About the Airtac PZB Cross Threaded Fitting PZB1004-S
The PZB1004-S is an AirTAC PZB one-touch threaded cross: a four-way fitting that joins a 1/2in PT male thread to three Dia 10 mm push-in ports, letting one supply line branch into three outlet circuits from a single screw-in point. On a cross, the thread sits on one axis and the three tube ports sit on the other two, so the fitting also acts as a rigid spacer between tube runs.
Connection is genuinely one-touch: push the soft nylon or PU tube straight into a port until it bottoms on the stainless spring gasket and the POM chuck grips the OD; press the release ring to free it. This SKU carries the -S suffix, which means the stud is SUS304 stainless steel while the body stays PBT. Ratings are unchanged from the standard resin line: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum and -20 to +70 C. Threaded ports arrive with sealant applied; no additional tape is needed.

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 PZB1004-S Is Used
Lab automation manifold splitting
On a chemistry analyser or pipetting station, one 1/2in supply off the solenoid bank can be cross-split into three Dia 10 lines feeding separate vacuum ejectors or air knives, all from one threaded port on the frame.
Textile machine air-jet distribution
Looms and spinning frames run banks of small nozzles off a common header; the cross mounts mid-run on the 1/2in PT stud and feeds three 10 mm branch lines to nozzle blocks on either side and below.
Control cabinet pneumatic feedthrough
With the stud passed through a panel cut-out, the cross turns one bulkhead penetration into three push-in take-offs for inside-the-door cylinders and air blast nozzles, keeping the wet side outside the enclosure.
Is the Airtac PZB Cross Threaded Fitting PZB1004-S the Right Part?
On the 1/2in PT row of the PZB ladder the supported tube sizes are Dia 8, 10 and 12, so the PZB804 steps down to 8 mm lines and the PZB1204 steps up to 12 mm. Dropping to Dia 8 saves panel space and suits lighter actuator loads; going to Dia 12 lowers air velocity on long runs or high-consumption headers. Dia 10 in the same thread is also offered as PZB1003 if your port is 3/8in instead of 1/2in.
Tube OD must match exactly: a Dia 10 port will not seal on 3/8in (10 mm is close but the chuck is cut for metric wall thickness and tolerance). A PZB cross is the right shape when you need four connections meeting at one point without a fabricated manifold block; if you only need two tube legs, a PE union tee is the smaller answer.
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 PZB1004-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr), operating temperature -20 to +70 C. This SKU joins Dia 10 mm soft nylon or polyurethane tube to a 1/2in PT male thread. The -S suffix adds a SUS304 stainless stud; every pressure, vacuum and temperature figure is identical to the grey standard version.
On the PZB family the -S option makes the threaded stud SUS304 stainless steel; the cross body remains PBT with POM chucks, an aluminium guide and an NBR seal. It does not re-rate the fitting, so use the standard 0-1.0 MPa / 70 C figures when sizing. Choose it where a corroded stud would seize in a housing - washable machine frames or coastal plant - and match the tube to the temperature limit, since standard PU and nylon tubing, not the fitting, sets the ceiling near 70 C.
