About the Airtac PH-1 Hex Head Toggle Joint PH1204D-S
The PH1204D-S is AirTAC's universal male elbow in the stainless -S build: a one-touch fitting that takes Dia 12 mm soft nylon or polyurethane tube into a 1/2in PT male thread, with a swivelling head that can be set to any angle once the stud is screwed into the port. Push the tube home and the internal chuck grips it; press the release ring and it frees again. On the PH family the -S puts a SUS304 stainless steel stud under a PBT body, so the corrosion-critical thread side is stainless while the push-in head stays in the standard glass-filled polymer.
This is the resin one-touch spec profile, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service temperature of -20 to +70 C. The D suffix gives the body in black. The 1/2in PT thread arrives with sealant already applied, and the small M-sizes in the range use a sealing gasket instead, so no extra tape or paste is needed at assembly.

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 PH1204D-S Is Used
Marine deck wash-down actuation
A 1/2in PT tapping on a deck-mounted air manifold feeding a Dia 12 cylinder on a hatch or gangway actuator; the SUS304 stud stands up to salt spray where a brass stud would bloom, and the swivel head lets the drop line sit vertical regardless of stud orientation.
Plating and pickling line air supply
Running Dia 12 polyurethane tube from a supply header down to a lift cylinder beside acid tanks; the stainless stud resists fume attack around the port, and the elbow turns a straight male connector into an angled drop that clears the tank lip.
Chemical dosing skid header drop
On a bunded dosing skid, screwing the stud into the end of a 1/2in PT header and angling the head to route Dia 12 tube down to a diaphragm pump pilot without adding a separate elbow union in the line.
Is the Airtac PH-1 Hex Head Toggle Joint PH1204D-S the Right Part?
On the PH ladder the 1/2in thread carries Dia 8, Dia 10 and Dia 12 tube, so PH1204D-S is the largest tube in this thread row - there is no step up. Stepping down, PH1004-S runs Dia 10 tube on the same 1/2in port; you lose bore, which matters most on long runs or big-bore cylinder supply where flow capacity scales with the tube, not the fitting. If your port is 3/8in instead, Dia 12 is still available on that row as PH1203-S, so you rarely have to sacrifice the tube size to match the port.
The universal head is the reason to pick PH over a fixed PL elbow: set the outlet angle after fitting the stud, which saves a second fitting wherever the tube must drop vertically off a horizontal port. Match the tube OD exactly - Dia 12 is a metric size and will not hold 1/2in imperial hose, however close the numbers look.
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 PH1204D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It joins Dia 12 mm soft nylon or polyurethane tube to a 1/2in PT male thread, with a SUS304 stud and PBT body. The -S stainless build carries exactly the same ratings as the standard PH1204D.
Both swivel, but PH ends in a male 1/2in PT thread that screws into a port or manifold, while PHF ends in a female thread that screws onto a male stud or nipple. Pick PH1204D-S when the port is tapped female; the SUS304 stud is what meets the corrosive environment, and the sealant pre-applied to the PT thread seals the joint at assembly.
