About the Airtac POC Round Thread Straight Connector POC1204
The POC1204 is AirTAC's compact male connector, the shorter-bodied sibling of the PC series, terminating a Dia 12 mm soft nylon or polyurethane tube onto a 1/2 in PT male thread. The shortened body is the whole point: it clears cylinder heads, valve manifolds and guard panels where a full-length connector would foul.
Connection is the standard one-touch action: push the tube home and the internal chuck grips it for a sealed joint, then press the POM release ring to free it. This is the resin and brass spec profile, not the metal line: working pressure 0 to 1.0 MPa, negative pressure down to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The 1/2 in threaded portion ships with sealant already applied, so it seals on the PT taper without extra tape.

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 POC Round Thread Straight Connector POC1204 Is Used
Clamp cylinder on a machining fixture
A swing clamp or power clamp on a CNC fixture often sits under a chip shield where length matters. The POC1204's short body threads straight into a 1/2 in port and takes Dia 12 mm feed line without standing proud of the manifold.
Palletiser lift and gripper circuit
Large bore-and-rod cylinders on palletiser lift heads are commonly fed with Dia 12 mm tubing. A compact connector at the cylinder port keeps the fitting inside the head's swing envelope as the gripper rotates.
Bulk air drop on a packaging line
Where a 1/2 in PT drop from the main air header feeds a machine-side distribution block, the POC1204 accepts the largest Dia 12 mm run-out tube the POC series supports on this thread, minimising joints in the drop.
Is the Airtac POC Round Thread Straight Connector POC1204 the Right Part?
On the 1/2 in rung of the POC ladder the only step down is POC1004, which drops the bore to Dia 10 mm; Dia 12 is the top of this thread's range, so there is nothing larger to step up to. Stepping down to Dia 10 buys nothing if your circuit is already flowing Dia 12 - undersizing the end connection simply adds a restriction the tube upstream does not have. If you want a Dia 12 option on a longer body, the PC series carries the same 1/2 in size as PC1204.
Match the 1/2 in thread to the port you actually have: M5, 1/8 in, 1/4 in and 3/8 in POC variants all exist for smaller ports, and adapting a 1/2 in fitting down with a bushing wastes the compact profile. Remember the tube OD must match the fitting exactly - this chuck is sized for Dia 12 mm only and will not seal on 12.7 mm (1/2 in) imperial tube.
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 POC Round Thread Straight Connector POC1204 FAQ
The POC1204 is a compact one-touch male connector joining Dia 12 mm tube to a 1/2 in PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), with vacuum capability to -750 mmHg (10 Torr). Proof pressure is 1.5 MPa. Operating temperature is -20 to +70 C. Applicable tubing is soft nylon or polyurethane, and the standard body colour is grey.
No. The chuck and O-ring in the POC1204 are machined for exactly Dia 12 mm outside diameter soft nylon or polyurethane tube. A 12.7 mm (1/2 in) imperial tube will not seat in the chuck and the joint will leak or blow off under pressure. If your run uses 12.7 mm tube, you need an imperial-series fitting rather than this metric part.
