About the Airtac PZB Cross Threaded Fitting PZB801D-S
The AirTAC PZB801D-S is a threaded cross from the resin one-touch family: a single 1/8in PT male thread on one face and four Dia 8 push-in outlets arranged around it, so one port on a manifold or valve can feed four separate tube runs. Push the tube home and the internal chuck grips it under the stainless spring gasket; press the release ring and the tube comes free again. The D in the code marks the black colour version.
This -S variant carries a SUS304 stainless stud while the body itself stays PBT, so the corrosion-critical male thread that screws into the port is stainless without the price of a full stainless part. Ratings are identical to the standard PZB801D: 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C, and -750 mmHg vacuum. The thread arrives with sealant applied. Note that the PZB range offers no M5 thread and no Dia 4 tube at all - this 1/8in port serves Dia 6 and Dia 8 only.

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 PZB801D-S Is Used
Control panel manifold splitting
Screw the 1/8in PT stud into a manifold plate outlet inside a machine control cabinet and split the supply four ways to a Dia 8 main run and three Dia 8 drops for a pneumatic indicator, air jet and two small cylinders - all from one port.
Pick-and-place gripper distribution
On a pick-and-place robot head, the cross lets one supply line from the wrist feed four suction cup ejector lines or four gripper cylinders in balanced pairs, keeping air path lengths equal so all cups release together.
Textile machine yarn-threading airlines
Textile spinning and winding machines run many short air blasts from a single valve. A threaded cross at the valve outlet feeds four Dia 8 nozzles at once, and the SUS304 stud resists corrosion in humid, lint-laden machine environments.
Is the Airtac PZB Cross Threaded Fitting PZB801D-S the Right Part?
On the 1/8in PT thread the PZB ladder has just two rungs: Dia 6 (PZB601D-S) and this Dia 8. Stepping down to Dia 6 halves the branch bore for lighter actuators; there is no Dia 10 on 1/8in - the next size up is PZB1002D-S, which moves to a 1/4in PT thread, so check your port before stepping up. If you need only two or three branches instead of four, a PEB branch tee or PYB Y saves the unused leg of the cross.
Tube OD must match exactly: the four chucks here hold 8mm soft nylon or polyurethane and nothing else - a 5/16in or 1/4in tube will neither seat nor seal. Match the 1/8in PT male thread to a tapped port and seal with the factory-applied thread coating.
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-S FAQ
This is a one-touch threaded cross with four Dia 8mm tube outlets and a single 1/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), and proof pressure is 1.5 MPa. Operating temperature is -20 to +70 C with soft nylon or polyurethane tubing. The stud is SUS304 stainless steel; the body is PBT with POM release buttons, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring.
No. AirTAC re-rates nothing on the -S variant: the SUS304 stud replaces the standard stud material for corrosion resistance, and every figure stays the same - 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C, -750 mmHg vacuum. The body remains PBT, so do not treat this as a full stainless fitting; the practical benefit is a corrosion-resistant threaded interface where it screws into the port.
