About the Airtac PL L Connector PL803
The PL803 is an AirTAC PL male elbow, a one-touch fitting that turns an 8 mm tube through 90 degrees into a 3/8in PT male thread. Push the polyurethane or soft nylon tube into the chuck and the stainless spring gasket grips it for a pressure-tight joint; press the POM release ring and the tube frees off again. The elbow body is PBT with a brass stud, and the 3/8in thread leaves the factory with sealant already applied, so the port seals without a wrap of PTFE tape.
This is the resin/brass spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr) and a temperature window of -20 to +70 C. If your process runs hotter than 70 C, that is the signal to look at the metal BPC family instead, which trades 0.1 MPa of working pressure for a 150 C ceiling.

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 PL803 Is Used
Side-ported cylinders behind machine guards
On a horizontal clamping cylinder mounted flush inside a press guard, the port faces sideways and a straight connector leaves no clearance. The PL803 turns the 8 mm line through 90deg parallel to the cylinder body, keeping the guard closed.
Valve manifold outlets on packaging machinery
A 3/8in manifold outlet feeding a rotary actuator on a form-fill-seal machine needs the drop line to run down the manifold flank, not outward. This elbow makes that turn at the port while the pre-sealed thread goes straight into the tapped outlet.
Conveyor stopper and gate cylinders
Stopper cylinders along a bottling line conveyor sit in narrow frames where 8 mm tubing must exit downward between guide rails. The PL803 gives that right-angle exit and its release ring lets maintenance swap the line without unscrewing the fitting.
Is the Airtac PL L Connector PL803 the Right Part?
On the 3/8in rung of the PL ladder you can step down to PL603 (Dia 6 tube) or up to PL103 (Dia 10 tube) on the same thread; the smaller bore suits light-duty actuators and signal lines, the larger feeds higher-consumption cylinders. If the port itself is smaller, PL802 drops the thread to 1/4in, and PL804 steps it up to 1/2in for big valve or manifold outlets. Every combination in that ladder is a real AirTAC part, so you can match thread and bore independently.
Match the tube size exactly: this fitting holds Dia 8 tube only, so 5/16in (8 mm nominal) tubing of the wrong wall class or a 1/4in line will not seat in the chuck. Choose the PL shape when the tube has to leave the port at right angles - a straight PC connector standing proud of a side-mounted cylinder will foul guards and cable chains where this elbow tucks in.
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 PL803 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability down to -750 mmHg (10 Torr), operating temperature -20 to +70 C. It connects Dia 8 mm soft nylon or polyurethane tube to a 3/8in PT male thread. The body is PBT with a brass stud, POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
No. AirTAC ships PL threaded fittings with sealant already applied to the male thread, so it seals directly into the tapped port. If you ever refit it, clean off the old sealant and re-apply a compatible pipe sealant rather than relying on the residue - and remember the thread standard here is PT throughout this catalogue, so pair it with a PT or taper-matching port, not a parallel G port.
