About the Airtac POC Round Thread Straight Connector POC1003
The POC1003 is an AirTAC POC male connector, the compact-bodied one-touch fitting in the resin range. Its brass stud carries a 3/8in PT male thread for the port, and the chuck on the front accepts exactly 10 mm outside-diameter soft nylon or polyurethane tubing. Push the tube in and the stainless spring gasket plus POM chuck clamp it instantly; press the POM release ring and the tube slides free again.
This part runs on the standard resin spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The 3/8in thread arrives from AirTAC with sealant already applied, so the port seals on first assembly with no extra tape. Keep it out of the metal BP line by mistake and you get a fitting rated hotter than you need; keep it in this line and you get the wider pressure and low-temperature rating the POC family is known for.

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 POC1003 Is Used
Rotary indexing table air feed
A 10 mm drop feeding the clamp cylinder circuit of a rotary indexing table on an assembly machine, where the compact POC body clears the rotating fixture guard better than a full-size connector.
End-of-arm ejector supply
Supply leg to a vacuum ejector on a palletising robot gripper, where the short compact body keeps the 3/8in port connection clear of the tooling plate and speeds tube swaps at changeover.
Packaging machine manifold branch
A 3/8in manifold port on a flow-wrap machine feeding bag-clamp actuators, where dense port spacing makes the POC1003's reduced body diameter the difference between fittings that fit and ones that collide.
Is the Airtac POC Round Thread Straight Connector POC1003 the Right Part?
On a 3/8in stud the POC ladder offers only three bores: Dia 8 below this one, Dia 10 here, and Dia 12 above. Stepping down to POC803 buys you nothing on flow if your cylinder or valve port is fed by 10 mm tube, because the smaller chuck will choke the line at the joint; stepping up to POC1203 only makes sense if the run is already 12 mm. Note also that if you move to a 1/2in thread on this series, the choice narrows to Dia 10 or Dia 12 only. Match the thread to the drilled or tapped port you have, and the tube OD to the tube you already run - a Dia 10 chuck will not grip 3/8in imperial tube, which measures 9.5 mm and is a different product family entirely.
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 POC1003 FAQ
Tube connection: Dia 10 mm outside diameter soft nylon or polyurethane tubing. Thread: 3/8in PT male, supplied with sealant pre-applied. Working pressure: 0-1.0 MPa (0-10 kgf/cm2). Negative pressure: -750 mmHg (10 Torr). Proof pressure: 1.5 MPa. Operating temperature: -20 to +70 C. Release button and chuck are POM, the guide is aluminium alloy, the spring gasket is stainless and the O-ring is NBR; the threaded body is PBT over a brass stud.
No. The chuck grips 10 mm metric outside-diameter tube only. North American 3/8in tube measures 9.5 mm and will not seal in this fitting - the numbers are close enough to cause silent leaks, so always confirm the tube is genuinely metric 10 mm. If your run is imperial tube, use a fitting from the separate inch-sized series instead.
