Mustang Survival 83023 Hydrostatic Release Unit (HRU) for Life Jackets

The Mustang Survival 83023 Hydrostatic Release Unit (HRU) is a critical marine safety component designed to automatically trigger deployment of inflatable life jackets or safety devices when submerged in water. Engineered to meet strict maritime safety standards, this HRU provides reliable automatic activation without any manual intervention — a vital feature in man-overboard or vessel-sinking emergencies.

Key Features:

• Automatic hydrostatic activation — triggers at a preset water depth, typically 1–4 meters
• Compatible with Mustang Survival inflatable PFD systems
• Durable, corrosion-resistant construction for harsh marine environments
• Replacement/service component — ensures your inflatable PFD remains in certified, ready-to-deploy condition
• Easy installation on compatible Mustang Survival inflatable life jackets and PFDs

Regular replacement of the HRU is required as part of scheduled PFD maintenance to maintain certification and ensure reliable performance. The Mustang Survival 83023 is the OEM-specified replacement unit for compatible Mustang inflatable personal flotation devices.
