About the Airtac PZB Cross Threaded Fitting PZB602-S
The PZB602-S is an AirTAC PZB threaded cross, the four-way node of the one-touch resin family: a single 1/4in PT male thread on one side and three Dia 6 mm push-in ports radiating from the same centre. Push each 6 mm soft nylon or polyurethane tube home and the internal chuck grips it under spring load; press the POM release ring square to the port and the tube frees off again. It runs the standard resin spec: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C, with NBR O-rings sealing every chuck. The male thread arrives with sealant already applied, so it screws straight into a PT-tapped port.
The -S suffix changes one thing and one thing only on this part: the threaded stud is SUS304 stainless steel. The cross body stays PBT with an aluminium-alloy guide and POM button, and every pressure, vacuum and temperature figure is identical to the grey standard version. If you need an all-304 body, that is the PC-S straight connector, not the PZB.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PZB602-S Is Used
PCB pick-and-place head
A 1/4in port on the gantry manifold splits to three Dia 6 vacuum lines feeding individual suction cups, so one threaded outlet replaces three tee joints and their leak points.
Bottle-rinse blow-off station
Three Dia 6 blow-off nozzles on a bottling line fed from a single 1/4in PT tapping in the stainless manifold header, keeping the pipework count down in the splash zone.
Lab sample-handler clamp circuit
A laboratory auto-sampler clamping a 6 mm actuator pair plus a purge line from one 1/4in port, where the SUS304 stud shrugs off occasional reagent spills at the thread.
Is the Airtac PZB Cross Threaded Fitting PZB602-S the Right Part?
On the 1/4in rung of the PZB ladder, Dia 6 is the smallest tube made; the row above it is 8 and 10 mm only, so PZB802 is the single step-up and there is no smaller sibling. PZB also has no Dia 4 version at any thread, and no M5 option at all: the threaded cross range starts at 1/8in. If you need Dia 6 on a tighter port, PZB601 is the same cross on 1/8in; PZB603 moves it to 3/8in. Where the node has to pass through a panel wall instead of screwing into one, the PM bulkhead union or PLM bulkhead male elbow is the right shape instead. Whichever you pick, the port must be Dia 6 exactly - this chuck will not seal on 1/4in (6.35 mm) tube.
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 PZB602-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2); vacuum to -750 mmHg (10 Torr); proof pressure 1.5 MPa; temperature -20 to +70 C. It joins Dia 6 mm soft nylon or polyurethane tube to a 1/4in PT male thread, with three Dia 6 push-in outlets. The stud is SUS304; the body is PBT. Ratings are identical to the non-stainless PZB602.
No. On the PZB family the -S suffix swaps only the stud to SUS304 stainless steel. The body remains PBT, and the 1.0 MPa working pressure, 1.5 MPa proof pressure and -20 to +70 C range are unchanged. Never re-rate a stainless one-touch part upward, and at elevated temperatures check the tube's rating first - the tubing, not the fitting, usually gives way first.
