About the Airtac PZB Cross Threaded Fitting PZB801
The PZB801 is an AirTAC PZB threaded cross, the four-way node of the resin one-touch range. It screws into a 1/8 inch PT male port and gives you three push-in ports for Dia 8 mm tube, all branching off that single threaded inlet in a cross formation.
Push the Dia 8 tube into each port and the stainless spring gasket and chuck grip it for an instant seal; press the POM release ring to let it go. This is the resin and brass spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a -20 to +70 C service window. The body is PBT over a brass stud, the thread arrives with sealant pre-applied, and it suits soft nylon or polyurethane tubing.

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 PZB801 Is Used
Four-leg jet header on a screen printer
One 1/8 in tap on the printer's air manifold feeds three Dia 8 nozzle lines through a single PZB801, cleaning misprinted boards with a symmetric four-way layout instead of a tee-and-elbow chain.
Vacuum degassing chamber manifold
The -750 mmHg rating lets a lab rig pull three Dia 8 evacuation lines from one PZB801 mounted at the chamber port, keeping the plumbing symmetric so no branch is favoured over another.
Web-cleaning blow-off station
On a film conveying line, the PZB801 splits one Dia 8 supply into three equal cross-linked air knives above the web, halving the fittings count versus separate elbows at each nozzle.
Is the Airtac PZB Cross Threaded Fitting PZB801 the Right Part?
The PZB ladder starts at Dia 6 with no M5 thread and no Dia 4 option, so PZB601 is the size below this one; stepping down halves the bore per leg and suits slimmer signal or jet lines. The step up is PZB802, the same Dia 8 bore on a 1/4 inch PT thread - same tube, larger port. If you need Dia 10 or Dia 12 legs, the PZB threaded cross only offers them from 3/8 inch thread upward. Whichever way you go, tube OD must match the port exactly - a Dia 8 port will not seal on 5/16 inch or 10 mm tube.
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 PZB801 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. This SKU is the threaded cross for Dia 8 mm soft nylon or polyurethane tube on a 1/8 inch PT male thread.
No. The PZB threaded cross starts at Dia 6 tube with a 1/8 inch thread as the smallest option - there is no M5 thread and no Dia 4 leg in the series. Use a PEB male branch tee or a PG different-diameter union if you need to step a Dia 6 or Dia 4 line off a larger branch.
