About the Airtac PV Series L-Type Elbow Fitting PV12
The PV12 is an AirTAC PV series union elbow, a tube-to-tube fitting with no external thread at all. It joins two lengths of Dia 12 mm soft nylon or polyurethane tubing at a right angle in a single push-in operation. Push each tube home and the internal chuck grips the OD; press the release ring and the tube slides free again.
This is the resin one-touch profile, not the metal BPC line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, temperature -20 to +70 C. At Dia 12 it sits at the top of the PV ladder, so the elbow carries the largest bore the series offers. The body is grey as standard; adding D to the code changes it to black. The 90 degree body also does a job a straight run cannot: it turns the airflow without you bending stiff 12 mm PU tube around a corner, which is where kinks and flow restriction usually start.

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 PV12 Is Used
Corner turn on a press-frame run
On a pneumatic press frame, a Dia 12 main run has to turn 90 degrees at the column. Bending thick-walled PU tube that sharply kinks it and chokes flow; the PV12 elbow makes the turn while keeping the full 12 mm bore open.
Feeding a conveyor gate cylinder
Large gating cylinders on pallet conveyor lines draw real air volume. A PV12 union elbow at the top of the gate post drops the supply line down into the cylinder fitting without adding a threaded joint to leak-check.
Suction leg on a pick-and-place head
Vacuum ejector lines on electronics pick-and-place heads run at negative pressure; this elbow is rated to -750 mmHg (10 Torr), so it holds suction on the Dia 12 drop from the ejector to the cup manifold without collapsing.
Is the Airtac PV Series L-Type Elbow Fitting PV12 the Right Part?
PV12 is the largest union elbow in the PV range, and nothing bigger exists in this catalogue - there is no Dia 16 tube size. The only neighbouring size is PV10 one step down, which drops the bore to 10 mm; the gain at 12 mm is a shorter pressure drop on long runs feeding large-bore actuators. Do not try to stretch a match: the tube OD must equal the fitting size exactly, so a Dia 12 chuck will not reliably hold 12.7 mm (1/2 inch) hose.
If you need to change size mid-run, this fitting will not do it - both ends are Dia 12. Step down with a PG different-diameter straight or a PKG reducer triple branch instead. And remember the resin line tops out at 70 C; if the ambient near a hot press or dryer exceeds that, the metal BPC family (0.9 MPa, up to 150 C) is the alternative, though the tube itself is usually the first thing to fail at temperature.
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 PV12 FAQ
PV12 is a Dia 12 mm to Dia 12 mm union elbow with no thread - both ends are push-in tube ports. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and the temperature range is -20 to +70 C. It is the resin one-touch profile and takes soft nylon or polyurethane tubing.
No. The PV12 grips Dia 12 tubing on both ends; the chuck will not seal a smaller OD. For a size change use a PG different-diameter straight union (for example PG12-10) or a PKG reducer triple branch union if you also need to split the flow. Keep the tube OD matched to each port exactly - a near-miss size such as 1/2 inch hose in a Dia 12 port will weep or blow off under pressure.
