The AirTAC Airtac POC Round Thread Straight Connector POC1003D is a genuine male connector (compact) for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The POC1003D is an AirTAC POC male connector, the compact-bodied member of the one-touch range, joining Dia 10 mm soft nylon or polyurethane tubing to a 3/8 in PT male thread. Push the tube straight into the chuck and the stainless spring gasket and gripper ring lock it against pressure; press the POM release ring and the tube slides straight back out. No tools, no ferrules, no re-tightening.
This part sits on the resin/brass spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and a -20 to +70 C service window. The body is PBT on a brass stud, and the thread arrives with sealant already applied so it seals on first assembly. The D suffix here colours the release button black - on the POC series the body itself stays standard grey, unlike on PL and other families where D changes the whole body.

A Dia 10 trunk line into a clamping manifold keeps pressure drop low across multiple swing clamps, and the compact POC body fits the crowded spacing between fixture ports.
Feeding guide cylinders and stopper slides on a cartoning line, the 3/8 in stud matches typical valve-manifold outlets while the short body clears guards.
Large-bore pressing and lifting cylinders breathe hardest; connecting them with 10 mm tubing through this connector supports their air demand without starving the stroke.
On the 3/8 in thread the POC ladder runs Dia 8, Dia 10 and Dia 12 only - AirTAC does not make a POC403 or POC603, so smaller tube on a 3/8 in port means stepping up to the PC or PL series instead. Step down to the POC803 for lighter lines and smaller end-effector ports; step up to the POC1203 when the cylinder or valve port is a 1/2 in-class flow demand fed from the same 3/8 thread. Bore, not the fitting, sets the air capacity, so a Dia 10 line carries noticeably more to a large-bore actuator than an 8 mm line on the same thread.
Match the stud to the port: 3/8 in PT suits medium cylinder ports, FRL outlets and valve manifold stations. And remember tubing is matched by outside diameter exactly - a Dia 10 chuck will not seal 1/4 in imperial tube, and forcing a mismatch is the most common cause of push-in leaks.
Quick checklist
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), usable vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. This SKU joins Dia 10 mm tubing to a 3/8 in PT male thread, with a black release button on the compact POC body. Applicable tubing is soft nylon or polyurethane.
No. The chuck and spring gasket are machined for one tube OD only - Dia 10 mm here - and pushing in any other size, with or without adapters, will not seal reliably. If your line is 8 mm, order the POC803; for 12 mm tube on the same 3/8 in thread, order the POC1203. Both are standard catalogue items on this thread size.
