About the Airtac PHF Tandem Toggle Joint PHF801D-S
PHF801D-S is an AirTAC PHF series universal female elbow: a one-touch fitting that grips Dia 8 mm soft nylon or polyurethane tube on one leg and presents a 1/8 in PT female thread on the other. Unlike the fixed PL male elbow, the PHF thread is free to swivel, so you can tighten the connection first and then rotate the tube leg to whatever angle the pipework needs. To make the joint, push the tube straight into the chuck until it bottoms; the stainless spring gasket and NBR O-ring seal it, and pressing the release ring frees the tube again.
This is the resin/brass spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The D suffix orders the black body. On this -S variant the elbow body remains PBT while the 1/8 in threaded stud is SUS304, placing corrosion-resistant metal exactly where the fitting meets the port; pressures, temperatures and every dimension match the standard PHF801D.

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 PHF801D-S Is Used
Clocking an elbow behind a machine guard
On a packaging machine with 1/8 in PT ports hidden behind fixed guarding, thread the PHF801D-S home first and swing the Dia 8 tube exit to the angle the guard allows - a fixed PL elbow cannot be re-oriented after tightening.
Salt-air marine actuator lines
Deck winches and hatch cylinders on boats live in salt fog; the SUS304 stud at the port resists corrosion where a plain brass stud would weep, while Dia 8 polyurethane tubing runs flexibly out to the actuator.
Corrosive-mist air drop in a plating shop
Step a Dia 8 polyurethane drop off a 1/8 in female port on a small manifold above plating tanks, where acid mist makes the stainless threaded stud a worthwhile upgrade over the standard PHF801D.
Is the Airtac PHF Tandem Toggle Joint PHF801D-S the Right Part?
On the 1/8 in rung of the PHF ladder, Dia 8 is the top step: the only smaller part on this thread is PHF601 (Dia 6 tube), which suits lighter pilot lines and small vacuum cups, while Dia 10 or 12 tube forces a move to a 1/4 in or 3/8 in port such as PHF1002 or PHF1202. Step down to PHF601 where space is tight, and step up only when the actuator's air demand genuinely outgrows what an 8 mm bore can carry.
Match the thread to the port you actually have: this is a female 1/8 in PT thread that screws down over a male stud or plug, so the mating male thread brings the sealant - on M5 ports a sealing gasket does that job instead. The tube OD must match exactly, because a Dia 8 chuck holds 8 mm tubing only and will not seal on 1/4 in or 5/16 in imperial tube.
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 PHF801D-S FAQ
It is a universal female elbow for Dia 8 mm tubing with a 1/8 in PT female thread and a black (D) body. Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. Applicable tubing is soft nylon or polyurethane. The -S makes the threaded stud SUS304; every pressure, temperature and dimension figure is identical to the standard PHF801D.
No. In the PHF family the -S affects only the stud: the elbow body stays PBT and the part's dimensions match the standard version exactly. AirTAC publishes no corrosion class, surface finish or food or medical certification for the stainless line, so it should be chosen for its corrosion resistance at the port, not specified against a certificate.
