HYSF SF33M-HSCM Hybrid Photoelectric 2+2 External Thread Protective Cap

HYSF SF33M-HSCM Hybrid Photoelectric 2+2 External Thread Protective Cap

The HYSF SF33M-HSCM is a protective external thread cap for hybrid photoelectric 2 optical 2 electrical connectors, designed to seal and safeguard unused male threads from contamination, seawater ingress, and corrosion in harsh marine environments. Essential accessory for maintaining connector integrity during storage, transport, or deployment of ROVs, AUVs, underwater lighting systems, and subsea hybrid equipment. Made from durable marine-grade materials with secure threading, it provides complete pressure-resistant protection at deep ocean depths. Critical for preserving hybrid opto-electric underwater connector lifespan and ensuring reliable performance in offshore applications from China manufacturer HYSF.
