About the Airtac PL L Connector PL604D-S
PL604D-S is the AirTAC PL male elbow in its stainless-stud, black-body build: a one-touch fitting that turns a Dia 6 soft nylon or polyurethane tube through a fixed 90 degrees into a 1/2 in PT male thread. Push the tube home and the stainless spring gasket plus NBR O-ring seat while the internal chuck grips the tube wall; press the POM release ring and the tube frees again for repositioning.
This belongs to the resin and brass spec line, not the 0.9 MPa metal BP family: working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa, working temperature -20 to +70 C. The -S suffix puts a SUS304 stud under the body; the body itself stays PBT, shown in black here because the D suffix switches the body colour on the PL series. The standard fitting carries a brass stud, and the stud is the part that dulls and pits first in damp or washed-down air, so the stainless stud is the point of this variant.

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 PL604D-S Is Used
Cylinder ports inside tight guards
A compact pneumatic cylinder mounted inside a sheet-metal guard leaves no room for a straight connector; the PL elbow turns the Dia 6 feed along the cylinder body and clear of the sliding door.
Wash-down conveyor drops
On a bakery or dairy conveyor that gets hosed down nightly, the SUS304 stud resists the pitting a plain brass stud develops in warm, humid, detergent-laden plant air.
Oversized manifold take-offs
A 1/2 in PT port on a solenoid valve manifold is often larger than the branch it feeds; this elbow drops a Dia 6 line off that port at 90 degrees without stacking an adapter in between.
Is the Airtac PL L Connector PL604D-S the Right Part?
AirTAC makes the PL elbow on a 1/2 in thread in Dia 6, 8, 10 and 12 only, so Dia 6 is the smallest tube you can pair with this port; the next step up is the Dia 8 PL804, which adds bore while the thread stays the same. If you need Dia 4, that size exists only down at the M5, 1/8 and 1/4 threads on the PL ladder - the PL602, for example. Match the 1/2 in PT stud to a port tapped PT 1/2; threaded parts in this family arrive with sealant on the thread, while M5 sizes seal with a gasket instead.
The tube OD must match exactly: a Dia 6 chuck will not hold 1/4 in (6.35 mm) hose or 8 mm tube. Where the line has to pass through a panel wall rather than turn at it, the PLM bulkhead male elbow is the shape to look at instead.
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 PL604D-S FAQ
It is a Dia 6 mm one-touch male elbow with a 1/2 in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. Applicable tubing is soft nylon or polyurethane.
No. The dimension tables and every pressure and temperature figure match the standard PL604D. On the PL family only the stud is SUS304 - the body stays PBT (black here), with the POM release button, aluminium-alloy guide and NBR O-ring unchanged. AirTAC publishes no corrosion class or certification for the stainless variants, so none should be assumed.
