About the Airtac PZB Cross Threaded Fitting PZB802D-S
The AirTAC PZB802D-S is a threaded cross from the one-touch fitting range: one 1/4in PT male thread turns a single port into three Dia 8 mm push-in outlets set at 90 degrees around the body. Push each tube home and an internal chuck grips the OD against a stainless spring gasket; press the release ring square to the port and the tube slides out again for rework. The D suffix specifies a black body.
Ratings follow the resin one-touch profile: 0-1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and -20 to +70 C with soft nylon or polyurethane tubing. The trailing -S fits a SUS304 stainless steel stud on this variant; the body itself remains PBT, so the thread interface gains corrosion resistance without any change to the published pressure or temperature figures.

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.

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 PZB802D-S Is Used
Cartoning machine cross feed
One 1/4in tapping on a cartoner's air manifold splits three ways into Dia 8 lines serving two box-clamp cylinders and a small vacuum ejector, all from a single push-in cross.
Plating line instrumentation tee-off
The SUS304 stud keeps the threaded connection sound in the humid, chemically laden air above plating tanks, where a plain brass stud can dull and seize over time.
Pick-and-place gripper distribution
Mounted at the wrist of a pick-and-place robot, the cross feeds three Dia 8 gripper lines from one riser, keeping the plumbing to a single point on the moving carrier.
Is the Airtac PZB Cross Threaded Fitting PZB802D-S the Right Part?
On the PZB ladder this Dia 8 size sits between PZB602 (Dia 6, same 1/4in thread) and PZB1002 (Dia 10). Stepping down to Dia 6 suits light clamp and ejector circuits where the fitting face is cramped; stepping up to Dia 10 buys effective capacity for longer runs, because flow capacity tracks the tube bore rather than the thread. PZB is deliberately not offered in Dia 4 or in M5, so Dia 6 is the floor of this family. The 1/4in port also accepts PZB601 and PZB801 builds on 1/8in if your manifold drilling is smaller.
Match the 1/4in PT male thread to the port and seal with tape or sealant as your standard practice dictates. Tube OD must match the port exactly: a Dia 8 chuck will not seal on Dia 6 or Dia 10 tube, so check the printed marking on the tubing before ordering.
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 PZB802D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C, for soft nylon or polyurethane tubing. This SKU is the threaded cross with a Dia 8 mm tube bore on three outlets and a 1/4in PT male thread, finished in black, with a SUS304 stainless steel stud fitted.
The 1/4in port is offered in Dia 6, Dia 8 and Dia 10 only, so this Dia 8 version is the middle of that run. On other threads the range widens: 1/8in exists in Dia 6 and Dia 8, while 3/8in and 1/2in run from Dia 6 up to Dia 12. There is no Dia 4 and no M5 anywhere in the PZB family.
