The AirTAC Airtac PHF Tandem Toggle Joint PHF602D is a genuine universal female elbow for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PHF602D is an AirTAC PHF universal female elbow in black. It joins Dia 6 mm soft nylon or polyurethane tube to a 1/4" PT female port, and the head of the elbow can be rotated on its axis before final tightening so the outlet faces exactly the direction the tube run needs. It belongs to the resin one-touch range: 0 to 1.0 MPa working pressure, vacuum down to -750 mmHg, 1.5 MPa proof pressure, and a service window of -20 to +70 C.
Connection is genuinely one-touch. Push the Dia 6 tube into the chuck until it bottoms and the stainless spring gasket and NBR O-ring seal around it; the POM chuck grips under pressure. Pressing the release ring frees the tube again for rework. The female thread receives a male stud from the machine side, and the thread arrives from AirTAC with sealant already applied, so no extra tape or paste is needed at assembly.

On a rotary indexing table, air ports rotate through the cycle and rarely leave a straight approach to the Dia 6 tube. The pivoting PHF head lets the drop leg run vertically regardless of where the port faces.
Inside a cartoning machine guard, a rigid female-threaded port often points toward the frame wall. A female universal elbow turns the outlet away from the wall so a Dia 6 tube can be pushed in with fingers and released later without removing the fitting.
Loom and spinning frames use compact Dia 6 drops to individual jets and tensioners. Routing with a rotating elbow at each port keeps the nylon line off moving yarn paths while leaving the thread face-sealed against the frame manifold.
On the 1/4" thread, PHF supports only Dia 6, Dia 8 and Dia 10 tube, so this Dia 6 version is the smallest tube that pairs with 1/4" in this series. Step up to PHF802 when the circuit feeds a larger-bore actuator that needs more volume per stroke; drop to PHF601 if the port is only 1/8" and the run stays Dia 6. Whichever you pick, the tube OD must match the fitting exactly - Dia 6 is not a home for 1/4" or 8 mm tube, and an undersized tube will blow off under pressure.
Choose PHF over a fixed PL elbow when the approach angle to the port is awkward: the rotating head lets you align the outlet after the fitting is seated, which a moulded elbow cannot do. If the port is female and you need a male stud instead, the PH series in Dia 6 covers that case.
Quick checklist
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. This SKU is the Dia 6 mm tube size with a 1/4" PT female thread, in the black D colour option, from the resin one-touch family with POM chuck, aluminium guide, stainless spring gasket and NBR O-ring.
If the port on your manifold or cylinder head is already a male stud with sealant, a female elbow seals directly onto it without an extra adapter, saving height and a joint. The PHF head then rotates so the Dia 6 outlet aligns with your tube routing before you snug it down - the thread carries sealant from the factory, so no additional sealing material is required.
