About the Airtac PEG T-Type Concentric Reducing Tee Fitting PEG12-10
The PEG12-10 is an AirTAC PEG different diameter tee, a tube-to-tube one-touch reducer that joins a Dia 12 mm through line to a Dia 10 mm branch in a single moulded body. There is no threaded port here: all three connections push soft nylon or polyurethane tubing straight in. The internal chuck grips the tube wall on insertion and the stainless spring gasket keeps the seal; pressing the POM release ring frees the tube again for rework or re-routing.
It runs on the standard resin one-touch spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The body is PBT over a brass-based construction with an NBR O-ring, and the hyphenated code is AirTAC's own reducer convention - the first number is the main bore, the second the branch. Note also that the -750 mmHg rating means this tee is fully usable on vacuum pick-and-place circuits, not just pressure lines.

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 PEG12-10 Is Used
Packaging machine air drop
On a cartoning or wrapping machine, the 12 mm main runs along the frame and the PEG12-10 branch taps off at 10 mm to feed a gripper or vacuum generator circuit without a separate reducing union plus tee.
Bottling line branch tee
A wash-down bottling hall runs a Dia 12 mm ring main over the filler; this tee branches off at 10 mm to supply the capper's tie-rod cylinders while keeping the tee buried inside the guarding.
Textile machine manifold drop
Weaving and knitting machines distribute air through 12 mm nylon trunk lines; the 10 mm branch of this tee feeds a local cluster of small jets or tension cylinders from one push-in point.
Is the Airtac PEG T-Type Concentric Reducing Tee Fitting PEG12-10 the Right Part?
Step down from this part to PEG10-8 when your main line is Dia 10 and the branch drops to Dia 8 - everything else about the fitting stays the same. There is no larger PEG: Dia 12 is the biggest tube size in this catalogue, so PEG12-10 sits at the top of the reducing-tee ladder. If you need the same 12-to-10 reduction with no branch at all, the PG12-10 straight reducer is the leaner choice.
Remember that tubing must match each port exactly: the two in-line ports take Dia 12 mm tube only, and the branch takes Dia 10 mm only - a Dia 6 or 1/4 in tube will not seal in either port. Check that the 10 mm branch actually feeds what you intend; if the branch serves a smaller actuator, consider stepping again with a PG union reducer downstream rather than forcing an undersized tube into the tee.
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 PEG12-10 FAQ
It is a Dia 12 mm to Dia 10 mm reducing union tee with no threaded port. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it withstands vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C with soft nylon or polyurethane tubing.
No. Each port grips exactly one tube outside diameter: the two through ports take only Dia 12 mm tube and the branch takes only Dia 10 mm tube. For a genuine 10 mm to 10 mm junction use a PE10 union tee, and for other size steps pick the matching hyphenated PEG code such as PEG10-8.
