About the Airtac PZB Cross Threaded Fitting PZB1203D-S
The AirTAC PZB1203D-S is a threaded cross in the PZB family: one 3/8 in PT male thread and three one-touch ports that all accept Dia 12 mm outer diameter tubing. Push each tube home and the internal chuck grips it for a pressure-tight joint; press the release ring and the tube slides straight back out. No tools, no clamps, no re-taping.
This is the resin-line spec profile: 0 to 1.0 MPa working pressure, 1.5 MPa proof pressure, -750 mmHg vacuum capability, and -20 to +70 C service. The -S suffix adds a SUS304 stainless stud while the body stays PBT in black, so the corrosion-resistant thread is what faces the outside world. Note that PZB never came in M5 - the 3/8 in thread here is two full steps up from the family's smallest 1/8 in option.

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 PZB1203D-S Is Used
Bottling line air drop junction
On a rinse-and-fill conveyor, a single 3/8 in port under the frame needs to feed two 12 mm guides and a reject-blower line. A cross does it in one fitting instead of three tees, keeping the drop short and the leak count low.
Plating line jig actuation
Electroplating jigs see acidic mist and wash-downs, and a plain brass stud pitted by that environment can seize in its port. The SUS304 stud on the PZB1203D-S shrugs off the atmosphere while the PBT body stays inert.
Textile machine four-way split
A knitting machine's main 12 mm air line branches to three suction nozzles plus the threaded inlet from the machine's valve block. The cross in the line trunk keeps all four legs at equal bore with no restrictors.
Is the Airtac PZB Cross Threaded Fitting PZB1203D-S the Right Part?
PZB on a 3/8 in thread is made in Dia 6, 8, 10 and 12, so Dia 10 (PZB1003) is the step down - same thread, one bore smaller, for lighter lines or where you want to hold flow velocity up. Dia 12 is the largest tube on a 3/8 in PZB; if the port itself is bigger, the step up is a thread change to 1/2 in (PZB1204), which also runs 8 to 12. Match the PT male thread to the port size you actually have, and remember the one-touch port holds only Dia 12 tube - a nominal 1/2 in hose will not seal in it. If you need the cross to pass through a panel wall instead of hanging on a port, the PM bulkhead family is the shape for that job.
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 PZB1203D-S FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), temperature -20 to +70 C. The part joins Dia 12 mm outer diameter soft nylon or polyurethane tube on all three one-touch ports and has a 3/8 in PT male thread. The -S suffix makes the stud SUS304 stainless; pressure, vacuum and temperature ratings are identical to the standard grey or black PZB1203.
No. On the PZB family the -S variant keeps a PBT body (black, in this D-colour code) and upgrades only the threaded stud to SUS304 stainless steel. That is the right choice when it is the thread and stud that sit in a corrosive or exposed position. The dimensions, the one-touch mechanism and every pressure and temperature figure match the standard version exactly, so it is a straight swap.
