About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1203D
The PEB1203D is an AirTAC PEB male branch tee, the fitting you use when a Dia 12mm tube line has to feed a threaded port at 90 degrees while the through-line continues unbroken. Unlike a run tee, the branch outlet is the perpendicular leg, so the main flow path stays straight through the body. This version is the D configuration: on the PEB series the black suffix changes the body colour itself, not just the release button, which matters when you are matching a machine's colour scheme or making air drops visually distinct from other services.
It runs on the resin/brass one-touch spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C with soft nylon or polyurethane tubing. To make the connection, push the tube squarely into the chuck until it bottoms out; the stainless spring gasket and POM chuck grip it, and pressing the release ring frees it again. The 3/8in PT thread arrives with sealant already applied, so it seals on assembly without extra tape or compound.

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 PEB T-Shaped Straight Thread Tee Connector PEB1203D Is Used
Palletizer robot dress-pack air drop
On a palletizing cell's 12mm dress-pack main, a PEB1203D teed at the wrist feeds the gripper cylinder through its 3/8in port without cutting the supply line that continues to the next axis.
Air knife branch on a bottling conveyor
Bottling lines run a 12mm header along the conveyor frame; a branch tee at the 3/8in thread of an air knife manifold taps each station while the header carries on to the next nozzle block.
Press-side air drop in a dark-painted cell
In a stamping press cell with black service lines, the black-bodied PEB1203D branches a Dia 12mm drop off the overhead ring main down to the part-blow-off solenoid, keeping the air circuit visually consistent with the rest of the install.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB1203D the Right Part?
Dia 12 is the top of the PEB tube ladder, so the only tube step available is down to PEB1003 (Dia 10 in the same 3/8in thread), which suits lighter lines and slightly smaller cylinders; there is no Dia 14 or 16 in this catalogue. On the thread side you have PEB1202 (1/4in PT) and PEB1204 (1/2in PT) both in Dia 12, so match the port you are threading into rather than upsizing for safety - an oversized thread on a small port wastes envelope and often cannot seat cleanly. If you need the branch in-line with the run instead of perpendicular, order the PED male run tee in the same sizes.
Remember the tube OD must match the fitting exactly: a Dia 12mm PEB will not grip 1/2 inch hose, and no adapter inside the fitting restores that. Check the interface table for the whole prefix before quoting alternatives - the PEB ladder for 3/8in thread runs 6, 8, 10 and 12mm only.
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 PEB T-Shaped Straight Thread Tee Connector PEB1203D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. This SKU joins Dia 12mm soft nylon or polyurethane tube to a 3/8in PT male thread. The body is the black D-colour variant, and the thread arrives with sealant pre-applied.
In a PEB, the threaded outlet is the perpendicular branch leg and the two tube ends form the straight through-path. In a PED, the threaded outlet sits on the run itself, so flow passes through it in line with one tube leg. Pick PEB when the main line must continue unobstructed and the port is a side take-off; pick PED when the threaded port sits in the main flow path. Both share the same pressure, vacuum and temperature ratings.
