About the Airtac PE Tee Connector PE8
The AirTAC PE8 is a union tee from the PE push-in range: a fully symmetric three-way fitting with a Dia 8 mm socket on every leg and no external thread at all. Because there is no stud and no port thread, it needs no sealant and no wrench - it simply splices a branch into a run of 8 mm tubing wherever the run already exists. This is the standard resin profile: 0-1.0 MPa (0-10 kgf/cm2) working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C.
To make the joint, cut the soft nylon or polyurethane tube square, push it into a leg until it bottoms, and the POM chuck inside grips the OD while the stainless spring gasket seals against it. Press the release ring toward the body and the tube comes free again. The body is PBT over an aluminium-alloy guide with an NBR O-ring; grey is standard and the D suffix gives a black body on this series. The tee is symmetric, so any leg can be the inlet and the other two become outlets.

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 PE Tee Connector PE8 Is Used
Robot end-of-arm tooling branch
On a FANUC or ABB pick-and-place gripper, one air drop often feeds two suction cups or grippers. An equal tee in Dia 8 tube splits the supply at the wrist, and the released-and-re-cut joint makes tooling changes fast between product changeovers.
Control cabinet instrumentation drop
A pressure switch and a small regulator on a machine control panel can share one drop from the main airline. The PE8 taps the branch inside the enclosure without adding a threaded port to the manifold, and the PBT body keeps the splice light and compact behind the wiring duct.
Packaging line air nozzle split
Carton-sealing and labelling heads frequently run two short air-blast nozzles off a single Dia 8 supply. A union tee at the nozzle base splits the feed evenly, and the NBR-sealed push-in joints tolerate the -20 to +70 C range found near sealing stations.
Is the Airtac PE Tee Connector PE8 the Right Part?
PE8 sits mid-ladder: PE6 steps the branch down to Dia 6 tubing for lighter lines, while PE10 opens to Dia 10 for runs feeding larger actuators or longer circuits. Stepping up in bore lowers resistance through the branch, which matters on long tube runs and tee points close to a cylinder port. If instead you need to thread a branch off a valve manifold or a component port, the correct shape is the PED male run tee or PEB male branch tee, not the PE. Whatever you pick, tube OD must match the socket exactly - a Dia 8 PE8 socket will not grip or seal 1/4 inch (6.35 mm) tube even though the two look close.
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 PE Tee Connector PE8 FAQ
The PE8 is a Dia 8 mm union tee - all three legs take 8 mm OD soft nylon or polyurethane tube. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure is 1.5 MPa, vacuum rating is -750 mmHg (10 Torr), and temperature range is -20 to +70 C. It is a resin-body fitting with POM chuck and release ring, aluminium-alloy guide, stainless spring gasket and NBR O-ring seals.
No. One-touch sockets are sized to a single tube OD; the chuck fingers and spring gasket in the PE8 are made for an exact Dia 8 mm OD and will not grip or seal 5/16 inch (7.94 mm) tube. Keep the whole run 8 mm, or use a PG different-diameter union to step sizes where a genuine change of bore is intended.
