The AirTAC Airtac PHF Tandem Toggle Joint PHF802 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 PHF802 is an AirTAC PHF universal female elbow, a swivelling one-touch elbow whose 1/4in PT female thread mates straight onto a male port on the machine, so no separate male stud or nipple is needed. It accepts 8 mm outside diameter soft nylon or polyurethane tubing on the tube end.
Push the tube fully home and the internal chuck grips it under pressure; press the release ring to free it. This is the resin and brass profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The universal head swivels so the elbow body can be aimed after the thread is torqued down, and the PT thread arrives from AirTAC already coated with sealant, ready to install without extra tape or paste.

On a compact air press or clamping cylinder where the 1/4in port faces a guard rail, the swivelling elbow points the 8 mm run along the frame instead of straight into the obstruction.
Feeding gripper or sealing cylinders on a horizontal flow-wrapper, the female 1/4in thread lands directly on the valve manifold stud and the elbow swings to match the tube dress.
When re-piping an older machine with unknown port clocking, the universal head absorbs the angle error, letting the installer finish the 8 mm line neatly without bending fittings or adding adapters.
On the 1/4in PT thread, the PHF ladder runs Dia 6, Dia 8 and Dia 10. Dia 8 is the middle step: step down to PHF602 for lighter lines feeding small actuators or sensors, step up to PHF1002 when flow demand rises on a main drop. Note that at 1/8in thread this family tops out at Dia 8, so if you need a 10 mm or 12 mm tube you must move to the 3/8in or 1/2in PHF sizes instead.
Choose PHF over the fixed PL elbow when the exact approach angle is unknown at design time or the port sits at an awkward clocking position; the swivel takes up the mismatch. The female thread also saves stack length compared with a male elbow plus adapter. Tubing outside diameter must match exactly - this chuck holds 8 mm tube only, not 5/16in or any close substitute.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Tube size is Dia 8 mm soft nylon or polyurethane; thread is 1/4in PT female. This is the resin/brass one-touch profile, not the 0.9 MPa metal line.
The PL elbow body is fixed at 90 degrees to its thread, so the port clocking dictates the tube direction. The PHF head swivels on the thread, letting you aim the elbow anywhere on the sphere after installation - useful when ports land at odd angles. On this 1/4in version the female thread also mates directly to a male port with the factory-applied sealant, removing the need for a separate male adapter.
