Do you offer custom Strain Relief or Bend Limiters?

Yes. The connection point is often the weak link mechanically. HYSF designs and molds custom Polyurethane Bend Limiters and Strain Relief Boots that are tailored to your specific cable diameter and dynamic load requirements. This prevents the cable from exceeding its minimum bending radius right at the connector exit.

protecting the cable-connector interface is critical for dynamic systems (like ROV tethers).

Custom Molding: We machine a custom mold to overmold the strain relief directly onto the cable and connector backshell.
Tapered Design: We calculate the optimal taper profile to distribute the bending load gradually, rather than creating a stress concentration point.
Bonding: Our chemical bonding process ensures the bend limiter doesn’t peel off the cable jacket under tension.
