Mustang Survival 78022 Hydrostatic Release Unit HRU for Life Rafts EPIRBs Safety Parts & Accessories

The Mustang Survival 78022 is a hydrostatic release unit (HRU) designed for use with automatically deployable life rafts and EPIRBs in marine safety systems. The HRU is a critical safety device that automatically releases a life raft or EPIRB when submerged to a depth of 1.5 to 4 meters (approximately 5 to 13 feet), allowing the equipment to float free and deploy even if a vessel sinks rapidly.

Key Features:

• Automatically activates at a water depth of 1.5–4 meters (5–13 ft)
• Designed for use with inflatable life rafts and float-free EPIRB bracket systems
• Constructed for reliable performance in harsh marine environments
• Meets international marine safety standards for hydrostatic release
• Replacement/service unit to maintain compliance with required inspection intervals
• Compact and lightweight design for easy installation

HRUs require periodic replacement per manufacturer and SOLAS/USCG guidelines — typically every 2 years. The Mustang Survival 78022 ensures your life raft or EPIRB float-free system remains fully operational and compliant with current safety regulations.
