About the Airtac PZB Cross Threaded Fitting PZB1003
The PZB1003 is an AirTAC PZB threaded cross, a four-way node that puts a 3/8in PT male thread on one leg and three Dia 10 mm one-touch ports on the other three. Push each soft nylon or polyurethane tube home and the stainless spring gasket and chuck grip it instantly; press the POM release ring and the tube slides back out for rework. The 3/8in stud arrives with sealant already on the thread, so it seals straight into a PT tapped port.
This is the resin and brass one-touch profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C service. The body is PBT over a brass stud, with an aluminium-alloy guide, stainless spring gasket and NBR O-ring. Note that PZB never comes in M5 thread or Dia 4 tube, so this 3/8in x Dia 10 size sits firmly in the larger half of the ladder.

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 PZB1003 Is Used
Palletiser grip manifold
Mount the 3/8in stud in a manifold plate beside a palletiser vacuum generator and branch three Dia 10 lines to suction cups and blow-off nozzles, replacing three separate tees with one node.
Bottling line actuator cluster
Feed a group of small pneumatic cylinders on a bottling line gate from a single 3/8in PT drop, with equal Dia 10 legs to each cylinder port for balanced extend and retract timing.
Lab purge distribution
On a purge or inert-gas skid, tap the 3/8in thread into the supply header and run three Dia 10 polyurethane legs to individual enclosure vents, each releasable without disturbing the others.
Is the Airtac PZB Cross Threaded Fitting PZB1003 the Right Part?
On the 3/8in thread row, PZB goes down to Dia 8 (PZB803) and up to Dia 12 (PZB1203); stepping to Dia 12 gains bore for longer or hungrier circuits, while Dia 8 saves panel space on lighter branches. If your tube is Dia 10 but the port is smaller or larger, PZB1002 (1/4in) and PZB1004 (1/2in) exist at the same tube size, so you can change the thread without changing the tubing run.
A cross is the right answer only when one supply must genuinely feed three outlets from one point. If the run is a simple step down in bore rather than a three-way split, a PKD male reducer triple branch or a PG different-diameter union will be tidier. Always match tube OD exactly: a Dia 10 port will not seal on 3/8in or 12 mm tube, however close it looks.
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 PZB1003 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It accepts Dia 10 mm soft nylon or polyurethane tube on three ports and has a 3/8in PT male thread on the fourth. The thread ships pre-coated with sealant.
AirTAC simply does not make those combinations. The PZB threaded cross ladder starts at 1/8in PT with Dia 6 and Dia 8 tube, and Dia 4 is excluded across the whole series. For miniature four-way work you would need a different family; for this SKU the supported threads at Dia 10 are 1/4in, 3/8in and 1/2in.
