The AirTAC Airtac PHF Tandem Toggle Joint PHF802D is a genuine universal female elbow for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PHF802D is an AirTAC PHF universal female elbow, a swivelling 90 degree fitting that joins Dia 8 mm soft nylon or polyurethane tube to a 1/4in female PT thread. Because the thread is female, it screws down over a male stud, a cylinder head port or a threaded manifold boss, and the universal joint lets you rotate the body to point the tube run exactly where it needs to go before you lock the position.
To connect, push the tube straight into the chuck until it bottoms out - the stainless spring gasket and POM chuck grip it against the NBR O-ring. Pressing the release ring frees the tube again. This is the resin one-touch profile, not the metal BP line: working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa, and a service range of -20 to +70 C. On this PHF body the D suffix means the whole body is moulded in black, not just the release button.

Screwed onto the male head port of an indexing cylinder under a low sheet-metal guard, the swivel elbow lets the Dia 8 tube leave at the angle that clears the rotating table without kinking.
On looms and spinning frames where air lines follow the machine frame, the black body and adjustable outlet angle let the 8 mm tube track the rail and turn corners at each guide bracket.
Threaded onto a male manifold stud on a cartoner's valve bank, the female elbow drops a Dia 8 branch down to a glue-head or flap-folding actuator set at any radial angle.
On a 1/4in female thread, the PHF ladder offers Dia 6, 8 and 10. Stepping down to the Dia 6 version (PHF602) suits lighter pick-off lines and smaller actuators; stepping up to Dia 10 (PHF1002) moves more volume to bigger cylinders at the same port size. On the Dia 8 tube side, this thread has a neighbour too: the same 8 mm tube is also made on 1/8in (PHF801) and 3/8in (PHF803) female threads, so match the fitting to the port you actually have.
Pick a PHF rather than a fixed PL elbow when the exit angle must be set on installation - the swivel lets you square the tube run to a frame rail after the thread is tightened. The tube OD must match exactly: a Dia 8 fitting will not seal on 1/4in (6.35 mm) imperial tube, and no inch-size equivalent exists in this metric catalogue.
Quick checklist
It is a Dia 8 mm tube by 1/4in female PT thread universal elbow. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum rating is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tube and comes in a black body.
A fixed PL elbow points one way only, so the thread and the tube exit are locked together. On this PHF, the body swivels on the threaded stud, letting you orient the 8 mm tube outlet after installation - useful when a guard panel, bracket or adjacent hose dictates the exit direction. The female 1/4in thread drops over a male port, and the threaded interface arrives with sealant already applied.
