About the Airtac PZB Cross Threaded Fitting PZB804D
The PZB804D is an AirTAC PZB threaded cross, a four-way one-touch fitting that turns a single 1/2in PT male port into four independent Dia 8 mm tube outlets, each at 90 degrees to its neighbours. Push the tube home and the stainless spring gasket and chuck grip it against the internal O-ring; press the POM release ring and the tube slides straight out. The body is PBT with a brass stud, and on this SKU the D suffix colours the whole body black rather than the standard grey - useful on dark enclosures where grey fittings stand out.
This is the resin one-touch line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr) and a temperature window of -20 to +70 C. It runs soft nylon or polyurethane tubing. The 1/2in thread arrives with sealant already applied, so it seals directly into a standard PT tapped port. Note that PZB is the largest threaded family in the range and is deliberately not offered in M5 or Dia 4 - those small cross duties go to the PE union tee instead.

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 Is Used
Central distribution on a packaging machine manifold
A single 1/2in PT outlet on the machine's air manifold feeds four Dia 8 runs to sealing jaws, hold-down clamps and the reject pusher in one fitting instead of three tees chained together.
Four-station CNC fixture clamping
The cross splits supply evenly to four Dia 8 clamp cylinders arranged on a square fixture plate, and the black body disappears against the dark anodised fixture base rather than showing scuffs like grey fittings.
Lab automation vacuum manifold
Rated to -750 mmHg (10 Torr), the PZB804D acts as the vacuum distribution point feeding four Dia 8 suction lines to pick-and-place nozzles on an analytical sample handler.
Is the Airtac PZB Cross Threaded Fitting PZB804D the Right Part?
On a 1/2in PT thread, AirTAC makes the PZB cross in Dia 8, Dia 10 and Dia 12 only, so Dia 8 is the smallest tube you can pair with this thread size. The step up is the PZB1004D or PZB1204D, which increase bore and give the cross more air-carrying capacity along each leg. If your actuators are Dia 6 or Dia 4, you cannot step the tube down on a 1/2in thread - instead drop to the PZB802 (Dia 8, 1/4in) or move to a PKD reducer triple branch, which is the proper tool when a supply port feeds smaller branches.
Match the 1/2in PT thread to the actual port before ordering: it suits large manifold faces and valve outlets, not the 1/8in or 1/4in tapped holes common on small cylinders. And remember the golden rule of one-touch fittings - tube OD must match exactly. A Dia 8 chuck will not seal on 5/16in or 10 mm tube, and forcing it in is the classic cause of a slow weep under pressure.
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 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, usable vacuum -750 mmHg (10 Torr), operating temperature -20 to +70 C. It joins four Dia 8 mm soft nylon or polyurethane tubes to one 1/2in PT male thread, in a black PBT body with brass stud and POM release button. This is AirTAC's resin one-touch profile, not the 0.9 MPa / 150 C metal BP line.
AirTAC's PZB interface table starts at Dia 6 on the smallest threads and offers no M5 option at all, and Dia 4 is simply not manufactured in this series. For a small four-way branch, the usual answer is a PE union tee in the right size, or a PGJ plug-in reducer stepping the line down before the cross.
