About the Airtac PEW T-Type Side Reducing Tee Fitting PEW10-8
The PEW10-8 is an AirTAC different diameter union tee from the resin one-touch range. It splits a Dia 10 mm tube run into a Dia 8 mm branch, all three legs gripping by push fit - there is no thread anywhere on this part, so no sealant or wrench is ever needed. Push the tube home and the internal chuck grabs the OD; press the release ring and the tube slides straight back out.
It runs on the standard resin spec profile, not the metal BP line: 0-1.0 MPa working pressure (0-10 kgf/cm2), -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The body is PBT with a POM release button and chuck, an NBR O-ring seals each leg, and the standard finish is grey - the D suffix order code is what selects black. Because it is tube-to-tube, the temperature limit at the top of the range is usually set by the tubing you pair with it, not the fitting itself.

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 PEW10-8 Is Used
Manifold drop to valve island
On a PCL air-prep manifold feeding a bank of solenoid valves, the PEW10-8 takes the Dia 10 trunk and tees off a Dia 8 branch sized to the island's inlet, without a single threaded joint to seal.
Packaging machine cylinder feed
A carton-forming station where one Dia 10 supply line diverges to two Dia 8 double-acting cylinder circuits - the reducing tee makes the split at the frame junction and releases in seconds during changeover.
Bench-top vacuum pick-and-place
On a lab automation gripper running at partial vacuum, the Dia 10 leg ties to the ejector line while the Dia 8 branch drops to the suction cup header, well inside the -750 mmHg (10 Torr) rating.
Is the Airtac PEW T-Type Side Reducing Tee Fitting PEW10-8 the Right Part?
This size steps a Dia 10 feed down to a Dia 8 branch, which is the natural move when a main air drop feeds a smaller actuator or valve island. The smaller step in the family runs 8 down to 6, useful for tight-flow signal and pilot lines; the larger step is 12 down to 10, used where the trunk carries more volume. Stepping down reduces the flow area available on the branch, so tie the branch bore to what the actuator actually consumes rather than to what fits the port.
If you need the same 10-to-8 reduction in a straight in-line body, AirTAC's PG different diameter straight covers it; if you need it at a 90 degree corner, the PV union elbow family is the shape to look at. Whichever shape you choose, tube OD must match the fitting exactly - a Dia 8 leg will not seal or hold 5/16 inch tube, only genuine Dia 8 mm soft nylon or polyurethane.
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 PEW10-8 FAQ
It is a different diameter union tee joining Dia 10 mm and Dia 8 mm soft nylon or polyurethane tube, with no thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, and temperature range -20 to +70 C. Body is PBT with a POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring, in grey standard finish.
No. The PEW10-8 is entirely tube-to-tube, so the thread sealant that AirTAC pre-applies to its threaded one-touch parts has no role here. Cut the tubing square, push it into each leg until it bottoms, and the chuck grips it. To remove a line, press the release ring on that leg and pull the tube out - no tools and no re-sealing at any point.
