About the Airtac PZB Cross Threaded Fitting PZB603
The PZB603 is an AirTAC one-touch threaded cross: a four-way node with one male 3/8in PT thread on its inlet leg and three Dia 6mm push-in ports on the remaining legs. Instead of chaining tees and connectors, you thread one part into a port or manifold and branch three tube lines straight off it. Each push-in port works the same way: push the tube fully home and the internal chuck grips the OD, then press the release ring to let it go.
This is the resin/brass profile, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The release button and chuck are POM, the threaded body is PBT on a brass stud, with a stainless spring gasket and NBR O-ring doing the tube seal. The 3/8in thread arrives with sealant already applied, so it is ready to screw straight into a PT port.

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 PZB603 Is Used
Bottling monobloc clamp circuit
A single 3/8in manifold port on a rotary filler can feed three Dia 6 clamp or guide-cylinder lines at once, replacing a stack of elbows and unions inside a crowded guard.
Screen-printing carousel stations
Printing carousels run repeated identical pneumatic stations. A PZB603 at each station's supply point splits one threaded feed into three Dia 6 squeegee or flood-bar lines without extra threaded joints.
Dispensing manifold in lab automation
Compact dispensing cells often need one regulated supply split to three small Dia 6 actuator or pump lines; the cross does it in one screw-in part and frees the rest of the back panel.
Is the Airtac PZB Cross Threaded Fitting PZB603 the Right Part?
Within the PZB ladder, Dia 6 is the smallest tube this cross is made in - there is no Dia 4 version of the threaded cross, so there is nothing to step down to. Stepping up one size gives the PZB803, which takes Dia 8 tube and the same 3/8in thread; that buys you a larger bore for circuits where the Dia 6 lines feed anything flow-hungry. On the thread side, the PZB602 gives you Dia 6 on a 1/4in port instead, and note that a 1/2in threaded cross only exists from Dia 8 upward.
Whatever you choose, the tube must match the port exactly: a Dia 6 port will not securely hold 1/4in (6.35mm) tube even though the difference looks trivial. If you only need two branch lines rather than three, a PEB or PED branch tee is the leaner part; keep the cross for genuine four-way splits.
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 PZB603 FAQ
It is an AirTAC PZB one-touch threaded cross with three Dia 6mm push-in tube ports and one male 3/8in PT thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum rating -750 mmHg, proof pressure 1.5 MPa, and operating temperature -20 to +70 C. It is intended for soft nylon or polyurethane tubing.
Not directly. In the PZB range the 1/2in thread is only produced from Dia 8 tube upward, so a Dia 6 body on a 1/2in thread does not exist in the catalogue. Use the PZB804 with Dia 8 tube, step to the PZB602 on a 1/4in port, or fit a reducing bush in the port first - the tube size must match the push-in port exactly either way.
