About the Airtac PC Threaded Straight Connector PC801
The PC801 is an AirTAC PC male connector, the straight threaded fitting in the one-touch resin and brass range. It terminates a Dia 8 mm soft nylon or polyurethane tube onto a male 1/8 inch PT port, so it is the part you reach for when an 8 mm air line has to enter a valve, cylinder or manifold port directly.
To make the joint, push the tube straight into the chuck until it bottoms out; the stainless spring gasket and POM chuck grip the tube, while the NBR O-ring inside seals it. Pressing the POM release button against the guide ring frees the tube again. The body is brass with PBT on the threaded section and the male thread arrives from the factory with sealant applied, so the port simply needs a firm spanner turn and no extra tape. This is the resin and brass profile: working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa, and a service temperature of -20 to +70 C.

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 PC801 Is Used
Packaging machine cylinder feed
A direct 1/8 inch PT connection from the fitting into the rear port of an 8 mm-lined double-acting cylinder on a carton sealing head, keeping the airline run short inside the guarding.
Vacuum ejector supply on PCB handling
Feeding a small vacuum ejector on a PCB pick-and-place gantry: the PC801 carries the negative pressure side down to -750 mmHg and releases quickly when the nozzle assembly is swapped.
Workbench FRL drop to air tools
Stepping off a 1/8 inch filter-regulator-lubricator outlet on a woodworking bench straight into 8 mm polyurethane hose that reaches grinders and blow guns without extra adaptors.
Is the Airtac PC Threaded Straight Connector PC801 the Right Part?
On the 1/8 inch thread, Dia 8 sits in the middle of the PC ladder. One step down is the PC601 (Dia 6 tube), which suits lighter actuators and shorter runs where flow demand is modest; one step up is the PC1001 (Dia 10 tube), the choice when the run is long or the cylinder is hungry and you want to keep pressure drop low. Note that Dia 8 is not offered on M5 in the PC series, so if you need a smaller port with an 8 mm tube you move to a 1/8 inch thread instead. Across threads, the 8 mm tube is also available as the PC802 with a 1/4 inch PT stud for larger ports. Whatever you pick, the tube outside diameter must match the fitting exactly: a Dia 8 fitting will not grip 5/16 inch or 10 mm tube, and no clamp will make it hold.
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 PC801 FAQ
The PC801 is a one-touch male connector for Dia 8 mm tube with a 1/8 inch PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the operating temperature range is -20 to +70 C. It takes soft nylon or polyurethane tube and comes in grey as standard, with a D suffix option that changes the release button to black on this series.
No. One-touch fittings hold only the exact tube outside diameter they are machined for, so the PC801 grips Dia 8 mm tube and nothing else. If your tube is nominally 1/4 inch, order the Dia 6 fittings from the same range, or re-tube the line in true 8 mm size. Mixing close sizes is the most common cause of a fitting that blows off under pressure.
