About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB401
The PEB401 is an AirTAC PEB male branch tee, the smallest push-to-connect branch fitting in the resin one-touch range. It takes Dia 4 mm soft nylon or polyurethane tube and screws into a 1/8 inch PT male port, with the branch leg leaving at 90 degrees so a third circuit can be fed from a single supply point. To connect, you push the tube straight into the collet until it bottoms out - a stainless spring gasket and the POM chuck grip it against the brass body - and a press on the release ring lets it slide back out.
This is the resin and brass spec profile, not the metal BP line: working pressure 0 to 1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a service window of -20 to +70 C. The 1/8 inch thread arrives with pre-applied sealant, so no additional tape or paste is needed before fitting. Dia 4 is the starting point of the PEB ladder, which makes this part the natural choice where a 4 mm pilot or signal line must split without adapters.

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 PEB401 Is Used
Pilot signal tap on a pneumatic valve manifold
Screw the 1/8 stud into a spare manifold port and branch a 4 mm pilot line to a second valve station, letting one regulator feed two circuits from a single push-in point.
Pressure sensor take-off on a test jig
Tee a 4 mm sensing line off the main air feed at a fixture so a compact pressure switch or gauge reads circuit pressure without disturbing the actuator supply.
Small suction-cup split on an electronics pick-and-place head
Split the vacuum feed at the gantry head: the branch leg feeds a second 4 mm cup line, keeping tubing runs short and the head footprint minimal.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB401 the Right Part?
Dia 4 is the smallest tube PEB makes, so there is no step down - the only step up is PEB601, the same branch tee in Dia 6. Moving to Dia 6 buys more bore for longer runs or higher flow demand, but check that your cylinder, sensor or regulator port still accepts a 4 mm line; a Dia 6 fitting will not grip 4 mm tube. On the thread side, PEB4M5 gives the identical tee with an M5x0.8 stud (which uses a sealing gasket rather than thread sealant), and PEB402 steps the port up to 1/4 inch while keeping the 4 mm tube end. Match the thread to the port you actually have - forcing a 1/8 stud into a 1/4 tapped hole with tape is a leak waiting to happen. If you need the branch to pass through a panel wall instead of a port, a PM bulkhead connector is the right shape, not this 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 PEB T-Shaped Straight Thread Tee Connector PEB401 FAQ
The PEB401 is a PEB male branch tee for Dia 4 mm soft nylon or polyurethane tube with a 1/8 inch PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. Standard colour is grey; the release button is POM and the thread ships with sealant pre-applied.
No. The chuck in the PEB401 is sized for Dia 4 mm tube only - a 6 mm tube will not enter, and a nominal 5/32 inch (4 mm nominal) tube from another standard should still be verified at exactly 4 mm OD with a metric tolerance. For 6 mm lines order PEB601 instead. Soft nylon and soft polyurethane are the approved materials; rigid nylon or metal tube will not seal in a one-touch collet.
