About the Airtac PHF Tandem Toggle Joint PHF1203D-S
The PHF1203D-S is AirTAC's universal female elbow in the one-touch range, joining a Dia 12 mm soft nylon or polyurethane tube to a 3/8 inch female PT port. Because the thread is female, the fitting bolts straight onto a male stud on the machine side, and the universal elbow head swivels so the tube outlet can be aimed exactly where the hose run needs to go. Push the tube home and the internal chuck grips it under the stainless spring gasket; press the release ring and it slides straight back out.
This is the -S variant, and on the PHF family that means one specific thing: the mounting stud is SUS304 stainless steel. The body stays PBT, here in black because of the D suffix, so do not read this as an all-stainless fitting - that description applies to the PC and POC connectors, not to elbows. Ratings are identical to the standard line: 0 to 1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C.

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 PHF1203D-S Is Used
Solenoid valve island take-off
Screws onto the male 3/8 inch PT stud of a valve manifold on a packaging line and swivels to aim the Dia 12 feed tube clear of adjacent coil bodies.
Wash-prone food plant cylinder feed
On a meat-tray sealing machine, the SUS304 stud gives the port interface a corrosion-resistant contact point while the black PBT elbow routes Dia 12 PU tube down to the gripper cylinder.
Retrofit inside a tight guard
Replacing a fixed elbow on an old bottling machine air drop, the swivel head of the PHF lets the installer set the exact tube direction after mounting instead of re-clocking the port.
Is the Airtac PHF Tandem Toggle Joint PHF1203D-S the Right Part?
Dia 12 is the top of the PHF ladder on a 3/8 inch thread - the prefix offers 6, 8, 10 and 12 mm on this port, so PHF1003D-S is the step down and there is no larger tube on 3/8 inch in this family. If your circuit grows past Dia 12 you move thread, not tube: PHF on 1/2 inch still supports 8, 10 and 12 mm, so a PHF1204-D-S keeps the same tube bore on the bigger port. Match the port you actually have - a female thread needs a male stud or nipple on the machine, not another male fitting. And whatever you buy, the tube OD must match the fitting exactly: a Dia 12 chuck will not seal or hold 1/2 inch tube, and the two sizes are close enough to fool a casual glance.
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 PHF1203D-S FAQ
It is a universal female elbow taking Dia 12 mm soft nylon or polyurethane tube into a 3/8 inch female PT thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, negative pressure down to -750 mmHg, and temperature range -20 to +70 C. The -S suffix adds a SUS304 stainless stud; the body remains PBT in black, and none of the pressure or temperature figures change versus the standard part.
No. On PHF, PL and the other shaped elbows, AirTAC fits a SUS304 stud while the body stays PBT - only the PC and POC straight connectors get a full SUS304 body. If your corrosion concern is at the thread interface, this part covers it; if you need an all-stainless body, that is a different prefix. The swivel function, tube gripping and release behaviour are otherwise unchanged.
