About the Airtac PL L Connector PL603
The PL603 is an AirTAC PL male elbow, a one-touch fitting that turns a 3/8in PT male port through 90 degrees and hands it to a Dia 6 mm tube. Push the tubing into the chuck and the stainless spring gasket and NBR O-ring lock it against the flow; press the POM release ring and the tube slides straight back out. No tools, no tube prep beyond a square cut.
This is the resin and brass one-touch profile: 0-1.0 MPa working pressure (0-10 kgf/cm2), 1.5 MPa proof pressure, -750 mmHg vacuum capability and a -20 to +70 C temperature band with soft nylon or polyurethane tubing. The body is PBT, the stud is brass, and the PT thread arrives from the factory with sealant already applied, so the joint is ready to make as supplied.

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 PL603 Is Used
Gripper cylinders behind machine framing
On a packaging machine the gripper cylinder often sits recessed behind aluminium rails where a straight connector would force a sharp tube bend. The PL603 elbows the run upward out of the 3/8in port, keeping the 6 mm polyurethane line above the minimum bend radius.
Manifold branch step-down
A 3/8in port on a valved manifold is a large hole to feed a small actuator. Fitting the PL603 takes that branch straight down to a Dia 6 line in one part, supplying a labelling head or small clamp cylinder without an extra reducer.
Actuator feeds at conveyor gate corners
Conveyor gate and reject actuators sit tight against side frames, and tube routed from below must turn 90 degrees immediately. The elbow at the PT port does that turn in the fitting, protecting the 6 mm tube from kinking against the guard edge.
Is the Airtac PL L Connector PL603 the Right Part?
On the 3/8in rung of the PL ladder, Dia 6 is the smallest tube AirTAC makes - the thread goes up to Dia 8, 10 and 12 from here, so the next step up is the PL803 with a fatter bore feeding higher-flow runs. Stepping the other way, the PL602 keeps the same 6 mm tube on a 1/4in port, and the PL604 puts it on 1/2in; match the stud to the port thread you actually have drilled or tapped, not the pipe size you wish you had.
Pick an elbow over a straight PC connector whenever the run leaves the port at a right angle - a recessed cylinder port, a wall-mounted manifold face. One caution: the chuck grips a Dia 6 outer diameter exactly, so it will not seal on 1/4in (6.35 mm) tube, even though the numbers look close.
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 PL603 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, usable vacuum to -750 mmHg (10 Torr), operating temperature -20 to +70 C. It joins a Dia 6 mm tube to a 3/8in PT male thread, with the sealant pre-applied on the thread. Soft nylon or polyurethane tubing only.
No. AirTAC ships the 3/8in PT stud with sealant already on the thread, so it seals as installed on a PT tapered port. Hand-tighten first, then finish with a wrench on the hex - overtightening works the sealant back out of the flanks and can crack the PBT body.
