Zero-Leak Gold® Banjo Fittings

Multiple seals distinguish the Zero-Leak Gold Banjo Fitting from traditional washer dependent Banjo fittings. Two separate and independent seals form a double redundant sealing system. A primary metal-to-metal seal works in conjunction with an elastomeric back-up seal to create a zero-leak connection.

Problems with standard Washer Dependent banjo fittings:

  • Attempting a seal with sealing washers is difficult, and it's virtually impossible to reseal reliably.
  • Poor resistance to vibration.
  • High assembly torque is required, possibly resulting in stripped threads and tensile failure of bolts.
  • Components require fine surface finishes on port faces and banjo seats.
  • Flow characteristics are obtained through the difficult and expensive process of
    recessing bodies.
  • Washers may fall off and can be difficult to handle during assembly.
