The Bcd Corrugated Hose plays an important role in channeling breathing gases between scuba system components and the diver.
A corrugated breathing hose is a type of flexible rubber or elastomer tube with a corrugated surface, specially designed for use in scuba breathing systems.Â
Main Functions
A corrugated breathing hose is used to:
- Flow breathing gases to and from the diver’s mouth.
- Connect components such as a mouthpiece, counter lung, or canister in a rebreather system.
- Allow free movement of the diver’s head and body without obstructing the flow of breath.
Design Features
Corrugated structure
The corrugated design allows the hose to be more flexible, easy to bend, and resistant to kinks even when bent repeatedly.
High-quality rubber or elastomer material
Usually made of synthetic rubber or elastomer material that is resistant to salt water, high pressure, and aging due to the marine environment.
Airtight and safe for breathing
Designed to prevent gas leakage and not release harmful substances that can contaminate the breathing air.
Applications in Scuba Systems
Corrugated breathing hoses are commonly used in:
Specialized or technical scuba breathing systems that require a flexible and reliable gas path
Sizes and Lengths
Corrugated breathing hoses are typically available in a variety of sizes and lengths to suit user needs and equipment configurations. For example:
A 16-inch length is often used to provide a balance between flexibility and comfort of movement
Other sizes are also available depending on the system design and diver ergonomics
Conclusion
In short, corrugated breathing hoses are an essential component of scuba equipment, especially rebreather systems. Their flexible, durable, and safe design ensures smooth breathing gas flow as well as diver comfort and safety during diving activities.
