The AirTAC Airtac PEB T-Shaped Straight Thread Tee Connector PEB1002 is a genuine male branch tee for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PEB1002 is an AirTAC PEB male branch tee, a push-in fitting that splits one Dia 10 mm tube line into two: the main run passes straight through the tee, and a 90 degree branch with a 1/4 inch PT male thread taps off at right angles. That through-run geometry is what separates a branch tee from a male run tee (PED), where the threaded leg sits in line instead of to the side. To connect, push the soft nylon or polyurethane tube straight into the chuck until it bottoms out - the stainless spring gasket grips the tube wall and the POM release ring unlocks it again when you need to rework the circuit.
This is the resin and brass one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg, and a service range of -20 to +70 C. The body is PBT with a brass threaded stud, the stud arrives with sealant already applied on the thread, and the standard colour is grey (order the D suffix for black). AirTAC publishes no flow curve values for these fittings, only characteristic curves - capacity follows the 10 mm bore, the largest tube this thread takes.

On a palletising cell, the Dia 10 trunk running along the frame can pass straight through the PEB1002 while the 1/4 inch branch drops to a box-clamp cylinder mounted at 90 degrees to the main line.
A rotary indexing table needs air delivered radially: the branch stud screws into the manifold face and sends a Dia 10 feed out to the turntable grippers without adding a separate junction block.
On a compact analytical or dosing skid, the through-run keeps the main Dia 10 supply unbroken along the frame while the right-angle branch feeds a small pneumatic valve island off a tapped 1/4 inch port.
You are on the middle-upper rung of the PEB ladder at 1/4 inch thread. Step down to the PEB802 (Dia 8 tube) when the line feeds smaller actuators and you want a cheaper, slimmer tube; step up to the PEB1202 (Dia 12) when the branch serves a large-bore cylinder where pressure drop through a narrow bore would matter. Both exist on the same 1/4 inch thread. If the port is smaller, a PEB101 keeps Dia 10 tube on a 1/8 inch stud; if the port is a 3/8 inch hole, the PEB1003 is the mate. Thread the stud into a PT port with the pre-applied sealant doing the sealing - a 1/4 inch male stud will not seat properly in an NPT or parallel port.
Remember the tube rule: Dia 10 means Dia 10. A 3/8 inch (9.5 mm) tube will slip under the chuck and blow off under pressure, so stick to true 10 mm soft nylon or polyurethane.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr), operating temperature -20 to +70 C. The fitting accepts Dia 10 mm soft nylon or polyurethane tube on all three legs and carries a 1/4 inch PT male thread on the branch stud. Body is PBT with a brass stud, POM release ring, stainless spring gasket and NBR O-ring; grey is standard.
No. AirTAC rates PEB fittings for soft nylon and polyurethane tubing only. Hard PE will not deform enough for the chuck and spring gasket to bite, which is the usual cause of a push-in joint weeping or blowing off at pressure. Also note the branch stud is PT tapered - on a parallel (G) port you would need a different thread form, and this catalogue documents PT only.
