About the Airtac PZB Cross Threaded Fitting PZB603-S
The AirTAC PZB603-S is a threaded cross from the resin one-touch range: a single 3/8in PT male stud with three push-in ports, all sized for Dia 6mm soft nylon or polyurethane tube. Push each tube home and the internal chuck grips it; press the POM release ring to free it again. In one part it turns a single threaded supply port into a four-way node, with no separate tees, studs or elbows to seal.
The -S suffix fits a SUS304 stainless stud to a PBT body, so the exposed thread resists corrosion while the fitting's ratings and dimensions stay exactly as standard. This is the normal resin profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C. Threads arrive with sealant applied, and note there is no M5 option anywhere in the PZB range, so 1/8in is the smallest stud offered.

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 PZB603-S Is Used
Rotary indexing table base plate
On a packaging machine's indexing dial, one 3/8in port in the fixed base can feed three separate 6mm gripper or clamp circuits through this cross, instead of machining three threaded ports into a crowded base plate.
Robotic gripper manifold at the wrist
End-of-arm tooling often runs 6mm tubing to several suction cups from one pilot feed. The PZB603-S splits that feed into three equal lines right at the wrist, keeping each hose run short and swappable by hand.
Labeler head blow-off circuit
A pressure-sensitive labeler needs three hold-down or blow-off nozzles per head. This cross divides the 3/8in pilot feed into three 6mm drops at the header, and the SUS304 stud tolerates wash-down splash around the conveyor.
Is the Airtac PZB Cross Threaded Fitting PZB603-S the Right Part?
On the 3/8in thread, Dia 6 is the smallest tube in the ladder, so there is no smaller sibling on this stud; the step up is PZB803 for Dia 8 lines. On the thread side, PZB602 (1/4in) is the step down, and 3/8in is the largest thread AirTAC pairs with Dia 6 on this series, because 1/2in only starts at Dia 8. Tube OD must match exactly - a Dia 6 port will not grip 1/4in (6.35mm) tube.
If your circuit is a three-way split rather than four-way, the PEB branch tee or PED run tee is the simpler shape and saves a capped leg. Where you need different tube sizes feeding off one stud, move to the reducer branches instead of adapting with reducers on every port.
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 PZB603-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. This SKU is the threaded cross with a 3/8in PT male stud and three Dia 6mm one-touch tube ports; the stud is SUS304, the body is PBT, and the seal is an NBR O-ring.
No. On the PZB series AirTAC keeps the cross body in PBT and supplies only the threaded stud in SUS304, so the stainless element is the part that protrudes from the port. Every pressure, vacuum, proof and temperature figure is identical to the grey standard version, and the push-in chucks, release rings and seals are unchanged.
