About the Airtac POC Round Thread Straight Connector POC1203
The POC1203 is AirTAC's compact male connector from the POC one-touch family: a Dia 12 mm push-in port on one side and a 3/8 inch PT male thread on the other. POC is the short-bodied version of the PC connector, so it reaches into ports where a standard straight body would foul adjacent hardware.
It belongs to the resin and brass spec profile, not the metal BPC line: working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa, and a service temperature of -20 to +70 C. To make the joint, cut the soft nylon or PU tube square, push it into the chuck until it seats, and the stainless spring gasket and NBR O-ring seal it; press the POM release ring to free the tube again. The 3/8in thread arrives with sealant already applied, so it goes onto the port as delivered.

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 POC1203 Is Used
Injection moulding machine take-off
A 12 mm main air drop from the mould-header regulator lands on a 3/8in port; the short POC body fits where deep mould faces leave little thread engagement room.
Bottling line conveyor actuator supply
Large pneumatic pushers and gate cylinders on filling lines are commonly plumbed in Dia 12 tubing; this connector ties the run to a 3/8in valve-manifold outlet.
Truck-mounted tail-lift compressor line
Vehicle body builders run 12 mm nylon from the onboard compressor; the compact straight connector suits chassis brackets where a full-length body would protrude.
Is the Airtac POC Round Thread Straight Connector POC1203 the Right Part?
At 3/8in thread this is the top tube size: Dia 12 mm is the largest POC offers here, with Dia 10 (POC1003) and Dia 8 (POC803) stepping down. Dropping to Dia 10 reduces the bore your air path sees, worth considering only if the circuit feeds smaller actuators. If the thread is too coarse for the port, POC1204 keeps the 12 mm tube on a 1/2in PT stud instead.
Match the thread to the port size on the manifold or valve, and check the compact body clears neighbouring fittings. Tube OD must match exactly - a Dia 12 socket will not grip 1/2 inch (12.7 mm) hose or a Dia 10 tube, and there is no safe way to shim it.
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 POC1203 FAQ
This is a Dia 12 mm tube, 3/8 inch PT male thread compact one-touch connector from the resin/brass range. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. Tubing is soft nylon or polyurethane, the thread ships with sealant applied, and grey is standard (order the D suffix for a black release button).
No. The chuck is machined for exactly 12 mm OD soft nylon or PU tubing; 1/2 inch nominal hose (12.7 mm) and Dia 10 or Dia 8 tube will not seal or retain. Braided or reinforced hose is also outside the design - the collet grips soft round tube only, and hard-wall hose can damage the gasket.
