About the Airtac PC Threaded Straight Connector PC804
The PC804 is an AirTAC PC series male connector, the straight threaded one-touch fitting in the resin/brass range. It joins Dia 8 mm soft nylon or polyurethane tubing to a 1/2in PT male thread, so it screws straight into a large port block, valve or cylinder head. The body on the PC series is brass with a POM release button and chuck, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring - a step up in robustness over the PBT bodies used on most other threaded series in this catalogue.
Connection is genuinely tool-free: push the 8 mm tube into the chuck until it bottoms, and the grip ring plus spring gasket hold it against the standard resin-line working pressure of 0-1.0 MPa (0-10 kgf/cm2). To release, press the POM button ring towards the body and the tube slides free. Vacuum rating is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the fitting works from -20 to +70 C. The 1/2in thread arrives with sealant already applied; no extra tape is needed for a first-time assembly.

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 PC804 Is Used
Palletiser gripper cylinders
Large clamp and gripper cylinders on robotic palletising cells commonly carry 1/2in ports; the PC804 lets an 8 mm hose drop straight onto that port inside the guarded area without a reducer block.
Canning line valve islands
Filling and seaming machines with 1/2in manifold ports feed short 8 mm drops to local actuators; a straight connector keeps the cabinet wiring and tubing tidy on each station.
Conveyor transfer stoppers
Heavy transfer-conveyor stopper and lift actuators near drive gearboxes have room for a straight entry, so a rigid brass-body connector resists knocks better than an angled part in the same spot.
Is the Airtac PC Threaded Straight Connector PC804 the Right Part?
On the PC 1/2in row the ladder runs Dia 6, 8, 10, 12. Stepping down to PC604 gives a smaller bore that chokes flow on longer 1/2in-port runs, while PC1004 increases capacity if your cylinder consumes more air at stroke end - pick by the tube you are actually running, not by the port size alone. If the port is only 3/8in, PC803 carries the same Dia 8 tube on a 3/8in thread instead.
This is the right shape when the tube can approach the port head-on in a straight line. Where the fitting must pass through a panel or enclosure wall, the PM bulkhead connector with its M16x1 locknut is the better answer; where space behind the port is tight, a PL male elbow or PH universal elbow turns the run 90 degrees without kinking the tube. Whatever you choose, the tube OD must match exactly - a Dia 8 chuck will not seal on 5/16in or any other near-miss tubing.
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 PC804 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The fitting joins Dia 8 mm soft nylon or polyurethane tube to a 1/2in PT male thread and is part of the resin/brass one-touch line with a brass body and POM release button.
No first application is needed - AirTAC ships threaded one-touch parts with sealant already on the thread, so the PC804 screws into the port as delivered. Keep the tube entry square to the port when tightening so the chuck stays aligned, and remember to depress the release ring before pulling the tube out for service.
