About the Airtac POC Round Thread Straight Connector POC803
The POC803 is an AirTAC POC male connector, the compact-body version of the resin one-touch range, joining Dia 8 mm soft nylon or polyurethane tube to a 3/8 inch PT male thread. Push the tube into the chuck until it seats and the stainless spring gasket and NBR O-ring grip and seal it; pressing the POM release ring frees the tube again without tools.
This is the resin spec profile, not the metal BPC line: working pressure 0-1.0 MPa, proof pressure 1.5 MPa, temperature -20 to +70 C. The 3/8in threaded section carries sealant from the factory, so it seals on the PT taper straight out of the bag. The body around the chuck is PBT on a brass stud, with an aluminium-alloy guide and POM release button.

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 POC803 Is Used
Valve manifold drops on a rotary capper
Bottle-capping machines often have 3/8in outlets on the solenoid manifold feeding Dia 8 grip-cylinder lines. POC803 threads directly onto the manifold port and its short compact body keeps the drop clear of adjacent valves.
Wrist shrouds on pick-and-place robots
Inside a robot wrist shroud, depth is the constraint. The POC compact body leaves more clearance behind the gripper cylinder port than a standard PC connector while carrying the same 1.0 MPa feed.
Indexing conveyor cylinder ports
Stop-and-index conveyor cylinders sit under low guarding where a full-length connector fouls the cover. A 3/8in compact elbow-free connector at the port keeps the Dia 8 sensing and clamping lines inside the guard envelope.
Is the Airtac POC Round Thread Straight Connector POC803 the Right Part?
On the 3/8in POC ladder the tube options are Dia 8, 10 and 12, so Dia 8 is the smallest bore this thread accepts - step down in tube and you move to a 1/4in or smaller thread, not a smaller 3/8in part. Upward, POC103 and POC123 cover Dia 10 and Dia 12 on the same 3/8in stud for heavier cylinder feeds. Note the ladder break: a 1/2in POC only exists in Dia 10 and Dia 12, so if your port is 1/2in you must step the tube up too; Dia 8 tops out here.
Match the thread to the port taper and check the tube OD matches exactly - a Dia 8 fitting will not grip 5/16in or 1/4in tube. If you need to pass through a panel instead of screwing onto a port, the PMF bulkhead connector is the right shape, not this one.
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 POC803 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), usable under vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and an operating temperature range of -20 to +70 C. This SKU joins Dia 8 mm tubing to a 3/8 inch PT male thread, for soft nylon or polyurethane tube.
No. PT is a taper thread that seals on its flanks, and AirTAC ships POC threaded parts with sealant already applied to the thread, so POC803 can be screwed straight into a PT port. Only M5 sizes in this catalogue use a sealing gasket instead.
