About the Airtac PZB Cross Threaded Fitting PZB802D
The PZB802D is an AirTAC PZB threaded cross, a four-way one-touch fitting that lets a single 1/4" PT port feed or split between four Dia 8 mm soft nylon or polyurethane lines at 90 degrees to each other. Push each tube home and the internal chuck grips it; press the POM release ring to free it again. The D suffix means the body is moulded in black rather than the standard grey, which suits dark machine frames and panels where grey hardware stands out visually.
This is the resin and brass profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The external thread is PT with sealant applied at the factory, so it seals into a tapered port without extra tape in most cases. Internally you get a POM release ring and chuck, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring around the tube.

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 Is Used
Packaging machine air distribution
A 1/4" port on the machine manifold splits four ways to feed Dia 8 lines running to sealing jaws, gripper pads and a reject cylinder on a cartoning line, all from one junction point.
Fixture plate junction block
Mounted on a weld fixture or assembly fixture, the cross turns one supply connection into four equally spaced branch points for clamps and sensors, cutting the number of individual fittings needed.
Conveyor stopper and sensor feed
Four Dia 8 lines - two stopper cylinders, a part-present sensor and a blow-off nozzle - hang off a single black cross tucked behind the conveyor side rail where it stays invisible against the frame.
Is the Airtac PZB Cross Threaded Fitting PZB802D the Right Part?
On the 1/4" row of the PZB ladder, the neighbouring sizes are PZB602 (Dia 6 tube) below and PZB102 (Dia 10 tube) above. Stepping down to 6 mm reduces the bore feeding each leg, which is fine for small actuators but restricts air hungry cylinders; stepping up to 10 mm lowers restriction per leg at the cost of a bulkier cross. Note the PZB never starts below Dia 6 - there is no Dia 4 cross in this range, so a 4 mm junction needs a different family. Always match tube OD exactly: a Dia 8 chuck will not seal on 5/16" tube. Choose this cross over a tee when a machine junction genuinely has four equal legs - a distributor block on a fixture plate is the classic case. If your port is 3/8" or 1/2", PZB crosses exist in those threads too, but they are separate SKUs.
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 FAQ
It is a resin one-touch threaded cross accepting Dia 8 mm soft nylon or polyurethane tube on all four legs, with a 1/4" PT male thread carrying factory-applied sealant. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and operating temperature -20 to +70 C. The D suffix gives a black body instead of grey.
The PT thread arrives with sealant already applied, so additional taping is normally unnecessary; if you remove and refit the part, inspect the sealant coating first. For Dia 6 tube on the same 1/4" thread, order the PZB602 - the chuck size must match the tube OD exactly, and forcing 6 mm tube into this Dia 8 fitting will leak or blow off under pressure.
