About the Airtac PC Threaded Straight Connector PC803D
The PC803D is an AirTAC PC series one-touch male connector, the workhorse straight fitting of the resin range. It joins Dia 8 mm soft nylon or polyurethane tubing to a 3/8in PT male thread. Push the tube into the chuck and the stainless spring gasket grips it for a pressure-tight seal; press the POM release ring and the tube slides straight back out.
PC fittings carry a brass body with PBT threaded sections and an aluminium-alloy guide, and they work to the resin spec profile: 0 to 1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. Note what the D suffix means here: on the PC series it changes the release button to black only - the body and every sealing part stay identical to the grey PC803.

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 PC803D Is Used
CNC machine air feed
A straight 3/8in PT thread mates cleanly with the air-inlet port on a CNC machining centre's air preparation block, with 8 mm tube running out to the tool-change circuit.
Packaging line conveyor air knives
Dropping from a 3/8in manifold port into 8 mm tube suits short runs to blow-off nozzles on a carton-sealing conveyor, where the larger bore keeps jet pressure stable.
Commercial vehicle auxiliary circuits
Brass construction and a broad -20 to +70 C range let the PC803D serve cab-levelling or tailgate-lift circuits on trucks and trailers, with the black button hiding grime in daily use.
Is the Airtac PC Threaded Straight Connector PC803D the Right Part?
At 3/8in PT, Dia 8 sits comfortably inside a supported ladder: PC603 steps down to a 6 mm bore for lighter lines and PC1003 steps up to 10 mm where a branch feeds a bigger cylinder or longer run. Bore drives flow capacity, so a heavier-acting actuator rewards the larger diameter. Across threads at the same 8 mm bore, PC802 drops to 1/4in PT and PC804 rises to 1/2in PT - match the thread to the port on the valve manifold or component, not to habit.
Tube OD must match exactly: this fitting is bored for 8 mm tube, so it will not seal on 1/4in (6.35 mm) or 5/16in (7.94 mm) imperial tube. If the port faces a wall or tight guard instead of open air, an PL male elbow or PH universal elbow turns the connection without stressing 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 PC Threaded Straight Connector PC803D FAQ
It is a PC series one-touch male connector for Dia 8 mm tubing on a 3/8in PT male thread. Working pressure is 0 to 1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg, proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tube only.
No. AirTAC ships every threaded PC fitting with sealant already applied to the PT thread, so it is ready to wind into the port by hand plus a modest turn to seat. Take care not to over-tighten, and remember the D in this code only makes the release button black - the sealant, body and sealing parts are the same as the grey PC803.
