About the Airtac PZB Cross Threaded Fitting PZB804D-S
The AirTAC PZB804D-S is a one-touch threaded cross in the black (D-suffix) finish with a SUS304 stainless stud. It screws into a 1/2in PT female port and presents three Dia 8 mm push-in ports at 90 degrees to each other, so a single supply point fans out into four lines without extra tees or couplers. To make a joint you push the soft nylon or polyurethane tube straight home; the internal chuck grips the tube wall and the NBR O-ring seals it, and pressing the release ring lets the tube pull free.
This is the -S stainless variant: AirTAC keeps the body in PBT and upgrades the threaded stud to stainless steel 304 for corrosion resistance in damp or wash-down air. All the ratings are identical to the standard PZB, so there is no re-rating to apply: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service temperature of -20 to +70 C. The 1/2in thread ships with sealant pre-applied, ready to thread into the 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 PZB804D-S Is Used
Bottle-rinse conveyor air take-off
On a bottling or canning line the track is hosed down daily. The SUS304 stud and black PBT body of the PZB804D-S resist the splash zone while feeding three Dia 8 gripper or reject-blower lines from one 1/2in port on the frame manifold.
Plating line actuator header
Acid fumes near electroplating tanks corrode plain brass hardware quickly. Threading this cross into a 1/2in port on the line-side header splits the supply three ways to lift cylinders and rinse nozzles on Dia 8 tubing.
Marine deck valve console
Salt-laden air is brutal on pneumatic junctions on workboat and fishing-vessel decks. A single PZB804D-S at the console port distributes Dia 8 lines to hatch actuators, horn and wiper circuits from one sealed 1/2in connection.
Is the Airtac PZB Cross Threaded Fitting PZB804D-S the Right Part?
On the PZB ladder, Dia 8 is the smallest tube size AirTAC pairs with a 1/2in port - there is no Dia 6 version on this thread, so if your circuit runs Dia 6 tube you step down to a 1/4in or 3/8in port instead (PZB602D-S or PZB603D-S). Stepping up from this SKU gives the PZB1004D-S on Dia 10 tube, which suits longer runs and higher demand legs; note also that a Dia 4 PZB does not exist in the catalogue at any thread. Match the tube exactly: a Dia 8 port will not seal or hold 5/16in or 10 mm tube, even though it looks close. If your layout has one dominant through-flow with a single branch, the PED male run tee is a leaner shape; pick this cross only when three branches genuinely leave one threaded supply point.
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 PZB804D-S FAQ
It is an AirTAC PZB one-touch threaded cross joining Dia 8 mm tube (three ports) to a 1/2in PT male thread, in the black D-suffix finish with a SUS304 stainless stud and PBT body. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C with soft nylon or polyurethane tubing.
No. The stainless variant keeps the stud material to SUS304 and leaves every published figure identical to the standard grey or black PZB: 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C. Note that on PZB-family parts the body itself remains PBT; only the PC and POC straight connectors move to a full stainless 304 body in the -S line.
