About the Airtac PEB T-Shaped Straight Thread Tee Connector PEB4M5D-S
The PEB4M5D-S is an AirTAC PEB male branch tee in the stainless -S variant, joining Dia 4 mm soft nylon or polyurethane tube to an M5x0.8 male thread, finished in black. It pushes a branch leg off an existing run without cutting the supply line: press the tube home and the stainless spring gasket inside the chuck grips it, press the POM release ring and it frees again. The M5 stud arrives with a sealing gasket rather than pre-applied thread sealant, so it seats straight into small instrument and valve ports.
This is the resin one-touch spec profile, not the metal line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. Because the code ends in -S, the stud is SUS304; the tee body stays PBT with POM release parts, an aluminium-alloy guide and an NBR O-ring. AirTAC publishes no new ratings for the stainless variant, so every figure above is unchanged from the grey standard part.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PEB4M5D-S Is Used
Laboratory analyzer branch drop
Tee off a Dia 4 supply run inside a compact diagnostic or fluid-handling analyzer, branching to a small pilot actuator on an M5 valve port without disturbing the main line.
PCB dispensing head pickup
Pick a clean air feed for a conformal-coating or glue dispensing head from a 4 mm nylon run; the SUS304 stud resists flux and cleaning-solvent attack around the electronics line.
Clamping jig air distribution
Split a single 4 mm feed into two legs on a small assembly jig so a toggle clamp and a blow-off nozzle share one M5-threaded source port.
Is the Airtac PEB T-Shaped Straight Thread Tee Connector PEB4M5D-S the Right Part?
Dia 4 is the smallest tube this family makes, so there is no step down. The only M5 neighbour is Dia 6 (PEB6M5D-S): the bore opens up for shorter, less restrictive branch runs, at the cost of a taller tee on an M5 foot. If you need a 1/8in port instead, that is a different SKU on the same ladder (PEB401 and up), which also unlocks tube sizes up to Dia 12.
Check the port before ordering: M5x0.8 threads on valves, sensors and manifold blocks seal with a gasket face, and this stud supplies one. Tube must match exactly - a Dia 4 chuck will not reliably hold 5/32in or 6 mm tube, even though both 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 PEB T-Shaped Straight Thread Tee Connector PEB4M5D-S FAQ
It is an AirTAC PEB male branch tee for Dia 4 mm tube with an M5x0.8 thread, in black with a SUS304 stud. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It takes soft nylon or polyurethane tube and seals on the M5 stud with a supplied gasket. Thread standard is PT across this catalogue.
No. On PEB branch tees the -S upgrade moves the male stud to SUS304; the tee body remains PBT, with the same POM release button, aluminium-alloy guide and NBR O-ring as the standard part. AirTAC publishes no separate pressure, temperature or corrosion class for the stainless variant, and only the straight PC and POC connectors get a full 304 body in this family.
