FAQ
Q1: What is a PLL pneumatic fitting?
It is an extended male elbow push-to-connect fitting used for 90-degree tube-to-thread connections.
Q2: What does “extended elbow fitting” mean?
It means the fitting has a longer body design, providing extra height and clearance for installation.
Q3: What is the advantage of a PLL fitting over a standard PL fitting?
PLL fittings reduce interference and allow easier installation in tight or crowded spaces.
Q4: How does a push-to-connect fitting work?
The tube is inserted and locked by internal gripping teeth, while an O-ring ensures sealing.
Q5: What tubing is compatible with PLL fittings?
They are suitable for PU tubing, nylon tubing, and similar pneumatic hoses.
Q6: Where are PLL fittings used?
They are widely used in automation systems, robotics, industrial machinery, and compact installations.
Q7: What is the working pressure of PLL fittings?
They typically operate within 0–1.0 MPa depending on configuration.
Q8: Can PLL fittings be customized?
Yes, OEM/ODM customization is available for thread type, tube size, materials, and design.
