About the Airtac PV Series L-Type Elbow Fitting PV6D
The PV6D is an AirTAC PV union elbow, a tube-to-tube one-touch fitting that turns a Dia 6 mm airline through 90 degrees with no threaded port involved. Push each tube into its chuck until it bottoms, and the stainless spring gasket and chuck grip it for a sealed joint; press the release ring and the tube slides free. Because it is a union, both ends accept tube only, so it bridges two runs of the same size rather than adapting to a valve or cylinder port.
This SKU carries the D suffix, which on the PV family colours the body black rather than grey, a useful visual tag when you want air lines to disappear against dark machine frames or to mark one circuit apart from another. It belongs to 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 temperature window of -20 to +70 C with soft nylon or polyurethane tubing. Capacity follows the 6 mm bore, so size the circuit around that internal diameter rather than expecting large-volume flow.

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 PV Series L-Type Elbow Fitting PV6D Is Used
Corner routing on a pick-and-place gantry
Air feed to the gripper on a Cartesian robot crosses a 90 degree frame corner; a PV6D on each leg keeps the Dia 6 PU tube straight into the chucks instead of letting the tube rub the aluminium edge.
Autosampler pneumatic circuit
Laboratory autosamplers run 6 mm nylon lines between solenoid manifolds and probe actuators through cramped channels; the black PV6D body sits unobtrusively inside the enclosure and releases quickly when the tubing is serviced.
Packaging machine corner turn
On a cartoning line, the Dia 6 run from the vacuum ejector supply to the box-forming station changes direction twice; union elbows at each turn prevent the kinked-tube flow restriction that slows cylinder cycling.
Is the Airtac PV Series L-Type Elbow Fitting PV6D the Right Part?
Step down to PV4D for Dia 4 sensing and pilot lines, or up to PV8D when the actuator draw needs a 8 mm bore; each step changes the internal passage and the tubing you must order. Tube OD must match exactly - a Dia 6 chuck will not hold 1/4 inch (6.35 mm) hose, and the error only shows up as a leak at pressure. If your turn instead has to land on a threaded port, a PL male elbow is the shape to look at; PV is purely for joining tube to tube.
Polyurethane tubing bends fairly tightly, but a repeated 90 degree flex at a moving member eventually kinks or fatigues the tube wall. Fitting a PV6D at the corner converts that bend into a supported pivot: the fitting takes the angle, and the tube runs straight into each chuck. On the PV series the D suffix changes the body itself to black, unlike on PC and POC where it only affects the release button.
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 PV Series L-Type Elbow Fitting PV6D FAQ
It is an AirTAC PV union elbow joining two Dia 6 mm tubes, with no thread. 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 suits soft nylon or polyurethane tubing, and the D suffix gives a black body.
No. The chuck is cut for 6 mm OD only, and 1/4 inch tube measures about 6.35 mm, so it will neither seat nor seal properly. Use a Dia 6 tube on both ends, or move to the PV4D or PV8D if your line is 4 mm or 8 mm.
