New Original FESTO 2257 QM‑1/2‑1/2 Pipe Socket Pneumatic Fitting
Product Overview
The FESTO QM‑1/2‑1/2, part number 2257, is a straight female‑female threaded pipe sleeve from the QM fitting series. It acts as a pneumatic pipe socket coupler to connect two external G1/2 male‑thread pneumatic components together within compressed‑air circuits. Manufactured from anodized wrought aluminum alloy, this fitting provides reliable threaded connection for pneumatic valves, air preparation units, manifold blocks and pneumatic piping systems. It is widely applied in automated production lines, packaging machinery, material‑handling equipment and general‑purpose industrial pneumatic systems for joining threaded pneumatic ports, extending pipe segments and assembling pneumatic control loops. It is suitable for compressed‑air and vacuum working conditions for indoor industrial automation equipment.
Main Functions
- Thread connection coupling: Connects two G1/2 male‑thread pneumatic ports to realize inline pipeline connection.
- Pneumatic circuit extension: Extends or splices threaded pneumatic pipelines without modifying thread specifications.
- Straight through‑type fluid passage: Delivers compressed air or vacuum flow with minimum flow resistance.
- Pipeline assembly and modification: Supports quick on‑site rebuild or expansion of existing pneumatic circuits.
- Uniform internal flow channel: Avoids sharp flow obstructions to maintain stable air‑circuit performance.
- Hex outer profile: Allows standard wrench tightening for convenient installation and disassembly.
- Compatible with standard G thread fittings: Matches FESTO and industry‑standard G‑thread pneumatic accessories.
- Vacuum‑grade usability: Works for negative‑pressure vacuum pneumatic loop assembly.
Technical Characteristics
- Anodized wrought aluminum alloy main body, anti‑corrosion surface treatment for industrial workshop environment.
- Double internal G1/2 parallel female thread structure, straight‑through internal flow channel.
- Hexagonal outer geometry for spanner tool operation during mounting and removal.
- RoHS compliant material composition, meets industrial environmental requirements.
- LABS‑PWIS compliant, suitable for painting‑industry automation equipment applications.
- Wide operating pressure range, adapts to both positive compressed‑air pressure and vacuum conditions.
- Compact solid‑body structure, no internal moving parts, low failure rate and long service life.
- No built‑in sealing gaskets; external sealing rings are required for threaded joint sealing.
