The AirTAC Airtac PHW F Thread Swivel Tee Fitting PHW1004D 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 PHW1004D is an AirTAC PHW double universal male elbow: a one-touch fitting that carries Dia 10 mm soft nylon or polyurethane tube into a 1/2in PT male thread, with two swivel joints either side of the elbow body. Because both ends pivot, the fitting can be set to almost any compound angle, which is what separates it from the fixed PL and PLL elbows in the same catalogue. The D suffix makes this the black version - on the PHW family that changes the whole body colour, not just the release button.
Connection is genuinely one-touch: push the tube straight in and an internal stainless spring gasket plus the chuck jaws grip it against pressure; press the release ring and the tube frees again. This resin/brass profile is rated 0-1.0 MPa working pressure, tolerates -750 mmHg vacuum, proofs at 1.5 MPa and works from -20 to +70 C. Do not confuse it with the metal BPC line, which trades 0.1 MPa of pressure for a 150 C ceiling. The 1/2in thread arrives with sealant pre-applied, so it seals on the port without extra tape.

Large pneumatic presses often have their 1/2in cylinder ports angled away from the service side of the machine. The double swivel lets the Dia 10 drop to the hose run from whatever direction the guard and press frame allow, without a second elbow.
Indexing tables and turntables present ports that rotate through the cycle. A PHW at the stationary manifold keeps the Dia 10 supply line entering at the angle the sweep of the table actually leaves you, instead of fighting it with straight fittings.
Injection-mould clamp circuits run thick tube in confined, poorly lit platen spaces. This black PHW1004D blends into painted machine steel, and the double joint absorbs the misalignment between clamp-cylinder ports and fixed manifold drops.
On the 1/2in PT rung of the PHW ladder, Dia 10 sits between two real neighbours: PHW804D below on Dia 8 tube and PHW1204D above on Dia 12. Stepping down to Dia 8 buys routing freedom in a tighter envelope but cuts the bore feeding your actuator; stepping up to Dia 12 lowers restriction on long or high-demand runs but needs a bigger bend radius in the hose. Note that the whole PHW family has no M5 option at all, and its 1/8in entry stops at Dia 8 - only the 3/8in and 1/2in threads reach the larger bores.
Match the thread to the port first: 1/2in PT is the big cylinder and valve manifold size, so this fitting belongs at main actuator supply points rather than pilot lines. If your tube run meets the port face-on, a plain PH universal elbow is simpler; reach for this PHW only when the approach angle genuinely has to bend in two planes. Tube OD must match exactly - a Dia 10 fitting will not seal on 3/8in or 12 mm tube.
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. The fitting joins Dia 10 mm soft nylon or polyurethane tube to a 1/2in PT male thread, and this D-suffix version has a black body. Thread sealant is applied at the factory, and M5 sizes do not exist on the PHW series.
No, and that is the point of the double universal design. Thread the 1/2in PT stud into the port hand-tight plus a modest turn - the factory sealant does the sealing - and the two swivel joints let you orient the tube exits afterwards. Set the tube angle with the joints, not by stressing the thread, and always insert the Dia 10 tube fully home until it bottoms before relying on the grip.
