New Original FESTO 4902 N\u2011M5\u2011PK\u20114 Brass Barbed Pneumatic Fitting<\/h1>\n

Product Overview<\/h2>\n

FESTO N\u2011M5\u2011PK\u20114, part number 4902, is a straight barbed hose fitting from the N\u2011PK barbed fitting series. One end features M5 male metric thread with integrated sealing ring, while the opposite barbed spigot connects to flexible pneumatic tubing with 4\u202fmm inner diameter. Constructed from solid brass, this fitting converts threaded pneumatic ports to flexible hose connections. It is widely deployed in small\u2011bore pneumatic circuits, miniature cylinders, solenoid valves, sensor manifolds, laboratory automation equipment and compact automated machinery. It works for both compressed\u2011air and vacuum circuits and is designed for low\u2011pressure miniature pneumatic system assemblysp-sparepa….<\/p>\n

Main Functions<\/h2>\n
    \n
  1. Interface conversion: Converts M5 male threaded port to barbed connection for flexible soft pneumatic hose.<\/li>\n
  2. Pneumatic fluid transmission: Creates straight\u2011through flow path for compressed air or vacuum flow.<\/li>\n
  3. Secure hose retention: Multi\u2011ridge barbed profile locks flexible hose firmly to prevent hose dislodgement under pressure or vacuum.<\/li>\n
  4. Integrated sealing: Built\u2011in sealing ring at M5 thread eliminates extra external gasket for threaded\u2011port sealing.<\/li>\n
  5. Omni\u2011direction mounting: Can be installed in any spatial orientation without performance loss.<\/li>\n
  6. Simple manual assembly: Hose can be pushed onto barbed tip without special tools; hose clamps can be added for enhanced security.<\/li>\n
  7. Mini\u2011circuit expansion: Supports building compact pneumatic loops for small\u2011size actuators and valves.<\/li>\n
  8. Passive connection component: No moving parts, zero energy consumption for long\u2011term stable connection.<\/li>\n<\/ol>\n

    Technical Characteristics<\/h2>\n
      \n
    • Body material: Machined brass, corrosion\u2011resistant for standard industrial workshop environments.<\/li>\n
    • Integrated NBR sealing ring fitted on M5 male thread for thread\u2011joint sealing.<\/li>\n
    • Multi\u2011ridge barbed spigot for 4\u202fmm inner\u2011diameter flexible pneumatic hose.<\/li>\n
    • Straight\u2011through monolithic brass body, low\u2011restriction internal flow channel.<\/li>\n
    • RoHS compliant and LABS\u2011PWIS compliant per VDMA\u202f24364\u2011B1\/B2\u2011L for paint\u2011industry automation systems.<\/li>\n
    • Wide operating pressure range covering vacuum and positive compressed\u2011air pressure.<\/li>\n
    • Corrosion resistance class CRC\u202f1 for low\u2011corrosion\u2011stress indoor industrial conditions.<\/li>\n
    • Compatible with non\u2011lubricated compressed air; lubricated air is permitted if system maintains consistent lubrication.<\/li>\n<\/ul>\n
