About the Airtac PZB Cross Threaded Fitting PZB801-S
The PZB801-S is an AirTAC one-touch threaded cross: a single 1/8in PT male port in the centre that splits into four Dia 8 mm tube outlets at 90 degrees to each other. Push each tube home and the internal chuck grips it; press the release ring and the tube frees again. AirTAC lists no M5 or Dia 4 version of the PZB, so 1/8in with Dia 6 or Dia 8 is the smallest cross in the series.
The -S suffix makes this the SUS304 variant: the centre stud is stainless steel 304 while the body stays glass-reinforced PBT with a POM release button and NBR seal. Every published rating carries over unchanged from the grey PZB801 - working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa and -20 to +70 C - so you buy the -S for corrosion resistance at the thread interface, never for a higher rating.

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 PZB801-S Is Used
Valve manifold four-way split
Mounted directly on the 1/8in outlet of a solenoid valve manifold on a packaging machine, this cross feeds four Dia 8 runs to individual cylinder ports from a single connection point.
Plating line wash zone
On an electroplating or surface-treatment line where splash and acidic wash-down attack plated brass fittings, the SUS304 stud at the port resists corrosion while the PBT body sheds chemicals.
Conveyor air-knife distribution
A conveyorised food-packaging line uses the cross to divide one Dia 8 supply into four short legs serving small air-blast nozzles that clear crumbs from a belt before sealing.
Is the Airtac PZB Cross Threaded Fitting PZB801-S the Right Part?
Your two nearest steps on the PZB ladder both exist. Step down to the PZB601 and you keep the 1/8in thread but feed Dia 6 tube - a smaller bore per leg, so expect more pressure drop along each run at the same flow demand. Step up to the PZB802 and you keep the Dia 8 tube but move the centre port to 1/4in PT, which suits larger valve outlets and gives more metal in the thread for higher tightening loads. With a 1/8in thread, Dia 8 is the largest tube PZB offers; going to Dia 10 or Dia 12 requires stepping the thread up to 3/8in or 1/2in.
Match the centre thread to the port you actually have - an 1/8in PT port on a solenoid valve or manifold takes this cross directly, since the threads arrive pre-coated with sealant. If you only need to split air three ways, a PEB or PED tee is the leaner part; choose this cross only when four branches leave one point. Tube OD must match exactly: a Dia 8 chuck will not seal on 5/16in or Dia 6 tube.
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 PZB801-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum capability to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature range of -20 to +70 C. This SKU is a threaded cross with four Dia 8 mm tube outlets and a 1/8in PT male centre thread, with a SUS304 stud and PBT body. These figures are identical to the standard grey PZB801; the stainless option does not re-rate the part.
No. One-touch chucks grip one tube OD only, so the Dia 8 legs accept exactly Dia 8 mm soft nylon or polyurethane tube - 5/16in or Dia 6 tube will not seal or retain. If your circuit runs Dia 6, order the PZB601 instead; if you need Dia 10 or Dia 12 branches, the PZB ladder requires stepping up to a 3/8in or 1/2in centre thread.
