## Product Summary

SL-G pneumatic fittings are speed controller push-to-connect valves designed for precise airflow regulation and cylinder speed control in pneumatic systems.

With an integrated throttle valve structure, SL-G fittings allow users to adjust airflow rate, enabling accurate control of actuator speed and system performance.

The fitting uses a nickel-plated brass body combined with an O-ring sealing system to ensure corrosion resistance, stable sealing, and long service life.

Push-to-connect design allows fast tube installation without tools, while the adjustable knob provides easy and precise flow control.

OEM and ODM customization services are available for thread types, tube sizes, and control specifications.
