About the Airtac PZB Cross Threaded Fitting PZB804-S
The AirTAC PZB804-S is a threaded cross from the one-touch PZB family: a 1/2in PT male stud feeding a four-way body whose three push-in legs each grip 8mm soft nylon or polyurethane tube. Push the tube home and the internal chuck grips it; press the POM release ring and the spring gasket frees it. With the -S suffix the stud itself is SUS304, so the port thread is stainless 304 while the cross body remains PBT.
Ratings follow the standard resin profile, not a separate stainless spec: 0-1.0 MPa working, -750 mmHg vacuum, 1.5 MPa proof, -20 to +70 C. AirTAC ships threaded P-series parts with sealant already applied to the thread, so the stud seals straight into a PT tapped port. Note that PZB has no M5 or Dia 4 variants, and Dia 8 is the smallest tube the 1/2in thread is offered with.

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 PZB804-S Is Used
Cartoning machine base drop
One 1/2in PT supply at the base of a cartoning machine splits into three 8mm drops feeding gripper cylinders and a vacuum ejector, replacing a tee plus an extra elbow in the frame cavity.
Fish-plant wash-down air ring
On a fish-processing or poultry plant air ring hosed down daily with brine and caustic rinse, the SUS304 stud resists pitting at the port where a plated brass thread would corrode first.
Bottling conveyor cluster feed
A single riser behind a bottling conveyor feeds three 8mm take-offs to reject pushers and flap diverters from one cross, holding the 1/2in supply right up to the last split.
Is the Airtac PZB Cross Threaded Fitting PZB804-S the Right Part?
Stepping in tube size: PZB602 drops to Dia 6 but pairs it with a 1/4in thread, while PZB1004 upsizes to Dia 10 on the same 1/2in stud. On a 1/2in thread the ladder is Dia 8, 10, 12, so Dia 8 is the floor at this port size. On the thread side, PZB803 keeps the same Dia 8 tube on a 3/8in port, and 1/2in is the largest thread AirTAC makes in this series. Match the tube OD exactly - the Dia 8 chuck will not hold Dia 6 or Dia 10 tube.
Choose the cross shape when one supply point must feed three tube drops; it saves the tee-plus-elbow stack that a plain branch fitting would need, and keeps the supply at full 1/2in bore up to the split.
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 PZB804-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. This SKU is the Dia 8 tube cross with a 1/2in PT male thread and a SUS304 stud; the -S variant carries exactly the same ratings and dimensions as the standard grey part.
No. In the PZB family the -S suffix makes the stud SUS304, so the port thread is stainless 304, while the cross body stays PBT with POM release rings, a stainless spring gasket and an NBR O-ring. AirTAC publishes no separate pressure, temperature or dimensional spec for the stainless variant - only the stud material changes.
