About the Airtac PV Series L-Type Elbow Fitting PV8D
The PV8D is an AirTAC PV series one-touch union elbow, a tube-to-tube fitting that joins two runs of Dia 8 mm soft nylon or polyurethane tubing at a right angle. It carries no thread at all: both ends are the same push-in socket. Press the tube home and the internal stainless spring gasket and chuck grip the OD; press the release ring and the tube frees again.
This is the standard resin spec profile, rated 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The D suffix makes the PBT body black rather than the standard grey, which matters on machines where grey fittings stand out against dark enclosures or panels. Inside, the chuck is POM, the guide is aluminium alloy and the O-ring is NBR, matching the rest of the resin one-touch range.

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 PV8D Is Used
Robot dress pack routing
Turning an 8 mm supply line through 90 degrees inside a robot arm's cable dress pack, where a rigid right-angle bend in the tube would kink or fatigue over millions of cycles.
Packaging machine dark frames
Routing air behind the black guarding of a form-fill-seal or cartoning machine, where the black PV8D body blends in instead of showing grey fittings through the windows.
CNC spindle-area plumbing
Joining two 8 mm nylon runs around a corner inside a machining centre's coolant-shielded enclosure, keeping the line clear of the spindle and chip path without extra brackets.
Is the Airtac PV Series L-Type Elbow Fitting PV8D the Right Part?
PV8D sits in the middle of the PV union elbow ladder. Step down to PV6 for lighter 6 mm runs feeding compact actuators or signal-air circuits, or step up to PV10 when a 10 mm line supplies a larger cylinder and needs the extra bore. The elbow shape itself does not change; only the tube bore and the flow headroom do. Note that PV has no mini variant - the -M suffix exists only on PC and PL.
Because both ends are sockets, tube OD must match exactly on each side: an 8 mm fitting will not hold 1/4 inch or 6 mm tube. If one leg of the turn needs a threaded port instead, use a PL male elbow; if the turn is in a panel wall, PM or PLM is the better shape.
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 PV8D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability down to -750 mmHg (10 Torr), operating temperature -20 to +70 C. Both ends accept Dia 8 mm soft nylon or polyurethane tube, and there is no threaded port - it is a pure tube-to-tube union elbow.
No. A PV union accepts one tube OD only, and the PV8D grips 8 mm tube on both sides. To change diameter in line, use the PG different-diameter straight union (for example PG8-6), or fit a PGJ plug-in reducer. Mixing sizes on a PV fitting will not seal.
