SMC Series AS Pneumatic Elbow Threaded-to-Tube adaptor, 3/8 inches Inlet size, 12mm Outlet size - AS3201F-03-12SA


This pneumatic elbow threaded-to-tube adaptor connects a 3/8in R threaded supply to a 12mm one-touch tubing outlet for controlled pneumatic flow in industrial systems. It is designed for integration into compressed-air installations where a Compact 90° transition from a threaded port to push-in tubing is required, and combines metal and polymer materials to suit demanding mechanical and automation environments.

Features & Benefits


• Maximum operating pressure 1 MPa ensures steady service
• Proof pressure 1.5 MPa provides margin against pressure spikes
• Operating temperature range -5°C to 60°C supports varied environments
• Brass body and PBT components resist wear and corrosion
• One-touch 12mm outlet enables Rapid tubing connection
• Designed as a speed controller pneumatic fitting for flow regulation

**Applications**


• Suitable for machine automation pneumatic control circuits
• Ideal for fitting to valves and actuators requiring 12mm tubing
• Used with pneumatic panels where threaded-to-tube transition is needed
• Can be used for speed control on cylinder exhaust lines
• Used for retrofitting existing 3/8in R ports to modern push-in systems

What construction materials are used and why?


The unit pairs brass for the threaded inlet with PBT polymers for the push-fit section, combining mechanical strength at the connection and lightweight corrosion-resistant properties at the tubing interface.

How does the component behave under overpressure conditions?


It is rated to withstand short-term pressures up to the proof Value of 1.5 MPa, offering a safety margin above normal operating pressure.

What connection standards does the inlet follow?


The inlet uses an R-thread standard sized for 3/8in fittings, allowing compatibility with common tapered threaded ports in industrial equipment.

How does the fitting assist with flow control tasks?


The adaptor functions as a speed controller pneumatic fitting, permitting controlled exhaust or feed rates when installed inline with actuators or control valves.
