About the Airtac PZB Cross Threaded Fitting PZB1003-S
The PZB1003-S is AirTAC's threaded cross from the one-touch fitting range, built around Dia 10 mm tubing and a 3/8 inch PT male thread. Where a tee joins three lines, this cross joins four from a single hub: one threaded stud plus three push-in ports, so a branch point that would normally need two tees and a spacer collapses into one fitting with fewer joints and fewer potential leak paths. Installation is the standard one-touch action - push the soft nylon or polyurethane tube fully home and the internal chuck grips it under spring load; press the POM release ring to free it.
This -S variant carries a SUS304 stainless steel stud on the threaded end, chosen for corrosion resistance in washdown, humid or mildly corrosive air service. Note the construction honestly: the cross body itself remains PBT, with only the stud upgraded to stainless 304. Pressure and temperature ratings are identical to the standard resin line - 0 to 1.0 MPa working, 1.5 MPa proof, -20 to +70 C - because stainless changes the material story, not the spec sheet. The 3/8in stud arrives with thread sealant applied and mounts into any PT-tapped port.

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 PZB1003-S Is Used
Packaging machine header split
On a carton-sealing line, a single 3/8in PT drop from the FRL manifold feeds three Dia 10 mm cylinder circuits at once. The PZB1003-S makes that four-way split at the machine frame in one fitting instead of stacking two tees.
Washdown fixture on a food-grade conveyor
Clamp cylinders around a rinse-zone transfer plate all need supply from one point where splashes hit bare metal. The SUS304 stud resists the washdown environment while the PBT body keeps the standard 1.0 MPa rating.
Textile machine air distribution
Loom and knitting frames run dozens of short pneumatic jets and actuators packed behind the needle bed. A threaded cross lets one PT port feed three Dia 10 mm jet lines without extra elbows crowding the frame.
Is the Airtac PZB Cross Threaded Fitting PZB1003-S the Right Part?
Step down to PZB803 for a Dia 8 line or up to PZB1203 for Dia 12 - both exist on the same 3/8in thread, and the cross grows in every dimension while flow capacity follows the tube bore. If your port is 1/4in or 1/2in PT instead, the same Dia 10 cross is sold as PZB1002 and PZB1004, so you can match the thread without changing tube size. Two PZB facts worth knowing before you order: the series is never offered in Dia 4, and it has no M5 option at all - the smallest thread is 1/8in and that only carries Dia 6 or Dia 8 tube.
A cross is the right answer when four lines genuinely meet at one point, such as a supply feed splitting to three actuators around a fixture. If your fourth leg is really a 90 degree turn rather than a branch, a PL male elbow or PEB branch tee will be cheaper and easier to route. And as with every one-touch part here, tube OD must match exactly: this fitting holds Dia 10 mm tube only and will not seal on 3/8in imperial hose.
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 PZB1003-S FAQ
It is a threaded cross for Dia 10 mm tube with a 3/8in PT male stud. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum rating is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tubing. The stud is SUS304 stainless steel; the cross body is PBT. Ratings are identical to the standard grey PZB1003.
No. On the PZB family, the -S suffix upgrades only the threaded stud to SUS304 stainless steel; the cross body stays PBT with the same internal chuck and NBR seal as the standard part. This matters for corrosion planning: the stud and thread interface are protected, so spec the -S where the fitting screws into exposed or washdown-facing hardware, not because the whole part is stainless. The published pressure, vacuum and temperature figures do not change with the -S option.
