About the Airtac PH-1 Hex Head Toggle Joint PH804D
The PH804D is an AirTAC PH series universal male elbow, a one-touch fitting that joins Dia 8 mm soft nylon or polyurethane tubing to a 1/4 in PT male thread. What makes the PH shape different from a fixed PL elbow is the universal joint: the threaded stud turns in the body, so the tube entry direction can be set at any angle after the thread is installed, then the fitting is swung into position. Push the tube in and the stainless spring gasket chuck grips it; press the release ring and it frees.
This is the resin and brass one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. The D suffix makes this version black - and on the PH series that means the whole body, not just the release button as it would on a PC or POC straight connector. The 1/4 in thread arrives with sealant already applied; M5 sizes in this catalogue use a sealing gasket instead, but 1/4 in does not.

Fitting & Sealing Notes
- check Cut the tube square and clean before pushing it home, or the seal will leak.
- check Push until it stops, then pull back to check the chuck has gripped.
- check To release, press the collet ring fully in and pull the tube out.
- check Threaded parts arrive with sealant on the thread; M5 sizes use a sealing gasket.
- check Match the tube OD exactly - a 6 mm fitting will not hold 1/4" tube.
Where the Airtac PH-1 Hex Head Toggle Joint PH804D Is Used
Rotary indexing table actuation
The swivelling stud on a PH804D lets the Dia 8 feed line follow a clamping cylinder that rocks through part of a turn, where a fixed PL elbow would bind the tube against the guard sheet.
Fixture clamping on a welding jig
Jig builder can install the 1/4 in PT thread into the clamp block first, then angle the Dia 8 tube entry clear of weld guns and clamp arms during final plumbing.
Valve manifold test ports
A black PH804D screwed into a spare manifold port gives a Dia 8 test take-off pointing whichever way the gauge hose needs, with the one-touch release for fast hook-up.
Is the Airtac PH-1 Hex Head Toggle Joint PH804D the Right Part?
On the 1/4 in rung of the PH ladder, the neighbours are Dia 6 below (PH802) and Dia 10 above (PH1002) - note the PH series stops at Dia 10 for 1/4 in, so if your next size up is 12 mm you have to step the thread to 3/8 in or 1/2 in as well. Stepping 6 to 8 mm roughly increases the bore your air travels through; stepping 8 to 10 mm suits longer runs or higher-consumption actuators. Whatever you choose, the tube OD must match the fitting exactly - a Dia 8 chuck will not seal on 5/16 in or 10 mm tube.
Pick a PH over a PL when you cannot predict the final tube direction at install time, or when the port sits at an awkward angle that a fixed 90 degree elbow would fight. If you need to pass through a panel wall rather than angle off it, the bulkhead shapes PM or PLM are the correct alternative.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
Airtac PH-1 Hex Head Toggle Joint PH804D FAQ
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. It takes Dia 8 mm soft nylon or polyurethane tube on a 1/4 in PT male thread. The one-touch chuck is a stainless spring gasket with an NBR O-ring seal; the D suffix gives a black body.
A PL male elbow leaves the tube at a fixed 90 degrees from the thread. The PH804D's threaded stud rotates within the body, so after the 1/4 in thread is torqued into the port you can set the tube direction at any angle and lock the entry point there. Use this when the port orientation and the tube routing cannot be planned to meet at exactly 90 degrees.
