About the Airtac PL L Connector PL804-S
The PL804-S is an AirTAC PL male elbow: a 90-degree one-touch fitting that turns a Dia 8 mm soft nylon or polyurethane tube into a 1/2 in PT male thread. Push the tube in and the stainless spring gasket and chuck grip it; press the release ring to free it, so an elbow bolted hard against a machine face can still be disconnected with one finger.
The -S suffix is the stainless variant. On the PL family the body itself stays PBT - the stud that carries the 1/2 in thread is what becomes SUS304, so specify it for the corrosion exposure at the port, not as a solid stainless fitting. Ratings are unchanged from the standard resin line: 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C, and -750 mmHg vacuum. The thread ships with sealant already applied; no tape is needed.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PL L Connector PL804-S Is Used
Poultry plant wash-down actuator
On a scald-tank conveyor, the cylinder port sits under a daily caustic hose-down. The SUS304 stud resists attack at the thread seat while the elbow keeps 8 mm tubing flat against the frame instead of looping into the wash zone.
Plating line rinse-station lift
Acid rinse mist corrodes brass studs on pick-and-place cylinders. A PL804-S puts the 1/2 in PT thread into the manifold riser and swings the tube 90 degrees down the tank edge, clear of the drip path.
Marine deck hatch cylinder
Salt-laden air eats plated threads on deck-mounted hatch actuators. The stainless stud at the 1/2 in port holds up, and the elbow turns the 8 mm run down inside the coaming where crew cannot snag it.
Is the Airtac PL L Connector PL804-S the Right Part?
On the PL ladder, a 1/2 in thread is offered in Dia 6, 8, 10 and 12. The PL604 steps down to a 6 mm bore for lighter lines, while the PL1004 opens to 10 mm where a heavier cylinder needs more feed; what changes is the bore and the flow headroom, not the thread. If your panel design needs a straight run instead of a right angle, the PC series covers the same 8 mm x 1/2 in pairing in a straight body.
Match the tube exactly: this chuck is cut for Dia 8 mm and will not seal on 5/16 in imperial tube even though the numbers look close. Check the port before you order the thread - a 1/2 in elbow on a 3/8 in tapped port needs a reducing bush, and the extra stack height can foul a guard or manifold wall.
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 PL L Connector PL804-S FAQ
It is a one-touch male elbow joining Dia 8 mm tubing to a 1/2 in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), and working temperature -20 to +70 C. It runs on soft nylon or polyurethane tube. The stud is SUS304; the body is PBT with a POM release button, aluminium-alloy guide and NBR O-ring.
No, and it matters when you write a spec. On PL-series -S parts AirTAC makes the threaded stud SUS304 while the elbow body remains PBT. That combination is deliberate: the thread seat is where corrosion starts, and the PBT body keeps the release ring light and non-seizing. If you need a fully stainless straight body, the PC series in -S is the family to look at instead.
