Can you design custom Penetrators (Feedthroughs) for pressure hulls?
Penetrators are the most secure way to pass cables into a 1-atmosphere housing.
Do you offer custom Strain Relief or Bend Limiters?
protecting the cable-connector interface is critical for dynamic systems (like ROV tethers).
Can you build High-Voltage (HV) connectors above 3,000V?
High voltage underwater is risky.
Do you design connectors for Extreme Temperatures (Cryogenic/Geothermal)?
Temperature extremes cause standard rubber to fail (crack or melt).
Can HYSF Reverse Engineer obsolete or discontinued connectors?
Obsolescence management is a major headache for long-term projects.
Can HYSF assist with Third-Party Certification (DNV / ABS)?
We act as your partner in compliance.
