About the Airtac POC Round Thread Straight Connector POC1204D
The POC1204D is an AirTAC POC male connector, the compact version of the one-touch threaded fitting range. It accepts Dia 12 mm soft nylon or polyurethane tubing on the tube side and carries a 1/2in PT male thread for the port side. Push the tube straight in and the stainless spring gasket and chuck set grip it against the NBR O-ring seal; press the release ring and the tube slides back out, so circuit changes take seconds instead of a spanner session. On the POC series the D suffix changes the release button only to black - the PBT body stays grey, which matters if you are matching existing hardware on a machine.
This is the resin/brass one-touch profile, not the metal BPC line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr), and a temperature window of -20 to +70 C. The POC body is shorter than a standard PC of the same size, so it buys clearance where a long male stud would foul a guard or a manifold wall. Dia 12 with a 1/2in thread is the top rung of the POC ladder - it feeds the biggest flows this series offers.

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 POC1204D Is Used
Injection moulding machine actuation
Large clamp and ejector cylinders on moulding machines commonly run 12 mm lines from 1/2in valve ports. The compact POC body clears the tie-bar side of the platen where a full-length male stud would not.
Packaging line main air drop
Case packers and carton sealers use 12 mm trunks from the FRL into valve manifolds. A 1/2in male connector at the manifold inlet keeps the drop push-fit end to end, so a seized station can be re-plumbed during a changeover.
Pneumatic press valve outlet
Directional control valves on medium pneumatic presses are frequently 1/2in ported. The POC1204D turns that port into a push-fit station for a 12 mm line feeding the press cylinder, with the black button easy to find on a dark valve block.
Is the Airtac POC Round Thread Straight Connector POC1204D the Right Part?
Sizing both ways: one step down on tube is POC1004, Dia 10 tube on the same 1/2in PT thread, for lighter circuits where a 10 mm line is already generous. There is no larger POC tube size - Dia 12 is the end of the range, so if you need Dia 16 flow you are outside this catalogue entirely. On the thread side, POC1203 steps the port down to 3/8in while keeping the same 12 mm bore, useful when the 1/2in port is really feeding a 3/8in leg. One caution: match the tube OD exactly. A Dia 12 chuck will not seal reliably on a nominal 1/2in (12.7 mm) hose, and it will not hold imperial tube at all. The 1/2in thread arrives with pre-applied sealant, so no extra tape is needed on installation.
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 POC1204D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure to -750 mmHg (10 Torr), operating temperature -20 to +70 C. Tube side takes Dia 12 mm soft nylon or polyurethane tubing; thread side is a 1/2in PT male port supplied with sealant. It is the compact POC body in the resin/brass profile, with a black release button.
No. The POC1204D is rated to +70 C at the fitting, and AirTAC specifies soft nylon or polyurethane tube for this resin line. If your circuit runs hotter, you need the metal BPC family, which is rated to +150 C - and even then the tube itself, not the fitting, usually becomes the limiting factor at high temperature.
