Extended 90-Degree Connections for Added Tube Routing Clearance
The PLL Series push-to-connect fitting provides an extended 90-degree connection between pneumatic tubing and a compatible male-threaded port. It combines a one-touch pneumatic tube connection with a compact fitting body for use on industrial automation and general compressed air equipment.
The source fitting range is designed so compatible tubing can be connected, disconnected and reconnected without normally damaging the tube or fitting. This supports fast assembly and easier maintenance on valves, cylinders, manifolds and machine-air circuits.

Frequently Asked Questions
What is the PLL Series fitting used for?
The PLL Series fitting is used for an extended 90-degree connection between pneumatic tubing and a compatible male-threaded port.
How does the push-to-connect tube connection work?
Compatible pneumatic tubing is pushed into the fitting until the internal gripping and sealing components retain it. The tube can be released using the collar when the system is safely depressurized.
What tubing is commonly used?
The source description identifies polyurethane and nylon pneumatic tubing as common materials.
What is the listed working pressure?
The source specification lists 0–150 psi(g) / 10 bar(g).
What is the listed proof pressure?
The source specification lists 450 psi(g) / 30 bar(g).
Can this fitting be used for vacuum?
The source specification lists vacuum duty to 29.5 inHg / 14 mbar(a).
What is the listed working temperature?
The source specification lists 32–140°F / 0–60°C, with high-temperature models available on request.
How do I select the correct fitting?
Confirm tube outside diameter, mating thread, extended male elbow, pressure, temperature and installation clearance.
