Applications
Pneumatic cylinders
Used for precise speed control and smooth actuator motion
Industrial automation systems
Ensures stable airflow and leak-free operation
Air control systems
Provides accurate airflow regulation
Machinery equipment

Compact pneumatic installations
Combines direction change, sealing, and flow control in one fitting
Product Function
SL-G fittings combine flow control + sealing + direction change in one compact unit.
The integrated needle valve controls airflow, while the O-ring ensures a tight seal at the threaded interface, reducing leakage points and improving system reliability.
Compared to standard SL or PL fittings:
- SL-G = Flow control + elbow + O-ring sealing
- PL = Elbow only (no flow control)

FAQ
Q1: What is an SL-G pneumatic speed controller fitting?
It is a nickel-plated brass elbow fitting with flow control and an O-ring seal for leak-proof pneumatic connections.
Q2: What is the function of the O-ring in pneumatic fittings?
The O-ring provides a tight seal at the threaded connection, preventing air leakage and improving reliability.
Q3: Do I need PTFE tape for SL-G fittings?
No, the built-in O-ring seal eliminates the need for PTFE tape in most applications.
Q4: What is the difference between SL-G and standard speed controllers?
SL-G includes an O-ring sealing system, offering better leak prevention and easier installation.
Q5: What tubing is compatible with SL-G fittings?
SL-G fittings are compatible with PU tubing and nylon tubing.
