About the Airtac PZB Cross Threaded Fitting PZB804
The PZB804 is an AirTAC PZB threaded cross: a four-way one-touch junction that lands four Dia 8 mm soft nylon or polyurethane tubes on a single 1/2in PT male thread. Push each tube home and the internal chuck grips it; press the POM release ring on the collar and the tube is freed again. The male thread arrives from the factory with sealant already applied, so it seals straight into a tapped manifold face with no additional tape or paste.
This sits in the resin one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a -20 to +70 C temperature band. The cross body is PBT on a brass stud, with an aluminium-alloy guide, stainless spring gasket and NBR O-rings. Grey is the standard finish; adding a D to the code changes the body colour to black.

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 Is Used
Bottling line reject station
A single 1/2in branch off the reject manifold feeds two blast nozzles and two sensing-air lines at once through this cross, with all four Dia 8 drops released by the same push-to-connect collars during changeover.
Welding fixture clamp manifold
On a robotic welding fixture, the cross splits one 1/2in supply into four Dia 8 lines serving four swing clamps, removing the stack of tees that a three-junction arrangement would otherwise need.
Pick-and-place gantry sub-plate
The 1/2in thread ports into the tapped air sub-plate of a pick-and-place gantry, and the four Dia 8 outlets run vacuum ejectors and jet nozzles distributed to each corner of the travel.
Is the Airtac PZB Cross Threaded Fitting PZB804 the Right Part?
On the 1/2in thread the PZB ladder runs only Dia 8, 10 and 12, so Dia 8 is the smallest bore AirTAC makes for this port size. The next step up in bore is the PZB1004, which keeps the 1/2in thread and moves to Dia 10 tube - about one and a half times the flow area. If the tapped port is actually 3/8in, the PZB803 carries the same Dia 8 tube on the smaller thread instead.
Match the thread to the port you are screwing into, never to the tube, and match the tube OD exactly: the Dia 8 chuck is cut for 8 mm tubing and will not grip 6 mm or 1/4in hose. Where you only need three legs, a PEB or PED tee is the leaner choice; the cross earns its place when four lines genuinely meet at one 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 PZB804 FAQ
It is a one-touch threaded cross for Dia 8 mm soft nylon or polyurethane tubing on a 1/2in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure is 1.5 MPa, the vacuum rating is -750 mmHg (10 Torr), and the temperature range is -20 to +70 C. The body is grey PBT on a brass stud with NBR O-rings.
AirTAC's PZB interface table offers the 1/2in thread only with Dia 8, 10 and 12 mm tube, and the whole PZB range starts at 1/8in thread with Dia 6 - there is no M5 and no Dia 4 cross at all. To reduce the bore at Dia 8, step the port down to 3/8in and use the PZB803 instead.
