right Part?
Two ways to step from this SKU. On tube bore, the only other 1/8in cross is the PZB801 (Dia 8) - there is no Dia 4 PZB, so if the branch feeds an actuator below 6 mm you need a different prefix or a reducer downstream. On thread, the PZB602 (Dia 6, 1/4in) is the next rung up; 1/8in only supports Dia 6 and 8, while 1/4in opens Dia 6, 8 and 10. AirTAC's thread standard here is PT throughout, and this catalogue publishes no G or NPT ordering codes.
A cross earns its place when two tees would need a welded or stacked manifold. Check the tube OD first: a Dia 6 fitting will not seal on 1/4in (6.35 mm) tube, even though the numbers look close. Capacity scales with bore, so read flow off AirTAC's characteristic curves for the tube size, not the fitting.
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 PZB601D FAQ
Dia 6 mm tube on all four legs, 1/8in PT male thread. Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum down to -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. Soft nylon or polyurethane tubing only. Resin one-touch construction: PBT body, brass stud, POM release ring, NBR seals. The D suffix denotes the black body colour.
No. All four chuck ends are Dia 6 mm only and will not seal on 6.35 mm (1/4in) imperial tube. Every leg must be the same 6 mm OD soft nylon or polyurethane. If a leg needs a smaller bore, put a PG reducer union or a PGJ plug-in reducer inline rather than forcing a mismatched tube into the chuck.
