About the Airtac PH-1 Hex Head Toggle Joint PH603-S
The PH603-S is the SUS304 version of AirTAC's PH universal male elbow, a one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tube to a 3/8 in PT male thread. Because it is a universal elbow, the threaded stud seats into the port first and the elbow body then swivels to whatever angle the tubing run needs, so you are not forced to bend the tube sideways to line it up. Push the tube home and the internal chuck grips it; press the release ring and it frees again.
On the -S code the stud is SUS304 while the elbow body remains PBT, so treat this as a corrosion-resistant threaded joint rather than a solid stainless part. The ratings are unchanged from the standard resin line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. Every threaded AirTAC part in this catalogue arrives with sealant already on the thread, so the stud is ready to make a sealed joint straight out of the bag.

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 PH603-S Is Used
Wash-down cylinder connection on food conveyors
On a poultry or dairy washing line, the elbow swivels to feed a cylinder port sitting behind a splash guard, and the SUS304 stud stands up to daily caustic rinsing where plated threads would pit first.
Salt-spray actuator lines on marine decks
Feeding a hatch or winch actuator on a boat deck, the PBT body with SUS304 stud shrugs off salt-laden air, and the swivel action copes with the deck angles that a fixed elbow cannot.
Rinsing stations in a plating or dye house
At a textile dyeing or electroplating rinse station, the elbow points the Dia 6 drop line exactly at the work area while the threaded joint stays out of the chemical splash zone.
Is the Airtac PH-1 Hex Head Toggle Joint PH603-S the Right Part?
Within the PH prefix, a 3/8 in thread is offered in Dia 6, 8, 10 and 12, so Dia 6 is the smallest bore you can put on this thread size; the next step up is PH803-S, which buys a heavier flow path for the same port. If your tube is Dia 4, you need to drop the thread to 1/8 in or M5 instead, because no Dia 4 PH part exists in 3/8 in.
Match the 3/8 in stud to a 3/8 in PT port or a compatible sealed boss, and let the universal joint absorb misalignment rather than the tube. The tube OD must match exactly: a Dia 6 chuck will not seal or hold 1/4 in (6.35 mm) imperial tube, and the two sizes are not interchangeable despite looking 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 PH-1 Hex Head Toggle Joint PH603-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It joins Dia 6 mm soft nylon or polyurethane tube to a 3/8 in PT male thread, with a SUS304 stud and PBT elbow body, POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
No. In the PH, PL, PEB, PED, PYB, PZB, PHF, PHW and PKD families, -S means the threaded stud is SUS304 while the body stays PBT. The all-stainless-body treatment applies only to the PC and POC straight connectors. Pressure, temperature and dimensions are identical to the standard PH603, so you gain corrosion resistance at the port without changing any other specification.
