TECVAL chc-1x1


TECVAL Data sheet CHC

Data sheet

The CHC two-ferrule compressing fittings are used to assemble on 90º a threated or welding end to a metric or fractional tube. The resulting union is completely hermetic, both for high pressure and high temperatures.


  • Easy and fast mounting.
  • Resistant to vibration.
  • Hard fastening and union without twisting.
  • Anti-leakage guarantee.
  • Metric tube from 4mm to 25mm.
  • Fractional tube from 1/8" to 1".
  • Threaded NPT ends according to ANSI B1.20.1.
  • Threaded BSP ends according to DIN ISO 228-1.
  • Socket Weld SW ends according to ANSI B16.25
