About the Airtac POC Round Thread Straight Connector POC1203D
The POC1203D is an AirTAC POC compact one-touch male connector: the shorter-bodied version of the PC series, made to end a 12 mm soft nylon or polyurethane tube on a 3/8 inch PT male thread. Assembly is a single push - the tube slides past the POM chuck, which grips the OD and the stainless spring gasket seals it; pressing the release ring lets the tube back out for rework. The trailing D makes this the black release-button variant, and on the POC series that is exactly what it changes: the body stays standard grey, only the button colour differs.
This is the resin/brass spec 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, and a service temperature of -20 to +70 C. The 3/8 inch thread arrives with sealant already applied, so it seals into the port on the first pass without extra tape or compound.

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 POC1203D Is Used
Valve manifold outlets on palletizers
The shortened POC body sits where a full-length PC connector would foul adjacent solenoid valves on a packed palletizer manifold, handing 12 mm lines to gripper and clamp cylinders.
Ring-mains dropping from an air-prep combo unit
A 3/8 inch PT port on an FRL or distribution block steps cleanly onto 12 mm trunk tubing, and the push-fit joint lets a technician re-route the drop in seconds without a spanner on the tube side.
Rotary indexing tables under tight guards
Compact connectors at the table's fixed ports keep the whole pneumatic stack inside the guarding envelope, feeding 12 mm supply lines to the rotary actuator and tool clamps.
Is the Airtac POC Round Thread Straight Connector POC1203D the Right Part?
On the POC 3/8 inch row, Dia 12 is the top of the ladder: the next size down is POC1003 (Dia 10), which suits lighter actuator lines and gives a slightly shorter overall stack; there is no Dia 16 step above, so POC1203D is the largest-tube 3/8 inch compact connector in the range. If your port is 1/4 inch instead, POC1202 carries the same 12 mm tube on the smaller thread. Match the thread to the actual port - 3/8 inch PT here, and do not adapt it down with extra reducers if a direct SKU exists.
The tube must be exactly 12 mm OD. SAE 1/2 inch hose at 12.7 mm will not seat in the chuck and will leak or blow off; tube OD tolerance is the one dimension that cannot be negotiated.
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 POC1203D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), usable under vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It connects Dia 12 mm soft nylon or polyurethane tube to a 3/8 inch PT male thread, and the D suffix denotes the black release button.
No. A POC1203D holds tube that measures exactly 12 mm outside diameter; nominal 1/2 inch hose is 12.7 mm and will neither seat in the chuck nor seal. Use soft nylon or polyurethane tube in the correct OD, cut square, and push it fully home to the stop.
