About the Airtac PZB Cross Threaded Fitting PZB1204-S
The PZB1204-S is an AirTAC one-touch threaded cross: a single 1/2in PT male port that splits the supply into three Dia 12 mm tube outlets at 90 degrees to each other. Push each tube home and the internal chuck grips it; press the release ring and it lets go. The trailing -S means this is the SUS304 variant, and on the PZB family that means the threaded stud is stainless steel 304 while the body stays PBT - a sensible pick when the stud sits in a wash-down zone or a damp plant where a bare brass stud would stain or corrode.
This is a resin-profile part, so it runs 0-1.0 MPa working pressure, holds vacuum to -750 mmHg, proofs at 1.5 MPa and handles -20 to +70 C. Threads arrive with sealant pre-applied, so it threads straight into a PT port without extra tape. Two catalogue facts worth knowing before you order: PZB is never offered in M5 or Dia 4, so this is a mid-to-large-air part by design, and Dia 12 on a 1/2in thread is the very top of the PZB ladder - there is no larger tube above it.

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 PZB1204-S Is Used
Bottling line distribution block
A 1/2in PT branch off the filter-regulator feeds three Dia 12 lines in one fitting, running star wheels and reject pushers on a filling machine without a tangle of tees.
Palletiser gripper manifold
The cross splits one supply into three Dia 12 drop lines to clamp and support cylinders on a robotic palletiser head, keeping the plumbing symmetric around the tool plate.
Valve-station supply take-off
Mounted on a 1/2in PT outlet of a directional valve manifold on a rubber press, it fans air out to three Dia 12 actuator circuits from a single port.
Is the Airtac PZB Cross Threaded Fitting PZB1204-S the Right Part?
Stepping down one tube size takes you to PZB1004-S (Dia 10, same 1/2in thread) - same port, a bore one step smaller feeding lighter lines. There is no step up: Dia 12 is the largest tube PZB makes on this thread, so if your actuator takes anything bigger, this family is not it. On the thread side, PZB1203-S gives you the same Dia 12 tube on a 3/8in port if your manifold is drilled smaller. Remember the tube must match exactly: this fitting holds Dia 12 mm soft nylon or polyurethane, not 1/2in hose - those are different measures entirely.
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 PZB1204-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 12 mm soft nylon or polyurethane tube to a 1/2in PT male thread. It is the SUS304 variant: stainless 304 stud, PBT body, POM release button and chuck, NBR O-ring. Threads ship with sealant pre-applied.
On the PZB family it swaps the brass threaded stud for SUS304 stainless steel 304, which resists corrosion in wash-down areas, damp plants and near coolants. The body remains PBT and the shape and dimensions are identical to the standard part. Pressure, vacuum and temperature ratings do not change at all with the -S, so you can substitute it 1:1 for the plain PZB1204.
