Festo QSL Series Pneumatic Fitting, 4mm Tube Connection size, R 1/4 inches Connection Thread size - QSL-1/4-4, Numeric Part Number: 190659
This pneumatic fitting is a 90° connector designed to join a 4mm plastic tube to a male R1/4 threaded port in pneumatic systems. It provides a Compact elbow connection suitable for control and distribution of compressed Air lines in industrial automation and mechanical assemblies. The component is finished in nickel and MADE from polybutylene terephthalate, configured for push-in tube attachment and right-angle orientation.
Features & Benefits
• Push-in 4mm connection enables quick tube installation
• Male R1/4 thread allows secure mating with R-standard ports
• 90° orientation reduces routing space in tight assemblies
• Nickel finish offers surface protection for metal contact
• Polybutylene terephthalate body sustains mechanical loads
• Rated to 80 °C supports elevated temperature applications
• Male R1/4 thread allows secure mating with R-standard ports
• 90° orientation reduces routing space in tight assemblies
• Nickel finish offers surface protection for metal contact
• Polybutylene terephthalate body sustains mechanical loads
• Rated to 80 °C supports elevated temperature applications

What tube retention method does it use for secure connections?
It employs a push-in mechanism that grips the tube internally, allowing Rapid insertion and straightforward release when required.
What environmental standard does it conform to for material selection?
The component meets RoHS requirements, indicating restricted use of certain hazardous substances in its construction.
Which material property supports its thermal performance up to 80 °C?
The thermoplastic construction provides heat resistance consistent with its maximum operating temperature, maintaining dimensional stability under load.
How does the thread standard affect compatibility with ports?
The R thread follows tapered BSPP-style threading, enabling proper sealing and mechanical engagement with matching R1/4 ports.
