About the Airtac PV Series L-Type Elbow Fitting PV12D
The PV12D is an AirTAC PV series one-touch union elbow: a tube-to-tube fitting that joins two Dia 12 mm soft nylon or polyurethane tubes at a 90 degree angle without using a threaded port anywhere. Push each tube into the chuck until it bottoms out and the stainless spring gasket and NBR O-ring seal it; press the POM release ring toward the body and the tube pulls free. Because it is a union, both legs are tube ends, so you can turn a corner mid-run even where no port or manifold face is available.
This is the resin one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The D suffix on PV parts changes the whole body to black rather than just the release button, which on PC or POC is all it would alter - handy when the fitting sits on a visible machine frame and the standard grey would stand out.

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 PV12D Is Used
Pneumatic press frame corner routing
On a small pneumatic press or clamping station built from Dia 12 main lines, the PV12D turns the run at the frame corner in-line, so the feed can follow the structure without needing a valve or manifold port at every bend.
Vacuum pick-and-place on a carton collator
Carton collators and sheet feeders hold parts with ejector vacuum at roughly -500 mmHg or deeper. The PV12D is rated to -750 mmHg (10 Torr), so it stays sealed on the suction leg between the cups and the vacuum generator even at 90 degree turns on the gantry.
Enclosed guarding behind a weld cell panel
Where a pneumatic run passes behind fixed guarding in a weld cell, hands cannot reach to service a straight push-in joint. A union elbow placed at the guard edge lets the tube turn through 90 degrees and still be released by pressing the ring through the access slot.
Is the Airtac PV Series L-Type Elbow Fitting PV12D the Right Part?
Dia 12 is the top of the PV size ladder - AirTAC lists no Dia 16 union in this catalogue - so the only real neighbour is PV10 below it. Stepping down to PV10 suits lighter lines running smaller actuators; PV12 is what you pick when the whole downstream leg is Dia 12 tube and you do not want a diameter step constricting the run. If the elbow actually has to pass through a panel or sheetmetal wall, the right shape is a bulkhead union (PM) or bulkhead male elbow (PLM) with its own locknut, not this surface-run elbow.
Tube OD must match exactly. The chuck in PV12D grips 12 mm OD only; a 1/2 inch tube at 12.7 mm will neither seat nor seal. And do not add a threaded adaptor spec to this code - PV carries no thread by design, that is what the PL or PH family is for.
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 PV12D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability -750 mmHg (10 Torr), operating temperature -20 to +70 C. It joins two Dia 12 mm tubes of soft nylon or polyurethane at 90 degrees, with no thread. The D suffix means the body is black. Internals: POM release ring and chuck, aluminium alloy guide, stainless spring gasket, NBR O-ring.
No. The one-touch chuck is sized for exactly 12 mm OD tube; a 1/2 inch tube at 12.7 mm will not seat on the spring gasket and will leak or blow off. If your line is a step down, use a Dia 10 union or a PG different-diameter straight instead, and if you need 12 mm tube through a panel wall, choose the PM bulkhead union, which adds a locknut thread (M22x1 at Dia 12) for mounting.
