About the Airtac PZB Cross Threaded Fitting PZB802-S
The PZB802-S is an AirTAC PZB threaded cross: one 1/4in PT male port plus three one-touch legs that each grip 8mm outside-diameter tube. It is the only shape in the one-touch range that turns a single threaded supply into a four-way node, so a solenoid outlet can feed three tube branches without a separate union cluster. To connect, push the tube straight into the leg until it bottoms out; the stainless spring gasket and chuck grip it against the NBR O-ring seal. Pressing the release ring frees the tube again.
The -S suffix means the male stud is Stainless steel 304; the cross body itself stays PBT, so this is a stud-level upgrade rather than a solid stainless part. Ratings are unchanged from the standard PZB: 0 to 1.0 MPa working pressure (0-10 kgf/cm2), -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C, with soft nylon or polyurethane tubing. Threaded ends arrive with sealant applied; there is no M5 version in this series.

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 PZB802-S Is Used
Four-station rotary indexing table
Mount the cross at the centre post of a packaging machine's indexing dial so one 1/4in PT supply feeds clamp cylinders at three Dia 8 tube stations from a single node.
Wash-down bench on a food line
On a rinse table where hoses are hosed down daily, the SUS304 stud stands up to splash and wash-down better than a plain brass stud while the PBT body shrugs off cleaning agents.
Multi-jet chip-clearing manifold
Feed threeDia 8 air-jet nozzles around a machined-aluminium part from one threaded drop on the CNC enclosure wall, replacing three separate elbows and a union tee with one cross.
Is the Airtac PZB Cross Threaded Fitting PZB802-S the Right Part?
On the 1/4in thread row of the PZB ladder, this Dia 8 cross sits between the PZB602-S (Dia 6 tube) below and the PZB1002-S (Dia 10 tube) above. Stepping to 6mm lightens the node for small pick-and-place tubing runs; stepping to 10mm raises the bore for longer branch lines where pressure drop matters. If your port is only 1/8in, the Dia 8 tube size also exists on that row as PZB801-S, and a 3/8in version is available as PZB803-S.
The PZB series starts at Dia 6 with a 1/8in thread as its smallest option - there is no M5 and no Dia 4 cross, so this shape cannot replace a mini PC-style fitting in tight 4mm circuits. Match the 1/4in PT thread to a PT port and remember the tube OD must be exactly Dia 8; a 5/16in or 1/4in tube will not seal in these legs.
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 PZB802-S FAQ
Working pressure 0 to 1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. This part takes Dia 8 outside-diameter soft nylon or polyurethane tube on all three one-touch legs and has a 1/4in PT male thread. The -S variant has a SUS304 stud; body material, ratings and dimensions match the standard PZB802 exactly.
No. On the PZB family the SUS304 upgrade applies to the male stud only - the cross body remains PBT with a POM button and chuck, aluminium guide, stainless spring gasket and NBR O-ring. AirTAC publishes the same pressure, vacuum, proof and temperature figures as the standard version, and the dimension tables are identical, so you can swap a PZB802 for a PZB802-S without re-plumbing anything.
