About the Airtac PZB Cross Threaded Fitting PZB1003D-S
The PZB1003D-S is an AirTAC PZB threaded cross, a one-touch fitting that sets a 3/8 in PT male thread into a cross junction of Dia 10 mm soft nylon or polyurethane tubing. Push each tube home and the internal chuck grips it for a pressure-tight joint; press the release ring and the tube frees straight out. The PZB prefix means the thread sits on a cross body, so several tube lines can meet at a single threaded supply point instead of being spliced from separate elbows and tees.
This is the resin/brass spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr) and a temperature window of -20 to +70 C. The trailing -S makes this the SUS304 variant. On the PZB family that means the male stud is stainless steel 304 while the body remains PBT - so you get a corrosion-resistant thread interface without paying for, or claiming, a solid stainless body. The D suffix gives the black body finish, and the PT thread arrives from AirTAC with sealant already applied.

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 PZB1003D-S Is Used
Wash-down packaging machinery
On food packaging lines hosed down between shifts, the SUS304 stud at the 3/8 in port resists the corrosion that chews plain brass studs, while the PBT cross body sits out of the spray path feeding Dia 10 drops to the sealing heads.
Control cabinet pneumatic distribution
A cross on a 3/8 in PT bulkhead fitting inside a machine control cabinet lets one feed split four ways - two Dia 10 lines forward, two back - without stacking a tee on an elbow and its extra leak joints.
Electroplating and chemical rinse stations
Near plating tanks and rinse lines where splashed chemistry attacks brass, the stainless-stud PZB1003D-S in black holds Dia 10 actuator lines to the 3/8 in supply manifold through the -20 to +70 C window these stations work in.
Is the Airtac PZB Cross Threaded Fitting PZB1003D-S the Right Part?
On the PZB ladder at 3/8 in thread, the tube sizes either side of Dia 10 are Dia 8 (PZB803) and Dia 12 (PZB1203). Stepping down to Dia 8 suits lighter cylinder and valve ports; stepping up to Dia 12 pays off on short, high-consumption trunk runs where every bit of bore counts. If the thread is what needs to change, Dia 10 is also offered on PZB in 1/4 in (PZB1002) and 1/2 in (PZB1004) - match the thread to the port on the machine, not to the tube.
Tube OD must match exactly: a Dia 10 one-touch chuck will not seal on 3/8 in (9.5 mm) tube, even though the numbers look close. If you actually need to reduce from a larger trunk to Dia 10 at the thread, a reducer branch in the PKD family is the correct shape instead of forcing a mismatch.
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 PZB1003D-S FAQ
It is an AirTAC PZB threaded cross for Dia 10 mm soft nylon or polyurethane tube with a 3/8 in PT male thread, black finish. Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr), temperature -20 to +70 C. The -S suffix means the male stud is SUS304 stainless steel; the body is PBT. Flow is published by AirTAC as a characteristic curve only, sized by the 10 mm bore rather than a Cv figure.
No. AirTAC ships every threaded part in this catalogue with sealant already applied to the PT thread, so the PZB1003D-S can be wound straight into the port. Hand-tight plus a modest spanner turn is normally enough; over-tightening a pre-sealed PT thread risks cracking the port. M5 sizes are the exception in the range and use a sealing gasket instead of thread sealant.
