SMC AS Series Speed Controller Pneumatic Elbow Threaded-to-Tube Adapter, 1/8 in R R 1/8 in One-touch Fitting 4 mm

SMC Series AS Pneumatic Elbow Threaded-to-Tube adaptor, 1/8 inches Inlet size, 4mm Outlet size - AS2301F-01-04SA

This pneumatic elbow threaded-to-tube adaptor provides a Compact Interface between a 1/8 inches R inlet thread and a 4mm push-fit tube, enabling controlled airflow transitions in pneumatic systems. It is intended for use where a right-angle flow connection and adjustable speed control are required, operating within typical industrial pneumatic environments.

Features & Benefits

• Maximum operating pressure 1MPa delivers consistent service performance
  Proof pressure 1.5MPa withstands transient overpressure events
  Operating temperature range -5°C to 60°C permits varied ambient use
  Constructed from brass and PBT for corrosion resistance and weight balance
  One-touch 4mm outlet enables quick tube insertion and release
  Complies with RoHS to limit restricted substances in assemblies

**Applications**

• Suitable for pneumatic speed-regulating valves in automation panels
  Ideal for Compact Air-line routing in machine control cabinets
  Used with miniature actuators requiring right-angle Air feed
  Can be used for test-bench setups needing Rapid tube changes
  Used for retrofitting existing pneumatic manifolds with one-touch tubing

What inlet thread standard does it accept?

The inlet uses an R-format 1/8 inches threaded connection compatible with BSP tapered ports commonly found on pneumatic manifolds.

How does the outlet connection simplify maintenance?

The one-touch fitting accepts 4mm tubing for fast assembly and allows tool-free tube removal to speed replacement cycles.

What materials contact the medium and why are they chosen?

Internal fluid-contact parts are brass for durability, with PBT components to reduce weight and resist chemical exposure typical in compressed-air lines.

Can it operate under fluctuating pressure conditions?

It functions between 0.1MPa and 1MPa during normal operation and is rated to withstand short-term pressure up to 1.5MPa for safety margins.
