About the Airtac PL L Connector PL804D-S
The PL804D-S is an AirTAC PL male elbow from the resin one-touch family, joining Dia 8 mm soft nylon or polyurethane tube to a 1/2 in PT male thread at a fixed 90 degrees. The elbow turn lets the tube run vertically off a horizontal port, so a hose dropped into a crowded machine frame does not fight the fitting for space. The -S suffix means the male stud is SUS304 stainless steel; the elbow body remains PBT, finished black because the D suffix on this series changes the whole body colour, not just the release button.
Connection is one-touch: push the Dia 8 tube straight home and the internal chuck grips it against the stainless spring gasket and NBR O-ring seal; press the POM release ring to free it. This is the resin spec profile, rated 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C. The 1/2 in thread arrives with sealant already applied, so it seals on the PT taper without extra tape.

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 PL804D-S Is Used
Clamp cylinder on a frame press
Plumbed into the 1/2 in port of a large bore clamping cylinder on a timber-frame or steel-fabrication press, the elbow points the 8 mm supply line down along the machine column instead of across the operator's path.
Directional valve exhaust and supply lines
Where a 1/2 in PT valve manifold sits close to a machine wall, the 90 degree turn lets Dia 8 tubing drop vertically, and the stainless stud stands up to splashes on a dairy or bottling conveyor gate valve station.
Wet-area actuator take-offs
On packaging machinery that is hosed down between runs, the SUS304 stud and black PBT body resist corrosion at the port interface, while the one-touch release ring lets maintenance swap 8 mm lines without tools.
Is the Airtac PL L Connector PL804D-S the Right Part?
On the 1/2 in thread the PL ladder runs Dia 6, 8, 10 and 12 mm, so Dia 6 (PL604D-S) is the step down and Dia 10 (PL1004D-S) the step up; stepping changes the bore the air sees and the tubing you must stock, since the chuck holds one OD only - a Dia 8 fitting will not grip 5/16 in or 10 mm tube. On the thread side, 1/2 in is the largest port this series offers, so the only step down is 3/8 in (PL803D-S); match it to the actual port, because forcing a 1/2 in stud into a 3/8 in tapped hole is a common strip-out.
Pick this elbow shape when the port faces a guard or wall and a straight connector would kink the hose. If you need to pass through a panel instead, the PMF bulkhead female connector is the right family - note that its locknut for Dia 8 tube is M16x1.
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 PL804D-S FAQ
It is a one-touch male elbow taking Dia 8 mm soft nylon or polyurethane tube into a 1/2 in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds -750 mmHg (10 Torr) vacuum, proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. The SUS304 stud does not change any of these figures from the standard PL804D.
No. On the PL elbow family the -S suffix upgrades the male stud to SUS304; the elbow body is PBT (black here, as the D suffix colours the body on this series). Only the PC and POC straight connectors receive a full SUS304 body in the stainless line. The fitting uses a PT taper thread and arrives with sealant applied, so no extra thread tape is needed.
