About the Airtac PL L Connector PL803D-S
The PL803D-S is an AirTAC PL male elbow, a one-touch fitting that joins Dia 8 mm soft nylon or polyurethane tube to a 3/8in PT male thread turned through 90 degrees. Push the tube into the chuck until it seats and the stainless spring gasket and NBR O-ring lock the joint; press the release ring and the tube pulls straight back out. The black PBT body on the D suffix carries a SUS304 stainless stud, which is exactly what the -S ordering code buys on the PL family.
This is the standard resin/brass one-touch spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a service temperature of -20 to +70 C. AirTAC ships the stud with thread sealant already applied, so the elbow is ready to wind into the port without extra tape or paste.

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 PL803D-S Is Used
Rotary actuator behind a machine guard
A straight stud on a rotary actuator forces the hose to bend sharply against the guard sheet. The PL803D-S turns the run 90 degrees at the port so the Dia 8 tube leaves parallel to the mounting face, removing the kink and the chafe point in one fitting.
Valve manifold outlet on a pneumatic press
AirTAC valve manifolds commonly carry 3/8in PT outlets side by side. The elbow body drops below adjacent straight fittings, so two PL803D-S units fit the same manifold face without the Dia 8 tubes colliding.
Conveyor gate cylinder in a tight frame
Sorting-gate cylinders sit between conveyor side frames where every millimetre of stud projection counts. The compact elbow keeps the air line inside the frame rail, and the SUS304 stud resists the wash-down grit that conveyor lines see daily.
Is the Airtac PL L Connector PL803D-S the Right Part?
On the PL ladder at 3/8in thread, the neighbour below is PL603 (Dia 6 tube) and the neighbour above is PL103 (Dia 10 tube). Stepping down frees panel space and suits smaller actuators; stepping up moves more air on the same port thread because capacity tracks the tube bore, so a flow-heavy cylinder that cycles slowly on Dia 8 will respond noticeably faster on Dia 10. Across threads, the same Dia 8 tube also exists as PL802 (1/4in) and PL804 (1/2in), so match the stud to the port on the machine, not to the tube.
Tube OD must match exactly: a Dia 8 chuck will not grip 5/16in or Dia 6 tube reliably, and no adapter in this catalogue stretches a size. If the port sits where a straight connector would kink the hose against a guard or wall, the 90 degree PL body is the correct answer; if the port must pass through a panel, look at the PLM bulkhead male elbow 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 PL803D-S FAQ
It is a one-touch male elbow for Dia 8 mm tube on a 3/8in PT male thread. 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. Body PBT in black (D suffix), stud SUS304 with pre-applied sealant, POM release button, stainless spring gasket, NBR O-ring. Applicable tubing is soft nylon or polyurethane only.
No. On PL-family codes the -S means the stud is SUS304; the body stays PBT and every published figure is identical to the standard PL803D. It is not a higher-rated part and it is not a solid stainless body - that distinction belongs to the PC/POC -S connectors, where the body itself is SUS304.
