New Original FESTO 4226 QM\u20113\/4\u20113\/4 Pipe Socket Pneumatic Fitting<\/h1>\n

Product Overview<\/h2>\n

FESTO QM\u20113\/4\u20113\/4, part number 4226, is a straight double\u2011female threaded pipe socket from the QM fitting series. It serves as a pneumatic coupling sleeve for joining two G3\/4 male\u2011thread pneumatic components in compressed\u2011air pipelines. Constructed from anodized wrought aluminum alloy, this fitting creates inline straight connections for air preparation units, valve manifolds, pneumatic valves and threaded pipe segments. It is widely used in automated assembly lines, packaging equipment, material\u2011handling systems and heavy\u2011duty industrial pneumatic circuits. It supports both compressed\u2011air and vacuum conditions and is suitable for general indoor factory automation installationsFesto.<\/p>\n

Main Functions<\/h2>\n
    \n
  1. Straight\u2011through threaded coupling: Connects two G3\/4 male\u2011thread pneumatic ports to form continuous inline pipelines.<\/li>\n
  2. Pneumatic circuit extension: Extends or splices threaded piping without changing thread specification.<\/li>\n
  3. Low\u2011resistance fluid passage: Straight internal bore minimizes flow loss for high\u2011flow compressed\u2011air transmission.<\/li>\n
  4. On\u2011site pipeline modification: Enables quick assembly, reconfiguration and expansion of existing pneumatic loops.<\/li>\n
  5. Hexagon outer profile: Allows standard spanner wrench tightening for convenient installation and disassembly.<\/li>\n
  6. Vacuum\u2011compatible connection: Works reliably for negative\u2011pressure vacuum pneumatic circuits.<\/li>\n
  7. Universal thread compatibility: Matches industry\u2011standard G parallel thread pneumatic accessories.<\/li>\n
  8. Solid passive connection component: No moving parts for stable long\u2011term pipeline linking.<\/li>\n<\/ol>\n

    Technical Characteristics<\/h2>\n
      \n
    • Main body material: Anodized wrought aluminum alloy for industrial anti\u2011corrosion performanceFesto.<\/li>\n
    • Double internal G3\/4 parallel female thread, straight\u2011through internal flow bore.<\/li>\n
    • Hexagonal outer geometry for tool\u2011assisted mounting and removal.<\/li>\n
    • Compliant with RoHS environmental requirements and LABS\u2011PWIS VDMA24364\u2011B1\/B2\u2011L standards for paint\u2011industry automation systemsFesto.<\/li>\n
    • Wide working pressure range covering vacuum and positive compressed\u2011air pressure.<\/li>\n
    • Compact monolithic solid\u2011body design, zero internal moving parts, low failure risk and long service lifespan.<\/li>\n
    • No built\u2011in sealing gaskets; external thread sealing accessories are required for joint sealing.<\/li>\n
    • Suitable for compressed air, vacuum and non\u2011corrosive inert gas working media.<\/li>\n<\/ul>\n
