About the Airtac PZB Cross Threaded Fitting PZB1204D
The PZB1204D is an AirTAC PZB threaded cross: one 1/2in PT male thread on the inlet leg and three Dia 12mm one-touch tube ports at 90 degrees around the body. Push the tube home and the internal chuck grips it under the stainless spring gasket; press the POM release ring and the tube slides straight back out. It turns one threaded supply into three tube branches without any additional junction fittings.
This is the resin one-touch line, rated 0-1.0 MPa (0-10 kgf/cm2) working, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure, and -20 to +70 C with soft nylon or polyurethane tube. The body is PBT on a brass stud and the threaded port arrives with sealant already applied, so no PTFE tape is needed on assembly. Because this is the D suffix on the PZB series, the entire body is moulded black - on PC and POC connectors the D only changes the release button, but here it colours the whole fitting.

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 PZB1204D Is Used
Palletiser wrist manifold
On a palletising robot arm, one 1/2in feed enters the cross and three Dia 12mm lines run out to twin-stream grippers and a side clamp, all routed inside the arm dressing without extra tees.
Rotary bottling lifters
At each filling-head station on a rotary bottling machine, the cross mounted beside the lift cylinder splits the supply into the lift, the purge and the nozzle-vent lines in one fitting.
Weld-cell clamp distribution
A 1/2in branch off the header in an automotive weld cell feeds three Dia 12mm swing-clamp cylinders from a single cross, shortening the manifold run on the fixture baseplate.
Is the Airtac PZB Cross Threaded Fitting PZB1204D the Right Part?
Dia 12 is the top of the PZB ladder at 1/2in thread - AirTAC publishes nothing larger in this series, so the useful step is downwards: PZB1004D carries Dia 10mm tube on the same 1/2in thread when your actuators are smaller, and PZB1203D keeps the Dia 12 ports but drops the thread to 3/8in PT for a smaller tapped port. Match the thread to the port drilling first, then size the tube.
Remember the tube must be exactly Dia 12mm OD. A one-touch chuck sized for 12mm will not seal on 10mm tube, and it will not hold nominal 1/2in hose either - the OD is close but the wall and grip geometry are wrong. If you need a cross with no threaded leg at all, that is the PZ union cross instead.
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 PZB1204D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. It joins Dia 12mm soft nylon or polyurethane tube to a 1/2in PT male thread, with three further Dia 12mm one-touch tube ports. The body is black PBT on a brass stud; PT is the thread standard for the whole series.
Mechanically it is identical to the grey PZB1204 - same PBT body, same 1.0 MPa rating, same dimensions and same interface ladder. The difference is scope: on PC and POC straight connectors the D suffix recolours only the release button, while on the PZB series it colours the whole body, which is why this version is chosen to match black machine housings and dark cabinet interiors.
