Extreme Sealing for maximum realiability and maximum risk

Extreme sealing for maximum reliability & minimum risk

Guaranteeing extreme sealing to maximize reliability and reduce risks

When designing your equipment, choosing the right connectivity solutions with the right type of sealing early in the process is critical for the commercial success and durability of your product.

Not all IP68 ratings are created equal. Learn here why Fischer Connectors have has some of the toughest IP68 rated connectors in the industry, tested to a minimum of 2 meters for 24 hours and up to 120 meters for 24 hours. Custom designs can give you even more.

Types: Environmental. Hermetic. High pressure.

Sealing is a complex science, involving physical aspects such as mechanical design, materials & surface science and fluid behavior.

There are three main sealing levels and solutions:

  • Environmental sealing, for equipment used outdoors and exposed to rain, dust or other aggressors for a limited time and limited pressure
  • Hermetic sealing, for vacuum applications, pressurized vessels or equipment used underwater, exposed for a longer time
  • High pressure sealing, for applications exposed to high pressure for extended periods

Application examples: Instrumentation. Underwater. Oil & gas.

  • Most instrumentation applications, which depend on data reliability, require rugged connectors sealed to IP68/IP69 to protect devices from environmental interference, or hermetic vacuum and pressurized equipment to prevent gas leaks.
  • As underwater applications may involve immersion over long periods, they require IP68 waterproof sealing.
  • As oil & gas applications are exposed to high pressures, shock and vibration, their sealing needs must be combined with high-strength mechanical design to guarantee safe and efficient operations.

Worldwide reputation: Fischer Connectors’ sealing technology & know-how.

Fischer Connectors keeps innovating in tested ultra-sealed connectivity solutions, increasing our track-record of customers who, for more 60 years, have chosen us for our proven reputation in watertight and hermetic, standard & custom solutions.
