    The FD86 is a thread together steel coupling offering dry break and high impulse technology and capabilities. The maximum operating pressure is 5,000 psi.
  • Tubular valve and sleeve construction for low fluid loss and air inclusion.
  • Thread together design using wing or hex nut allows connection and disconnection against pressures up to 750 psi.
  • Teflon® back uop rings along with secondary metal-to-metal sealing contact provides high impulse capability up to 5,000 psi operating pressure.
  • Acme threads prevent galling and provide ease of connection.
  • Metal-to-metal sealing withstands +2000ºF for ten minutes with no fluid loss (requirement in California for oil field blow-out preventers).
  • Steel flange available for bulkhead mounting.
  • Standard seal material - Buna-N.
  • Standard body material - Zinc plated steel.
  • Teflon is a registered trademark of Dupont.
