FAQ
Q1: What is a PLF pneumatic fitting?
It is a push-to-connect female elbow fitting used for 90-degree tube-to-thread connections in pneumatic systems.
Q2: What does “female elbow fitting” mean?
It means the fitting has an internal threaded port and a 90-degree structure for directional connection.
Q3: What is the advantage of a 90 degree elbow fitting?
It allows tubing to change direction and saves installation space in compact systems.
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 is the difference between PL and PLF fittings?
PL uses male thread, while PLF uses female thread.
Q6: What tubing is compatible with PLF fittings?
They are suitable for PU tubing, nylon tubing, and similar pneumatic hoses.
Q7: Where are PLF fittings used?
They are widely used in automation systems, machinery, air compressors, and industrial equipment.
Q8: Can PLF fittings be customized?
Yes, OEM/ODM customization is available for thread types, tube sizes, and materials.
