CircuitSeal™ series Douglas Electrical Components



  • Product applications:

    for electrical cables, for printed circuit boards

  • Protection level:



Create hermetic circuit board seals with CircuitSeal™. As the only true hermetic sealing solution for boards, CircuitSeal is ideal for high-volume applications with space or weight constraints.

Directly sealing the circuit board eliminates potential failure points at the electrical connection and allows for increased conductor density while providing a smaller, lighter and less expensive solution. CircuitSeal works on a variety of circuit board styles including flex, rigid, hybrid and flat flex cable (FFC).

Hermetically sealed circuit boards are useful for projects with complex computations. They are also significant in applications that require light and compact sealing methods like missiles or bomb fuses.
