About the Airtac PH-1 Hex Head Toggle Joint PH6M5-S
The PH6M5-S is AirTAC's PH universal male elbow in the stainless-stud variant: a one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tube to an M5x0.8 male thread. The elbow head pivots on the male thread, so you can push the tube straight in and then swing the body to whatever angle the route demands - no need to pre-bend the plan around a fixed 90 degree casting. Connection is the usual one-touch action: the tube slides past the POM chuck, which grips it against the stainless spring gasket, and the release collar frees it again when you rework the line.
The -S suffix has a precise meaning on the PH family that buyers should know before specifying: the SUS304 goes into the male stud, while the elbow body remains PBT and the guide stays aluminium alloy. AirTAC does not re-rate the stainless version, so the figures are identical to the grey PH6M5 - 0 to 1.0 MPa working pressure, 1.5 MPa proof, -20 to +70 C and -750 mmHg vacuum. A second detail worth noting: M5 ports on this series seal with a gasket, not pre-applied thread sealant, so the stud seats cleanly into the small tapped ports common on compact actuators.

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 PH-1 Hex Head Toggle Joint PH6M5-S Is Used
Compact gripper ports on a pick-and-place head
Small pneumatic grippers and rotary actuators often carry M5 ports half-hidden beside the mounting face. The swivelling PH6M5-S lets the Dia 6 tube exit at whatever angle clears the gripper jaws, and the SUS304 stud holds up on machines that get wiped down between changeovers.
Air feed to a mini vacuum ejector on a lab fixture
Bench-top pick stations and lab automation commonly run M5-threaded ejectors and jets fed by Dia 6 tube. A fixed elbow often fights the ejector body for space; the universal head rotates after install so the tube can drop vertically past neighbouring sensors.
Coolant-misted zone on a packaging machine frame
Where splash or salt-laden air attacks plated brass studs - packaging machinery near wash steps, or coastal plant - the SUS304 stud of this variant resists the corrosion that seizes ordinary studs into aluminium housings. Ratings are unchanged, so no control-system re-approval is needed.
Is the Airtac PH-1 Hex Head Toggle Joint PH6M5-S the Right Part?
On the PH row, M5 is offered only in Dia 4 and Dia 6, so PH4M5 is the one size below this part and Dia 6 is already the largest bore an M5 stud carries. If your flow demand has outgrown Dia 6, the honest answer is not a bigger M5 fitting - it is keeping the Dia 6 tube and stepping the thread to 1/8 inch (PH6-01), or moving to Dia 8 with PH8-01. Always match tube OD exactly: a Dia 6 chuck will not seal on 1/4 inch (6.35 mm) tube, even though the two look close.
Choose the PH shape over a fixed PL male elbow when the port orientation is awkward or unknown at design time - the swivel lets one part number cover several mounting attitudes. If you actually need a female thread or a tee, that is PHF or PED territory, not a modification of this part.
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 PH-1 Hex Head Toggle Joint PH6M5-S FAQ
Tube connection: Dia 6 mm soft nylon or polyurethane. Thread: M5x0.8 male (PT standard, gasket-sealed at M5). Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), temperature -20 to +70 C. In the -S variant the male stud is SUS304; the elbow body remains PBT. Every figure matches the standard grey PH6M5 - AirTAC does not re-rate stainless parts.
No to both. On the PH family the -S suffix means the stud is stainless steel 304 while the body stays PBT - only the PC and POC straight connectors get a solid stainless body. And the chuck accepts Dia 6 mm tube only: 1/4 inch tube measures 6.35 mm and will not seal. If your tube really is 1/4 inch, look at the Dia 4 or Dia 6 M5 alternative PH4M5 instead, or change the port, not the tube.
