The AirTAC Airtac PHW F Thread Swivel Tee Fitting PHW601D 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 PHW601D is an AirTAC PHW double universal male elbow, a one-touch fitting that connects Dia 6 mm soft nylon or polyurethane tubing to a 1/8 in PT male port. Push the tube home and the stainless spring gasket plus the chuck grip it firmly; press the POM release ring and it frees again. What sets PHW apart from the single universal PH is the second swivel: the tube end articulates independently of the thread end, so the line can leave in a different plane than the port faces.
This part follows the resin and brass one-touch profile, not the metal BP line: 0-1.0 MPa working pressure, 1.5 MPa proof, -750 mmHg vacuum and -20 to +70 C. The D suffix turns the whole body black, not just the release button, which helps where grey fittings vanish against dark machine guards. The thread arrives with sealant pre-applied, so no tape is needed. One quirk of the series: the PHW ladder starts at 1/8 in and offers no M5, unlike its siblings PH and PHF.

When the cylinder port faces sideways but the tube run must drop vertically past the tooling, the double universal elbow bends the Dia 6 PU line through two planes without kinking.
Screwed into a 1/8 in manifold outlet, the swivel aims the tube past neighbouring valves while the black body stands out clearly against grey wiring duct.
Gripper ports sit at awkward angles and shift with the arm; a double universal elbow at each 1/8 in port lets Dia 6 nylon tube leave cleanly instead of taking a sharp side load.
Step down to PHW401 (Dia 4 on 1/8 in) for thin pilot lines feeding small valves or sensors, or up to PHW801 (Dia 8 on 1/8 in) when the same port has to supply a hungrier actuator and you want the larger bore to cut restriction. If the port itself is bigger, the next thread rung for Dia 6 tube is PHW602 at 1/4 in PT. Match the tube exactly: this chuck grips Dia 6.00 mm and nothing else, so 1/4 in tubing at 6.35 mm will not seal, and forcing it only risks a blow-off.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum capability -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting takes Dia 6 mm soft nylon or polyurethane tube on a 1/8 in PT male thread, and the D suffix marks the black body and release button.
No. 1/4 in tubing measures 6.35 mm outside diameter, while the chuck in the PHW601D is made for exactly Dia 6.00 mm, so the seal will never seat properly. Use genuine Dia 6 mm metric tube, or if rewiring the run is an option, step the whole circuit up to Dia 8 tube with the PHW801.
