About the Airtac PV Series L-Type Elbow Fitting PV8
The PV8 is an AirTAC PV union elbow, a tube-to-tube one-touch fitting with no external thread at all. Both legs accept Dia 8 mm soft nylon or polyurethane tubing, and the body turns the air path through 90 degrees, so a right-hand turn costs no threaded adapter and no extra male stud.
Push each tube straight into its chuck and the stainless spring gasket plus the POM chuck grip it on the spot; press the release ring to free it again. This is the resin/brass one-touch profile: 0 to 1.0 MPa working pressure (10 kgf/cm2), -750 mmHg vacuum capability, 1.5 MPa proof pressure and a -20 to +70 C service window. The standard body colour is grey, and because there is no thread, the part arrives ready to use with no sealant step.

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 PV8 Is Used
Packaging machine gripper arm
Takes the 8 mm feed line around the corner of a small pneumatic gripper on a form-fill-seal machine, keeping the hose run inside the arm profile without a threaded stud protruding.
Robot dress pack corner
A 90 degree turn on the air line inside a six-axis robot's dress pack, letting the tubing flex around the elbow instead of kinking at a sharp bend.
Control cabinet routing
Turns the 8 mm branch from a valve manifold toward a cylinder port along the cabinet wall, holding the run flat against the panel instead of looping it into other cables.
Is the Airtac PV Series L-Type Elbow Fitting PV8 the Right Part?
Step down to PV6 for a 6 mm union elbow on light-duty actuators, or up to PV10 when the branch feeds a larger-bore cylinder; the 8 mm bore here is the middle of the PV ladder and holds a useful flow margin at moderate line lengths. If the turn must land on a threaded port instead of another tube, a PL male elbow is the shape to reach for - the PV only ever mates tube to tube.
Tube OD must match exactly on both legs: an 8 mm chuck will not seal 1/4 in or 5/16 in hose, and no adapter changes that. Check the minimum straight length of tubing entering each chuck too - an elbow needs enough insert depth to hold under pull-out loads.
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 PV8 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It is a tube-to-tube union elbow for Dia 8 mm soft nylon or polyurethane tubing on both legs, with no thread, in the standard grey resin body.
Push each tube fully home until it bottoms in the chuck - the stainless spring gasket and POM chuck only grip and seal over the full insertion depth, so a shallow insert is the most common cause of a weeping union elbow. AirTAC publishes no reuse cycle count for these joints; every re-assembly should be made on a clean, square-cut tube end for a reliable seal.
