About the Airtac PL L Connector PL803D
The PL803D is an AirTAC PL series male elbow, a one-touch fitting that joins Dia 8 mm soft nylon or polyurethane tubing to a 3/8 in PT male thread at a fixed 90 degrees. Push the tube into the chuck and the stainless spring gasket grips it for pressure-tight service; press the POM release ring and the tube frees off for rework. The body is PBT with a brass stud, and the thread ships with sealant already applied so it goes straight onto the port.
The D suffix makes this the black-bodied version of the PL803, which matters on machines where grey fittings stand out against dark guards, enclosures or anodised manifolds. As a resin-line part it is rated 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C - figures that stay identical across the whole colour range.

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 Is Used
Pneumatic press cylinder drop
Elbow directly into the rear port of a compact air press so the Dia 8 supply line runs vertically along the frame instead of fouling the ram stroke.
Packaging machine guard run
The black PBT body disappears against dark machine guards and extruded frames on wrapping and cartoning lines where grey fittings are visually distracting.
Rotary indexer air feed
A 90 degree turn off a rotary indexing table keeps the Dia 8 hose clear of the rotating face while the 3/8 in PT stud seats into the index table port.
Is the Airtac PL L Connector PL803D the Right Part?
On the PL ladder at 3/8 in thread you can step down to PL603 (Dia 6) for lighter lines or up to PL1003 (Dia 10) for higher delivery to a cylinder; Dia 12 also exists on this thread. Stepping the bore changes the air speed and capacity the fitting can carry, so match it to the tube actually run - an elbow bored for Dia 8 will not grip 1/4 in (6.35 mm) hose even though the numbers look close.
Choose PL over PC only when the run must turn 90 degrees at the port; for a straight drop use a PC male connector, and where the port face is cramped an extended PLL gives wrench clearance. Verify the 3/8 in thread against the cylinder or valve port before ordering - oversizing the thread to chase capacity is a common mistake.
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 FAQ
This black male elbow takes Dia 8 mm tubing into a 3/8 in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it handles vacuum to -750 mmHg, proof pressure is 1.5 MPa, and the operating temperature range is -20 to +70 C. Tubing must be soft nylon or polyurethane.
No. AirTAC applies thread sealant to the 3/8 in PT stud before dispatch, so the fitting screws straight into the port. Hand-tighten then snug with a wrench on the hex - excessive torque adds no sealing benefit. The tube side needs no tools at all: push the Dia 8 hose fully home until it stops, and it is sealed.
