About the Airtac PHF Tandem Toggle Joint PHF603
The PHF603 is an AirTAC PHF universal female elbow, a swivel-type one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tube to a 3/8" PT female port. Push the tube fully home and the internal stainless spring gasket and chuck grip it under the ferrule; press the POM release ring and the tube frees for rework. Because the elbow pivots, you thread the body in first, then rotate the head so the tube exits exactly where the machine needs it - no shimming, no bent tube.
This is a resin/brass fitting, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg, and a service range of -20 to +70 C. The 3/8" stud arrives with thread sealant already applied, so the female port seats without a coil of tape. Standard body colour is grey; the release button, chuck and guide are POM and aluminium alloy with an NBR seal.

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 PHF603 Is Used
Bottling filler carousel
A 3/8" tapped port on the rotary valve manifold feeds a Dia 6 PU drop line to each filler nozzle actuator; the swivel head lets the line exit vertically even where the port face is angled.
Robot gripper wrist block
On a pick-and-place end-of-arm tool, the wrist block's 3/8" female supply port steps down to a 6 mm line serving the gripper valve, with the elbow rotated to clear the cable dress.
Analytical instrument cabinet
Inside a lab analyser, a 3/8" bulkhead port on the pneumatic chassis steps to Dia 6 nylon tubing routed to a small pilot valve, where the swivel avoids kinking the tube behind the shroud.
Is the Airtac PHF Tandem Toggle Joint PHF603 the Right Part?
On the PHF ladder, Dia 6 is the smallest tube offered with a 3/8" thread - the row runs 6, 8, 10, 12 - so PHF803 is the only step up from here. That combination pairs a generous port with a slim bore: handy when the port is fixed but the airflow demand is modest, since the 6 mm bore sets the capacity regardless of port size. If your port is smaller, the same Dia 6 tube exists as PHF602 (1/4") and PHF601 (1/8").
Choose PHF over the plain PL male elbow when the port is tapped female and the tube run needs a swivel to line up. Tube OD must match exactly: a Dia 6 fitting will not hold 1/4" (6.35 mm) tube, and the seal relies on the full wall gripping the chuck.
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 PHF603 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability to -750 mmHg (10 Torr), and an operating temperature range of -20 to +70 C. The fitting joins Dia 6 mm tube to a 3/8" PT female thread and is part of AirTAC's resin/brass one-touch range for soft nylon or polyurethane tubing.
No. AirTAC ships this fitting with sealant pre-applied to the thread, and M5 sizes in the family use a sealing gasket instead. That is one reason the swivel design matters here: you torque the body home with the sealant doing its job, then orient the elbow head afterwards without unwinding the thread.
