HydroVolt is the most rugged and reliable, low cost underwater electrical connector available — engineered to fill the gap between economical and premium options, with capabilities like color-coded receptacle leads that competing products at this price point don’t offer.
Features & Benefits
Molded Bending Strain Relief
Integrally molded relief that spreads stress over distance, preventing concentrated flexing at the cable/connector joint.
Color Coded Leads
Bulkhead and overmold leads match their mated cable colors, making conductor tracing easier than numbered tags.
Bulkhead Pressure Block
Machined into the metal shell to resist water intrusion during a catastrophic failure.
Gold Plated Contacts
Plated to ASTM B488-01 Type II for corrosion resistance and consistent conductivity over decades of service.
Crimped Contacts
A mechanically stronger termination than solder alone, more resistant to bending fatigue.
Reinforced Bulkhead Neck
Heavy-duty design that resists head separation during aggressive disconnection.
Improved Overmold Sealing
Extended sealing area with an O-ring upset for enhanced boot sealing.
Pin Shoulder Radius
Facilitates mating in difficult conditions and reduces fraying.
