Dixon MSBC500SSMNPT MannTek Safety Breakaway Coupling marine-grade hose fitting with male NPT threads on both ends. Constructed from 316 stainless steel for corrosion resistance in demanding marine and industrial applications. Designed to automatically separate under excessive tension, preventing hose damage and fluid spills.

Applications

• Coupling is designed to minimize spillage and damage associated with pull away incidents.
• Typically used in ship-to-offshore platform and ship-to-ship product transfer operations

Construction

• 316 Stainless Steel body
• FKM O-rings

Features

• Designed to be installed within a hose string where the coupling will have a length of hose attached to both sides
• Coupling automatically senses an excessive load, closes the valves and disconnects
• Release is executed when force causes bolts to break

How It Works

• The safety breakaway valve consists of two halves, each with a valve that has an O-ring seal. When the safety breakaway couplings separate, it allows the valves to close. The two valves close rapidly, minimizing exposure to personnel and the environment.
• Safety breakaway couplings have three external break bolts. In the case of axial tension all of the bolts take up the force corresponding to the break force on the hose with a safety margin.
