About the Airtac PEG T-Type Concentric Reducing Tee Fitting PEG10-8
The PEG10-8 is an AirTAC PEG different diameter union tee, an all-tube fitting with no port thread at all. It takes a Dia 10 mm tube into one way and Dia 8 mm tubing into the other two, so a single 10 mm feeder can be teed into two 8 mm drop lines without an adapter and without a second joint to leak. Because it is tube-to-tube, there is no thread to seal, no sealant to apply and no torque to get wrong.
One-touch operation is the same as the rest of the AirTAC resin line: push the soft nylon or polyurethane tube home until it bottoms, and the stainless spring gasket plus the POM chuck grip it against the NBR O-ring. Press the release ring square into the body and the tube frees off. This is the resin spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, temperature -20 to +70 C and vacuum down to -750 mmHg (10 Torr).

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 PEG10-8 Is Used
Control panel pneumatic manifold
A 10 mm trunk feeding a panel-mounted valve manifold often splits to two 8 mm legs for twin-acting cylinders; the PEG10-8 makes that split in one fitting behind the cabinet wall instead of stacking a straight reducer onto a plain union tee.
Pick-and-place gantry tooling
On a Cartesian pick-and-place head, a single 10 mm supply from the linear axis can tee into 8 mm lines serving the gripper and the blow-off nozzle, keeping the drop weight low and the number of joints at the moving end to one.
Packaging machine air distribution
Cartoning and shrink-wrap machines run one larger feeder along the frame and branch down to 8 mm drops at each sealing or tucking station; a different diameter tee at each drop point keeps the plumbing symmetric and serviceable.
Is the Airtac PEG T-Type Concentric Reducing Tee Fitting PEG10-8 the Right Part?
Step down from here and the pair is PEG8-6, which suits 8 mm feeders running 6 mm actuator lines; step up and PEG12-10 carries the same idea one size larger for the main trunk. What changes with each pair is the bore at the branch point, and since AirTAC publishes flow for these fittings only as a characteristic curve, size the tube for the air demand and let the fitting follow the tube. A PEG union tee only makes sense where you genuinely need two smaller legs off one larger feed; if you just need a straight reduction in line, the PG different diameter straight union is the leaner part.
Tube OD must match exactly on every leg. The Dia 8 ways will not hold 5/16 inch tube and the Dia 10 way will not hold 3/8 inch, even though the numbers look close. Use soft nylon or polyurethane only; semi-rigid or thick-walled tube will not seat past the spring gasket.
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 PEG10-8 FAQ
It is a resin one-touch different diameter union tee for Dia 10 mm and Dia 8 mm soft nylon or polyurethane tube, with no port thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, temperature range -20 to +70 C, and it holds vacuum to -750 mmHg (10 Torr). The body is grey as standard; there is no thread, so no PT, G or NPT option exists on this part.
No on both counts. The fitting grips only soft nylon or polyurethane tube whose OD is exactly 8 mm; a 1/4 inch tube (6.35 mm OD) or 5/16 inch tube (7.94 mm OD) will not seal and will blow off under pressure. Rigid or thick-walled tube also fails to seat past the stainless spring gasket. If your circuits mix inch and metric sizes, change at a purpose-made different diameter fitting rather than forcing a near-size pair.
