About the Airtac PEW T-Type Side Reducing Tee Fitting PEW8-6D
The PEW8-6D is an AirTAC different diameter union Y, a tube-to-tube fitting with no external thread. It takes Dia 8 mm tubing on the inlet leg and splits the flow into two branches, one of which is a Dia 6 mm leg, so a single supply run can feed a smaller line without adapters or a threaded tee. The D suffix means the body is moulded in black rather than the standard grey, which on this series changes the body itself, not just the button.
Like every one-touch fitting in this catalogue, you push the soft nylon or polyurethane tube straight into the chuck until it bottoms out; the stainless spring gasket and collet grip it, and the NBR O-ring seals it. Pressing the POM release ring against the body frees the tube again. This is the resin profile part, rated 0 to 1.0 MPa (0 to 10 kgf/cm2) working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. There is no thread to seal, so no sealant or tape is involved anywhere on this fitting.

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 PEW8-6D Is Used
Vacuum ejector feed on a pick-and-place head
On a packaging machine pick-and-place, a Dia 8 supply drop from the gantry is split with this Y so one leg feeds the ejector and the Dia 6 leg runs to the pad's blow-off, all without a threaded tee or adapter stack.
Bottling line air-rinse nozzle split
An air-rinse section on a beverage bottling line often runs Dia 8 headers to a row of small Dia 6 nozzle drops; this union Y takes the header flow and branches it cleanly, and the black body blends with dark machine frames.
Pneumatic counting sensor leg on a conveyor
A conveyor control cabinet can tee a Dia 6 sensing-jet line off a Dia 8 cooling blast line using this Y, so the sensor jet and the part-cooling nozzle share one supply run without throttling hardware.
Is the Airtac PEW T-Type Side Reducing Tee Fitting PEW8-6D the Right Part?
This SKU sits in the middle of the different-diameter Y ladder. If both legs of your branch were the same size, use a plain PE union tee in Dia 6 or Dia 8 instead; if you need a 90-degree branch rather than the angled Y sweep, the PED or PEB threaded tees cover that shape. The Y body gives two diverging legs from one inlet, which is the right answer when one Dia 8 drop has to feed two Dia 6 sub-circuits at once. Larger different-diameter unions continue through Dia 10 and Dia 12 pairs if your step is bigger.
Check your tubing before ordering: the Dia 6 leg accepts only genuine 6 mm OD soft nylon or polyurethane. A nominal 1/4 inch tube measures about 6.35 mm and will not seat or seal in a Dia 6 chuck, so it must never be forced onto this port.
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 PEW8-6D FAQ
It is an AirTAC different diameter union Y joining Dia 8 mm tubing to two legs, one of which is Dia 6 mm, with no external thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr), and operating temperature -20 to +70 C. It suits soft nylon or polyurethane tubing and the D suffix gives a black body. This is the resin one-touch profile, not the 0.9 MPa / 150 C metal BP line.
No sealant is needed or possible here because the PEW8-6D has no threaded port, only tube chucks. The chuck is also engineered for soft nylon or polyurethane only; hard nylon or rigid plastic tube will not deform into the spring gasket and can weep or blow off, so stick to soft-walled tube in exactly Dia 8 mm and Dia 6 mm OD.
