About the Airtac PEW T-Type Side Reducing Tee Fitting PEW12-10D
The PEW12-10D is an AirTAC PEW different diameter union tee: a tube-to-tube, three-way fitting that splits a Dia 12 mm main line into a Dia 10 mm branch without any threaded port in between. Both outer ports take the larger 12 mm tube, the branch takes 10 mm, so a single part does the work of a tee plus a reducer. Push each tube home until it bottoms in the chuck and the stainless spring gasket grips it; press the POM release ring to free it again.
This is the resin and brass one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service range of -20 to +70 C. The body is black because the D suffix on this family changes the whole body colour, not just the release button as it does on PC and POC straight connectors. Tubing must be soft nylon or polyurethane; the chuck is not designed to seal on rigid or thick-wall hose.

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 PEW T-Type Side Reducing Tee Fitting PEW12-10D Is Used
Packaging machine branch line
Split a Dia 12 mm nylon main feed on a cartoning or wrapping machine into a Dia 10 mm branch that supplies a downstream pneumatic gripper or clamp cylinder, in one push-fit part.
Black tubing in visible frames
On extruded-aluminium machine frames and robotics cells dressed with black 12 mm and 10 mm polyurethane tubing, the D-suffix black body keeps the air routing visually consistent instead of showing grey fittings mid-run.
Vacuum pick-and-place split
Rated to -750 mmHg, so a Dia 12 mm vacuum line from the ejector can be teed and stepped down to Dia 10 mm drops feeding suction cups on a sheet-handling or carton-raising station.
Is the Airtac PEW T-Type Side Reducing Tee Fitting PEW12-10D the Right Part?
Step down to PEW10-8 when your main line is 10 mm and the branch actuator needs 8 mm - everything else about the part stays the same. There is no larger variant: Dia 12 is the biggest tube size in this catalogue, so PEW12-10 is already at the top of the different-diameter ladder. If both legs are the same diameter, a plain PE union tee is the lighter answer; if you want a swept Y rather than a right-angle branch, the PYW different diameter union Y is the equivalent shape.
Tube OD must match each port exactly - the 12 mm ports will not hold 10 mm tube and the 10 mm branch will not hold 12 mm, so measure the actual tube wall-marking before ordering. Capacity is set by the smaller bore: expect the 10 mm branch to pass less air than the 12 mm through-flow.
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 PEW T-Type Side Reducing Tee Fitting PEW12-10D FAQ
It is a different diameter one-touch union tee joining Dia 12 mm tube on the two through-ports to Dia 10 mm tube on the branch, finished black (D suffix). Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure goes to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. Use soft nylon or polyurethane tubing only.
No. Each port grips one tube OD only: the two in-line ports accept Dia 12 mm and the branch accepts Dia 10 mm. A 12 mm fitting will not seal on 10 mm tube or the reverse, because the chuck and gasket are sized to the exact wall diameter. If you need equal diameters throughout, order a standard PE union tee in a single size instead.
