The AirTAC Airtac PHW F Thread Swivel Tee Fitting PHW602 is a genuine double universal male elbow for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PHW602 is an AirTAC PHW double universal male elbow: a one-touch push-in fitting with a 1/4" male PT thread on one end and a Dia 6 mm tube socket on the other, joined by two swivel joints. Because the fitting articulates in two planes, the tube can enter from an angle that a fixed PL elbow cannot reach, and the male thread can be screwed into the port at whatever clock position the sealant needs. Push the tube home and the stainless chuck grips it; press the release ring to free it.
This is the resin and brass one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service temperature of -20 to +70 C with soft nylon or polyurethane tube. The body is PBT on a brass stud, with a POM release button, aluminium-alloy guide and NBR O-ring. Note that the PHW range starts at 1/8" thread - there is no M5 version in this series.

Robotic weld cells position clamp cylinders at odd angles inside the fixture frame. The double universal joint lets 6 mm PU tube swing into the cylinder port from two directions, avoiding the tight bend radius that kinks small tube.
On a rotary indexing table, the pneumatic feed to the rotary actuator turns with the table. A PHW602 at the port takes up the changing approach angle in both planes while the chuck holds the 6 mm tube under vibration.
Packaging machine guard interiors leave little straight run between valve manifold and ejector cylinder. The two swivel sections of this elbow steer the 6 mm nylon tube around corner posts where a fixed-angle elbow would force an over-bend.
PHW602 is the Dia 6 tube entry on the 1/4" thread rung of the PHW ladder, which supports Dia 6, 8 and 10 at this thread. Stepping up to PHW802 buys you a Dia 8 bore feeding larger actuators; there is no Dia 4 option at 1/4" on a PHW - the smallest PHW tubes (Dia 4) only come on the 1/8" thread, so if you need Dia 4 with double-universal articulation you move to the PHW4-01 instead. For the same Dia 6 tube on a smaller port, PHW601 keeps the shape but drops the thread to 1/8".
Match the 1/4" thread to the port, not the tube: the thread arrives with sealant pre-applied, so no extra tape is needed on a PT port. Choose a PHW over a plain PL elbow when the tube must approach from an oblique angle in two directions; choose a PM bulkhead when the line has to pass through a panel wall instead. The tube OD must match exactly - this socket will not hold 1/4" (6.35 mm) tube, only genuine 6 mm OD soft nylon or polyurethane.
Quick checklist
It joins Dia 6 mm soft nylon or polyurethane tube to a 1/4" male PT thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it handles vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the service temperature range is -20 to +70 C. The body is PBT with a brass stud, POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
Both the threaded stud and the tube socket rotate relative to the centre body, so you can align the 1/4" thread for sealing and then swing the tube entry to the angle the run needs - something a fixed PL elbow cannot do. Sealing relies on the pre-applied thread sealant on the stud, not on the swivels, so the joints stay dry on the outside once assembled. Remember the tube must be exactly 6 mm OD; the socket will not grip 1/4 inch (6.35 mm) tube.
