About the Airtac PEW T-Type Side Reducing Tee Fitting PEW10-8D
The PEW is AirTAC's different diameter union tee: a three-way push-in junction that splits one run of tubing into a 90 degree branch, with the reducing geometry built in. This version bridges a Dia 10 mm run to a Dia 8 mm branch, so a main air line can feed a smaller leg without an extra stepped union, and the D suffix gives the whole PBT body a black finish. Connection is one-touch: push soft nylon or polyurethane tube home and the internal chuck grips it, press the POM release ring and it frees.
It runs on the resin one-touch spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C, sealing on an NBR O-ring with a stainless spring gasket. Note that the -750 mmHg rating is not decorative: this tee can sit in a vacuum branch just as happily as in a pressure line, which matters on pick-and-place cells that share one vacuum generator across multiple cup circuits.

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 PEW10-8D Is Used
Vacuum cup circuit on a carton-erecting packer
Split a shared 10 mm vacuum line from a venturi generator down to an 8 mm leg feeding the cup manifold, using the -750 mmHg rating instead of adding a second generator.
Air jet feed on a weaving loom
Tap the 10 mm main air run along the loom frame and reduce immediately to an 8 mm drop for the weft-insertion jet, keeping the branch compact beside the harness.
Black-bodied branch on a robotics cell
Use the black PEW body on a dark anodised robot riser where a grey tee would stand out, running a 10 mm supply to an 8 mm gripper purge line.
Is the Airtac PEW T-Type Side Reducing Tee Fitting PEW10-8D the Right Part?
Pick a PEW over an equal-bore PE tee when the branch circuit genuinely draws less air than the run, such as stepping a 10 mm manifold run down to an 8 mm leg feeding a single actuator or jet. The tube ladder in this catalogue runs from Dia 4 to Dia 12, so both bores in this pair sit in the middle of the range with a 12 mm-wide option above and a 6 mm-narrower option below; each step down trims the branch's carrying capacity, which is a function of bore, not of the fitting body.
Two sizing traps: first, because this is a reducing tee, each leg must see its own matched tube - the Dia 10 leg takes 10 mm OD tube, the Dia 8 leg takes 8 mm, and neither will grip anything else. Second, tube must be the soft nylon or polyurethane grades; rigid PA12 or steel tube will not seat on the chuck.
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 PEW10-8D FAQ
It is a different diameter union tee joining Dia 10 mm and Dia 8 mm soft nylon or polyurethane tube, with no threaded port (tube-to-tube only). Working pressure is 0 to 1.0 MPa, negative pressure is -750 mmHg, proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The D suffix denotes a black body.
On this series the change is bigger than on AirTAC's straight connectors: on PC and POC the D suffix only swaps the release button to black, but on the PEW the whole PBT body is moulded black. The pressure, vacuum and temperature ratings, materials inside the chuck, and dimensions are otherwise identical to the grey version.
