About the Airtac PZB Cross Threaded Fitting PZB801D
The PZB801D is an AirTAC one-touch threaded cross in the resin/brass family: a four-way junction that puts a 1/8" PT male thread on one branch and three push-in ports for Dia 8 mm soft nylon or polyurethane tube on the other three. Push the tube home and the internal chuck grips it; press the POM release ring and it lets go, so a four-branch node can be built or re-plumbed without tools.
This is the grey-standard PZB ladder finished in black - the D suffix changes the body colour on this series, which matters when a manifold sits on a dark machine housing or an enclosure front. The threaded port arrives with sealant already on the thread and seals straight into a PT-tapped port; note that the PZB range has no M5 option at all, so a 1/8" thread is already the smallest thread you can buy in this shape. Ratings: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C.

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 PZB801D Is Used
Electronics pick-and-place cells
Distributes one 1/8" PT supply to three Dia 8 lines feeding vacuum ejector blocks and gripper cylinders on a PCB pick-and-place head, with the black body blending into dark anodised gantry plates.
Control-panel rear manifolds
Mounted close behind a machine electrical cabinet, the cross splits a feed line into three runs to solenoid valve stacks, keeping the fitting cluster visible and serviceable through the panel window.
Laboratory sample-handling rigs
On automated analyser and dispensing stations, the tool-free release ring lets technicians re-route Dia 8 air lines between assay modules without unscrewing a single threaded joint.
Is the Airtac PZB Cross Threaded Fitting PZB801D the Right Part?
On the 1/8" thread row of the PZB table only Dia 6 and Dia 8 exist, so PZB801D is the largest cross AirTAC makes with a 1/8" port - there is no Dia 10 or 12 to step up to on this thread. Step down to PZB601 for a Dia 6 network that feeds lighter actuators and sensors; step up in bore by moving to PZB802, which keeps the same Dia 8 tube but changes the thread to 1/4" for a larger port on the manifold. The tube OD must match exactly - a Dia 8 chuck will not seal on 5/16" or 10 mm tube.
Choose a PZB when four lines genuinely meet at one point; if two of the branches are dead ends feeding opposite directions, a PEB branch tee or a PYB Y may route the tubing more cleanly.
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 PZB801D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr), operating temperature -20 to +70 C. It is a resin one-touch threaded cross with three ports for Dia 8 mm soft nylon or polyurethane tube and one 1/8" PT male thread, in the black (D) colour option.
AirTAC's PZB interface table lists 1/8" only for Dia 6 and Dia 8 tube, so PZB801D is the ceiling for this thread - Dia 10 and Dia 12 crosses exist but require a 3/8" or 1/2" thread. If your line is Dia 8 and you need more port capacity, PZB802 keeps the same tube and moves the thread to 1/4".
