About the Airtac PC Threaded Straight Connector PC801D
The PC801D is an AirTAC PC series one-touch male connector: a straight fitting that screws into a 1/8in PT port and accepts Dia 8 mm soft nylon or polyurethane tubing. Push the tube home and the stainless spring gasket plus the POM chuck clamp it against pressure; press the release ring and the tube slides straight back out. No tools, no ferrules, no re-making the joint.
This sits in the resin and brass one-touch profile, so it is rated 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The body is brass with a POM chuck, an aluminium-alloy guide and an NBR O-ring, and the male thread arrives with sealant already applied. The D suffix on a PC part changes only the release button to black - the body stays the standard grey - which helps operators pick out the Dia 8 drop on a shared machine at a glance.

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 PC Threaded Straight Connector PC801D Is Used
Pick-and-place cylinder feeds
On small pneumatic grippers and pick-and-place modules, the 1/8in PT port is the common inlet. The PC801D takes the Dia 8 supply line straight in, and the black button is easy for a technician to find when re-routing a gripper circuit mid-shift.
Conveyor air-knife and blow-off drops
Dia 8 tube carries enough path for blow-off and air-knife nozzles on food and packaging conveyors. A straight connector at the valve manifold keeps the drop short and the release ring lets the nozzle line be swapped during changeover without draining the circuit.
Control-panel pneumatic tie-ins
Where a machine builder lands a Dia 8 line on a 1/8in bulkhead or valve manifold beside the electrical cabinet, the PC801D gives a sealed PT thread out of the box. The pre-applied thread sealant means the joint can be made on site without carrying tape or paste.
Is the Airtac PC Threaded Straight Connector PC801D the Right Part?
Dia 8 on a 1/8in thread is the middle of the PC ladder. Step down to PC601 for Dia 6 tube, the usual pick for light actuator circuits, or step up to PC101 for Dia 10 when the run feeds a bigger cylinder or a distribution rail. Bore is the only thing that changes: the pressure figures above are identical across the ladder, so choose on flow path and tubing you already run, not on pressure headroom. Whichever size you pick, tube OD must match the fitting exactly - a Dia 8 chuck will not seal on 5/16in or 1/4in tube, and there is no adapter inside a one-touch body.
Match the 1/8in thread to the port: it suits compact valve outlets, small cylinder ports and 1/8in manifold tappings. If the port is a 1/4in or larger, pick the matching PC code instead of winding the thread in with extra sealant. For a turn into a confined space, the PL male elbow in the same sizes is the right shape, not this straight body.
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 PC Threaded Straight Connector PC801D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It joins Dia 8 mm soft nylon or polyurethane tube to a 1/8in PT male thread, in the resin and brass PC one-touch series with a brass body, POM chuck and NBR seal.
On the PC series the D suffix only changes the release button to black - the body, ratings and dimensions are identical to the grey-button PC801, so the two can be mixed on one machine with no performance difference. The 1/8in PT thread arrives with sealant pre-applied, so normally you just screw it in hand-tight plus a firm turn; if you remake the joint later, re-apply a PT-rated sealant and keep sealant off the first thread so it cannot migrate into the air path.
