Can HYSF connectors replace SubConn® or Seacon® products?

Yes, HYSF connectors are designed for Global Compatibility. Our products feature full interface interchangeability with leading domestic and international brands (such as SubConn® and Seacon®), matching international standards for sealing and mechanical reliability.

One of HYSF’s core competencies is “Import Substitution”. We understand that engineers need reliable alternatives without changing their existing system designs.

  • Interchangeability: Our Micro Watertight Connectors and Standard Series are engineered to mate perfectly with existing bulkheads or cables from major global brands.
  • Performance Match: Our connectors offer equivalent or superior specifications, such as a 60MPa pressure rating and wet-mateable technology.
  • Cost Advantage: We provide a high-performance solution that breaks the premium pricing of international monopolies.

Whether you need a 7/16-20UNF Micro connector or a high-power interface, HYSF offers a seamless, drop-in replacement.
