About the Airtac PHF Tandem Toggle Joint PHF4M5D-S
The PHF4M5D-S is an AirTAC PHF universal female elbow - a one-touch fitting that joins Dia 4 mm soft nylon or polyurethane tube to an M5x0.8 female thread. The female thread lets the elbow screw onto a male stud or ported boss, and the universal joint pivots so the outlet can be aimed after assembly instead of being locked to the thread direction. The D suffix gives this series a black body, and the trailing -S makes the threaded stud SUS304 stainless steel; the body itself remains PBT, so this is a stainless-stud upgrade rather than a solid stainless fitting.
It uses the resin one-touch spec profile: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -750 mmHg vacuum and -20 to +70 C. Push the tube straight home and the stainless spring gasket plus chuck grip it under the POM release button; press the release ring and the tube frees. The M5 stud arrives with a sealing gasket rather than pre-applied thread sealant, which is how AirTAC handles all M5 sizes in this catalogue.

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 PHF Tandem Toggle Joint PHF4M5D-S Is Used
Miniature cylinder on a pick-and-place head
Dia 4 tube and an M5 port are the classic pairing on small guided grippers and mini cylinders. The pivoting elbow lets the airline leave sideways even when the port faces the mounting plate.
Humid bench and plating-line sensing circuits
The SUS304 stud holds up better than plain brass where the fitting threads into a damp enclosure or splash zone on a plating or wash-prone line, without changing any pressure or temperature rating.
Aiming airline drops inside a tight guard
When the thread direction at the machine port points the wrong way for the tube run, a universal female elbow screws onto the stud and swivels to aim the Dia 4 drop without re-plumbing.
Is the Airtac PHF Tandem Toggle Joint PHF4M5D-S the Right Part?
On the M5 row of the PHF ladder only two tube sizes exist: Dia 4 and Dia 6. This Dia 4 version is therefore the smallest M5 female elbow in the range - there is no M5 option below it. Stepping up gives the PHF6M5, which adds bore for slightly freer flow on the same M5 port. If you can move the thread up instead, the PHF401 takes a 1/8 in PT thread and still accepts Dia 4 tube, giving a stiffer stud for higher assembly torque on the port.
Match the fitting to the port, not the other way round: an M5x0.8 female thread needs a male M5 stud or boss behind it. If the port is tapped female, the PH male universal elbow screws in directly instead. For a pass-through through a panel wall, PMF bulkhead is the right shape, not this elbow. And whatever you pick, the tube OD must match exactly - a Dia 4 one-touch will not seal on 5/32 in or 6 mm tube.
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 PHF Tandem Toggle Joint PHF4M5D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting takes Dia 4 mm soft nylon or polyurethane tube on one side and an M5x0.8 female PT thread on the other, with a SUS304 stud and black PBT body.
No. In the AirTAC one-touch catalogue only the larger PT thread sizes arrive with sealant pre-applied on the stud; M5x0.8 sizes are sealed with a sealing gasket instead. Screw the M5 stud in gently against its gasket rather than wrenching it, and keep the thread face clean so the gasket seats properly.
