About the Airtac POC Round Thread Straight Connector POC1003-S
The POC1003-S is AirTAC's compact male connector in the SUS304 stainless option. It joins Dia 10 mm soft nylon or polyurethane tubing to a 3/8in PT male thread, and it does so with a body that is noticeably shorter than the standard PC connector - useful wherever the port sits close to a wall, a guard or a neighbouring fitting. Push the tube in and the internal chuck grips it; press the release ring and it frees again.
On the POC straight connectors the -S suffix changes the body itself to Stainless steel 304 and the whole part is copper-free - unlike the elbows and tees in the range, where the visible body stays PBT and only the stud is stainless. The release button and chuck remain POM, the guide is aluminium alloy, the spring gasket is stainless and the O-ring is NBR. Ratings are unchanged from the resin line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C. The 3/8in thread arrives with sealant already applied.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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-S Is Used
Wash-down areas on food conveying lines
A compact stainless connector at the 3/8in port of a conveyor-mounted air cylinder survives hose-down and cleaning chemicals that would pit a brass body.
Copper-free air feeds in electronics plants
Dia 10 supply drops to soldering and clean-process stations avoid copper particles entering sensitive production air.
Marine and dockside actuation
Hatch, ramp and winch cylinders on vessels take 10 mm lines via a corrosion-resistant connector at the 3/8in port.
Is the Airtac POC Round Thread Straight Connector POC1003-S the Right Part?
Within the POC 3/8in ladder, this SKU sits between POC803 (Dia 8 tube) below and POC1203 (Dia 12 tube) above. Stepping down to 8 mm frees panel space and lowers air demand per circuit; stepping up to 12 mm moves more volume through the same compact footprint. The tube OD must match exactly - a Dia 10 chuck will not reliably hold 12 mm or a nominal 3/8in hose.
Choose the compact POC over the standard PC when the 3/8in port is recessed or flanked by other fittings and a full-length connector simply will not fit. If the line needs to turn, an elbow such as PLF or PHF in the same stainless option is the correct next step rather than bending the tube.
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-S FAQ
Compact male connector, Dia 10 mm tube x 3/8in PT male thread, SUS304 copper-free body. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. Applicable tubing is soft nylon or polyurethane; the grey release button and chuck are POM with an NBR O-ring.
No. The 3/8in in the code refers to the PT thread size. The tube side grips exactly Dia 10 mm outside-diameter soft nylon or polyurethane tube. A 12 mm tube, or an imperial hose, will not seal in a Dia 10 chuck - order the matching OD to keep the joint leak-free.
