About the Airtac PZB Cross Threaded Fitting PZB1203-S
The AirTAC PZB1203-S is a one-touch threaded cross: a single 3/8in PT male port on one leg and three push-in Dia 12 mm outlets on the other three, letting one threaded connection split air into three tube lines at a right-angle cross pattern. You push each 12 mm tube straight into its chuck until it bottoms out, the stainless spring gasket and chuck grip it against both pressure and vacuum, and pressing the release ring frees it again. The SUS304 stud arrives with thread sealant already applied, so the port side seals on first assembly.
This is the resin one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg, and a service temperature of -20 to +70 C with soft nylon or polyurethane tubing. On this -S variant the stud is SUS304 stainless steel while the cross body remains PBT, so it suits corrosive or wash-prone areas around the port thread without changing any rating. Worth knowing when ordering the family: PZB never offers M5 and never offers Dia 4 tube, so Dia 12 is already at the top of its size range.

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 PZB1203-S Is Used
Bottling line rinse header
Screw the 3/8in stud into the rinse manifold feed and run three Dia 12 drops to spray nozzles along the rinser carousel, all split from one sealed port.
Palletiser gripper air distribution
Mount the cross at the end of a robotic palletiser arm so one supply line fans out into three Dia 12 tube runs feeding suction cups and gripper cylinders.
Can seamer tooling cluster
Feed seamer rollers, counter-pressure blow-off and a lift cylinder from a single 3/8in port, with the SUS304 stud standing up to frequent washdown around the port.
Is the Airtac PZB Cross Threaded Fitting PZB1203-S the Right Part?
Step down to the PZB1003 and you give up 2 mm of bore on all three outlets, which trims the flow path feeding each drop from the cross. There is no larger tube on the 3/8in row - Dia 12 is the ceiling here - so if the thread is the thing to grow, move to PZB1204 and keep the same 12 mm tubes on a 1/2in PT port instead. Both options sit inside PZB's published ladder of 6, 8, 10 and 12 mm tubes.
Match the 3/8in PT stud to a port actually tapped 3/8in, and remember the tube rule is absolute: a Dia 12 fitting grips only 12 mm OD metric tube. It will not clamp 1/2in imperial tube, which measures about 12.7 mm and will leak or blow off.
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 PZB1203-S FAQ
It is a one-touch threaded cross joining three Dia 12 mm tube outlets to a 3/8in PT male port. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability -750 mmHg, and the temperature range is -20 to +70 C with soft nylon or polyurethane tubing. The -S variant carries a SUS304 stud on the port side; the ratings are identical to the standard grey version.
No. One-touch chucks grip one exact outside diameter, and a Dia 12 fitting is built for 12 mm metric tube only. 1/2in imperial tube measures roughly 12.7 mm OD, so it will not seal in the chuck. Use a genuinely imperial fitting range for imperial tube, or step the PZB family itself: this SKU's published ladder runs Dia 6, 8, 10 and 12 on threads from 1/8in to 1/2in.
