About the Airtac POC Round Thread Straight Connector POC802
The POC802 is AirTAC's compact one-touch male connector in the mid-size bracket of the range: it joins a Dia 8 mm soft nylon or polyurethane tube to a 1/4 inch PT male thread. POC is the shorter-bodied sibling of the PC male connector - it offers the same tube and thread ladders but a reduced overall length, which is why it is usually the choice when straight connector depth is the constraint.
Installation is a one-hand job: push the 8 mm tube square into the chuck until it seats, and the stainless spring gasket and POM chuck grip it for a sealed line under the resin-line rating of 0-1.0 MPa working pressure (proof 1.5 MPa, vacuum to -750 mmHg, -20 to +70 C). Press the POM release ring and the tube slides straight back out. The body is PBT on a brass stud, the 1/4 inch thread arrives pre-coated with sealant, and the grey body can be ordered with a black release button by adding the D suffix (POC802D) - on POC the suffix changes the button only.

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 POC802 Is Used
Rotary actuator supply off a manifold
The compact POC body screws into a 1/4 inch PT manifold port feeding an 8 mm polyurethane line to a rotary actuator or gripper, where a full-length PC body would stand proud of adjacent ports.
Electronics fixture air lines
On semiconductor and PCB handling fixtures, 8 mm nylon runs from valve manifolds to small vacuum ejectors and air cylinders use the POC802 where copper-free choice is not required but fast tube changes during fixture changeover are.
Packaging machine drop ladder
On cartoning and wrapping machines, a bank of valve outlets at 1/4 inch PT steps out to 8 mm tube feeding bag-clamp cylinders; POC's short body keeps clearance between closely pitched solenoid valve outlets.
Is the Airtac POC Round Thread Straight Connector POC802 the Right Part?
On the POC 1/4 inch thread ladder this size sits between POC602 (Dia 6) below and POC1002 (Dia 10) above. Stepping down to 6 mm gives you a slimmer tube for tight routing at the cost of bore; stepping up to 10 mm suits actuators that want more volume per stroke. The full 1/4 inch POC ladder runs 4, 6, 8, 10 and 12 mm, so 8 mm is the natural centre of the range. If your port is only 1/8 inch, note that the POC 1/8 inch ladder tops out at Dia 10 - a POC801 does not exist, so you would need to drop to 6 mm or stay on the 1/4 inch port.
Tube OD must match the fitting exactly: a Dia 8 chuck will not seal or hold 1/4 inch (6.35 mm) imperial tube, even though the thread below it is a 1/4 inch PT. Measure the tube, not the thread, before ordering.
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 POC802 FAQ
It is a Dia 8 mm one-touch male connector with a 1/4 inch PT thread on the resin (non-metal) POC profile. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Tubing is soft nylon or polyurethane, and the grey body is PBT on a brass stud with a POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
No. AirTAC supplies threaded one-touch parts with sealant already applied to the male thread, so the 1/4 inch PT stud is ready to screw into the port as received. (Only M5 sizes in this catalogue use a sealing gasket instead.) Re-tightening after disassembly may call for a little fresh sealant, but there is no published torque value - snug to seal, do not over-wrench the PBT body.
