The AirTAC Airtac PZB Cross Threaded Fitting PZB1002D-S is a genuine threaded cross for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PZB1002D-S is an AirTAC PZB threaded cross in the SUS304-stud variant: a four-way one-touch junction with a 1/4 in PT male thread on one leg and three push-in sockets for Dia 10 mm soft nylon or polyurethane tube. Push each tube home and the internal chuck grips it; press the POM release ring and the chuck lets go. Worth knowing before you shortlist: the PZB ladder has no M5 and no Dia 4 entry at all - the family starts at 1/8 in with Dia 6 tube, so this cross already sits in the upper half of the range.
It runs the standard resin one-touch profile: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. These are the resin figures, not the 0.9 MPa / 150 C metal BP line. The trailing -S fits a SUS304 stud where the fitting screws into the port; the cross body itself stays PBT, with POM release rings, an aluminium-alloy guide, a stainless spring gasket and NBR O-rings. The D in the code marks the black-body version of the standard part.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

Splitting a Dia 10 supply three ways at a chain-lubrication and hold-down station on a meat-processing washdown conveyor, where the SUS304 stud stands up to daily caustic spray at the threaded port.
A 1/4 in PT feed from an acid-fume-exposed plating line riser branching to rinse-nozzle tubes, agitator cylinders and a DI-water ejector, with corrosion resistance concentrated at the metal-to-port interface.
One machine riser thread feeding two vacuum-ejector lines and a tube run to the corner-guide cylinder on a case palletizer, replacing three separate tees with a single compact four-way body.
On the PZB interface table a 1/4 in thread carries Dia 6, 8 and 10 tube, so Dia 10 is the largest bore you can run on a 1/4 in cross. Step down to PZB802 for Dia 8 if the branch feeds smaller actuators; to reach Dia 12 you have to change thread, because Dia 12 never appears on 1/4 in - that means PZB1203 on a 3/8 in port or PZB1204 on 1/2 in. If your port is already 3/8 in and you want to keep Dia 10 tube, PZB1003 is the direct equivalent with a bigger stud. The PT thread arrives with sealant applied, and the tube OD must match the socket exactly - a Dia 10 socket will not grip 8 mm or 12 mm tube.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 10 mm soft nylon or polyurethane tube to a 1/4 in PT male thread, with three push-in sockets and one threaded leg forming the four-way cross. No L/min or Cv figure is published for this family; capacity follows the Dia 10 bore.
Not on this SKU. On the PZB ladder a 1/4 in thread supports only Dia 6, 8 and 10 tube, and Dia 10 is the top of that port. Dia 12 exists only on the 3/8 in (PZB1203) and 1/2 in (PZB1204) versions, so move up a thread size if you need the larger bore. And because tube OD must match exactly, a Dia 10 socket will not seal on 12 mm tube no matter how hard it is pushed in.
