About the Airtac PZB Cross Threaded Fitting PZB1204D-S
The PZB1204D-S is an AirTAC threaded cross from the resin one-touch range: a single 1/2in PT male thread on one leg and three push-in ports for Dia 12 mm soft nylon or polyurethane tube. Push the tube home and the internal chuck grips it against the stainless spring gasket; press the POM release ring and it frees again for rework. This is the D (black) body colour, and because the code carries the -S suffix the male stud is SUS304 while the shaped body remains engineering-grade PBT - it is not a solid stainless part.
Spec profile is the standard resin line, identical to the grey version: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The stud arrives with thread sealant applied, ready to wind into a PT port. Note that PZB is AirTAC's rarest one-touch shape and starts at Dia 6 - there is no M5 thread and no Dia 4 variant anywhere in the series, so a cross is always a deliberate, larger-bore choice.

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 PZB1204D-S Is Used
CNC chip-blow-off manifold
On a machining centre slide, the 1/2in stud screws into the main blow-off feed and three Dia 12 drops run to individual air nozzles that clear chips from the spindle nose, ways and tool changer pocket - one port, three jets, no stack of tees.
Palletizing robot vacuum header
A layer-picking head for cartons uses the cross as the junction where the vacuum feed meets three Dia 12 lines, each serving a row of suction cups - the 12 mm bore keeps line velocity low on high-flow vacuum recovery.
Textile machine air distribution
On a weaving or stenter line where stop-motion jets and thread guides all need clean dry air, the black PBT cross sits on a 1/2in riser and branches Dia 12 tube out to three station drops along the machine frame.
Is the Airtac PZB Cross Threaded Fitting PZB1204D-S the Right Part?
Step down in thread to PZB1203 (Dia 12 on 3/8in PT) if your port is smaller; there is nothing above 1/2in in this catalogue, so PZB1204 is the top of the thread ladder for Dia 12. In tube terms the neighbour below on the same 1/2in thread is PZB1004 at Dia 10 - dropping a size eases the grab on the tube and suits lighter branch lines, while Dia 12 carries the most generous bore this shape offers. If you only need one branch plus a feed, a PEB male branch tee is the simpler part; take the cross only when three tube drops leave one threaded leg.
Tube OD must match exactly: a Dia 12 (12 mm) socket will not grip 1/2in imperial tube, which measures 12.7 mm and is only 0.7 mm too big to seal. Also remember the -S rating discipline here - the SUS304 stud buys corrosion resistance at the thread, nothing else changes; pressure, vacuum and temperature figures are the same as the grey PZB1204.
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 PZB1204D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. This SKU is the threaded cross with three push-in ports for Dia 12 mm tube on a 1/2in PT male thread, in the black D body colour with a SUS304 stud. Tubing must be soft nylon or polyurethane.
No. On the PZB family the -S means the male stud is SUS304 for corrosion resistance at the port interface; the cross body stays PBT, which here is black because of the D suffix. Push-in internals - POM release ring, aluminium guide, stainless spring gasket and NBR seal - are unchanged, and the ratings are identical to the standard grey PZB1204.
