About the Airtac PHF Tandem Toggle Joint PHF1203-S
The PHF1203-S is an AirTAC PHF universal female elbow, a one-touch fitting that takes Dia 12 mm soft nylon or polyurethane tube into a 3/8 inch PT female thread. Push the tube straight in and the stainless spring gasket plus chuck ring grip it against the POM seat; press the release button and the tube comes straight back out. Because the thread is female, the elbow screws down onto a male PT spigot and the joint stays sealed at the thread face rather than on the body.
This is the -S variant: the stud is SUS304 stainless steel, which is the part the thread load and the port environment see. The elbow body itself remains PBT with a POM release button and NBR O-ring, exactly like the standard PHF1203. Every rating carries over unchanged from the resin line: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. AirTAC publishes no different rating for the stainless version.

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 PHF1203-S Is Used
Pick-and-place robot arm
Feeding a Dia 12 line to a large pneumatic gripper on a robotic arm: the female elbow rotates on its thread seat, so the tube exits down the arm axis even when the wrist port lands at an angle.
Wash-down reject station on a packaging conveyor
Air drop to a pusher cylinder on a food-grade wash-down conveyor, where the SUS304 stud at the port resists corrosion while the PBT elbow body sits clear of the spray line.
Manifold valve outlet on a press line
Taking the 3/8 inch female outlet of a control manifold down to a Dia 12 feed for a clamping actuator, with the swivel elbow pointed along the frame rail instead of into the guard.
Is the Airtac PHF Tandem Toggle Joint PHF1203-S the Right Part?
Dia 12 mm is the top of the 3/8 inch ladder on the PHF prefix. One step down is the PHF1003, the same 3/8 inch female elbow for Dia 10 tube, which suits smaller actuator ports and lets you keep a common thread across a machine while stepping the bore. For more bore, step the thread instead: the PHF1204 carries Dia 12 on a 1/2 inch PT female thread. Note that 1/4 inch stops at Dia 10 on the PHF row, so there is no smaller-thread option at this bore - 3/8 inch is the entry point for Dia 12 here.
Match the tube OD exactly: this chuck grips 12 mm tube only and will not seal on 1/2 inch (12.7 mm) imperial tube. Choose the universal female elbow shape when the port points sideways to the tube run and you need the fitting to swivel into alignment after tightening instead of fighting the body square.
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 PHF1203-S FAQ
It is an AirTAC PHF universal female elbow joining Dia 12 mm soft nylon or polyurethane tube to a 3/8 inch PT female thread, with a SUS304 stud. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure goes to -750 mmHg, proof pressure is 1.5 MPa and the temperature range is -20 to +70 C. Tube bore, not the fitting, is what sets flow capacity.
No. On the PHF family, -S means the stud is SUS304 stainless steel; the elbow body stays PBT with a POM release button and NBR O-ring, and the dimensions match the standard PHF1203 exactly. The pressure, vacuum, proof and temperature ratings are identical to the standard version - stainless changes corrosion behaviour at the port, not the ratings.
