About the Airtac PZB Cross Threaded Fitting PZB1004D
The PZB1004D is an AirTAC threaded cross from the PZB range: one 1/2in PT male port and three push-in ports, all taking Dia 10 mm soft nylon or polyurethane tubing. A single supply line enters through the thread and the fitting hands off to three tube runs at once, so a cross saves a tee plus a union wherever two directions split off the main feed. Connection is genuinely one-touch - push each tube home until it stops and the stainless spring gasket and chuck grip it; press the release ring and the tube frees again. The D suffix marks the black version, and on the PZB series (unlike PC or POC) the black moulding covers the whole body, not just the button.
This is the resin fitting profile, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The release button and chuck are POM, the guide is aluminium alloy and the seal is NBR; the threaded stud is brass and arrives with sealant already applied, ready for a PT port.

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 PZB1004D Is Used
Rotary indexing table clamp feed
A single 1/2in PT riser on the machine base feeds three Dia 10 lines to the clamp cylinders around the dial - one cross at the centre replaces a tee and a separate union, and the black body stays unobtrusive on painted frames.
Corrugated box case erector
Vacuum-bar and flap-fold cylinders cluster at the top of the frame; a threaded cross splits the 1/2in supply into three tube drops, keeping all push-in joints outside the moving tongue of the erector.
Bottle rinser air knife branch
On a rotary bottle rinser the blow-off nozzles sit at three angles to one supply; the cross feeds all three Dia 10 nozzle lines from a single threaded stub, so nozzle tuning never disturbs the main plumbing.
Is the Airtac PZB Cross Threaded Fitting PZB1004D the Right Part?
On the PZB 1/2in row only Dia 8, Dia 10 and Dia 12 exist, so the neighbours are clear: step down to PZB804 if the branch lines are 8 mm, or up to PZB1204 for 12 mm trunk feeds. Bore changes what the cross can feed - a 10 mm bore suits cylinder ports up to roughly Dia 10 actuators, while 8 mm keeps things compact at the cost of capacity per branch. If your port is 1/4in, the same Dia 10 tube is served by PZB1002 instead; note PZB is never offered in M5 or Dia 4, so the smallest PZB of any thread is Dia 6.
Check the geometry before you order: a cross is right when three branches leave one threaded supply. For a panel pass-through use the PM bulkhead union or PLM bulkhead elbow instead, and where a branch must swivel to meet an actuator, a PH universal elbow removes the alignment problem. Tubing OD must match exactly - Dia 10 tube in a Dia 10 port, never 3/8in or 1/4in 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 PZB1004D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It is a threaded cross with a 1/2in PT male port and three push-in ports for Dia 10 mm soft nylon or polyurethane tubing, finished in black (D suffix). Note this is the resin profile; AirTAC's metal BP line is rated lower at 0.9 MPa but survives up to 150 C.
AirTAC ships PZB threaded parts with sealant already applied to the thread, so the first installation into a PT port needs nothing extra. If you ever unscrew and refit the cross, reapply a compatible PTFE tape or pipe sealant first, and keep sealant off the first thread so fragments cannot migrate into the push-in chuck and hold a tube open.
