About the Airtac PEG T-Type Concentric Reducing Tee Fitting PEG8-6
The PEG8-6 is an AirTAC different diameter union tee from the PEG/PEW reducer-tee family: a three-way fitting where the two collinear legs accept Dia 8 mm tube and the branch accepts Dia 6 mm tube. It has no thread at all - every port is a one-touch tube socket, so the whole junction sits in the tubing run rather than on a valve or cylinder port. To make a joint you push soft nylon or polyurethane tube straight into the socket until it bottoms out; the POM chuck grips the tube wall, a stainless spring gasket and NBR O-ring seal it, and pressing the release ring frees the tube again.
This is a resin-line fitting, so it carries the resin spec profile, not the metal BPC figures: 0 to 1.0 MPa working pressure, vacuum capability down to -750 mmHg (10 Torr), a 1.5 MPa proof pressure and a -20 to +70 C temperature window. The body is grey as standard, and the D suffix variant changes the body to black. Because nothing on this tee is metal-threaded, it also suits circuits where you want to avoid thread sealant entirely.

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 PEG T-Type Concentric Reducing Tee Fitting PEG8-6 Is Used
Vacuum pick-and-place on a carton erector
Suction cups fed by 6 mm polyurethane tube can be teed off an 8 mm vacuum main with the PEG8-6, and the -750 mmHg (10 Torr) negative pressure rating means the junction holds under full vacuum without a separate sealed fitting.
Labeling-head actuator drop on a packaging line
Where an 8 mm supply run from the FRL feeds a 6 mm line to a small labeling or stamping cylinder, the different diameter tee makes the split at the point of use, saving a reducer plus a standard tee.
Bench distribution on an electronics assembly cell
An 8 mm air rail along a soldering or pick-and-place bench can branch to 6 mm drops at each station, with each operator releasing and re-routing a drop from the same tee as the cell layout changes.
Is the Airtac PEG T-Type Concentric Reducing Tee Fitting PEG8-6 the Right Part?
Step down and the branch gets smaller: PEG6-4 pairs a Dia 6 main with a Dia 4 branch, the choice when you are feeding a thin signal line or a miniature cylinder off a larger run. Step up to PEG10-8 and you gain bore, which matters on longer runs where a Dia 6 branch would choke flow through the tee - capacity on these fittings tracks the smallest tube you insert, not the fitting body. If you do not need the third leg, the PG different diameter straight union does the same bore change in two ports, and the PKG reducer triple branch union adds two equal branches instead of one.
Two checks before ordering. First, tube OD must match the socket exactly - a Dia 6 fitting will not hold 1/4 inch (6.35 mm) tube and an 8 mm socket will not grip a 6 mm line, so measure the tube, not the old part. Second, the tee must match the tube material: soft nylon or polyurethane only. Semi-rigid nylon or braided tube will not seal against the chuck and will leak or blow out under pressure.
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 PEG T-Type Concentric Reducing Tee Fitting PEG8-6 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and operating temperature -20 to +70 C. The fitting joins Dia 8 mm tube on the two collinear legs and Dia 6 mm tube on the branch; it is a resin-line one-touch tee in grey as standard, and the D suffix gives a black body.
No. Each socket grips and seals one tube OD only - the Dia 8 ports take 8 mm tube and the Dia 6 branch takes 6 mm tube, and nothing in between will seal on the chuck. Use soft nylon or polyurethane tube, and if you need another bore ratio, AirTAC makes the ladder in PEG6-4 and PEG10-8, with PG straight reducers available when you only need a two-way change.
